In the past, this may have been done utilizing `cron`, but it can be frustrating to have your scheduling logic disconnected from your code. -To make this easy, Alchemy provides a clean API for scheduling repeated tasks & jobs. - -### Scheduling - -You can schedule recurring work for your application using the `schedule()` function. You'll probably want to do this in your `boot()` function. This returns a builder with which you can customize the frequency of the task. - -```swift -struct ExampleApp: Application { - func boot() { - schedule { print("Good morning!") } - .daily() - } -} -``` - -#### Scheduling Jobs - -You can also schedule jobs to be dispatched.

See [SwiftLog](https://github.com/apple/swift-log) for advanced usage. - -## Thread - -As mentioned in [Under the Hood](12_UnderTheHood.md), you'll want to avoid blocking the current `EventLoop` as much as possible to help your server have maximum request throughput. - -Should you need to do some blocking work, such as file IO or CPU intensive work, `Thread` provides a dead simple interface for running work on a separate (non-`EventLoop`) thread. - -Initiate work with `Thread.run` which takes a closure, runs it on a separate thread, and returns the value generated by the closure back on the initiating `EventLoop`. - -```swift -Thread - .run { - // Will be run on a separate thread. - blockingWork() - } - .whenSuccess { value in - // Back on the initiating `EventLoop`, with access to any value - // returned by `blockingWork()`. - } -``` - -## Making HTTP Requests - -HTTP requests should be made with [AsyncHTTPClient](https://github.com/swift-server/async-http-client).

With Plot, returning HTML is dead simple and elegant. You can do so straight from a `Router` handler. - -```swift -app.get("/website") { _ in - return HTML { - .head( - .title("My website"), - .stylesheet("styles.css") - ), - .body( - .div( - .h1(.class("title"), "My website"), - .p("Writing HTML in Swift is pretty great!") - ) - ) - } -} -``` - -### Control Flow - -Plot also supports inline control flow with conditionals, loops, and even unwrapping. It's the perfect, type safe substitute for a templating language. - -```swift -let animals: [String] = ... -let showSubtitle: Bool = ... -let username: String? = ... -HTML { - .head( - .title("My website"), - .stylesheet("styles.css") - ), - .body( - .div( - .h1("My favorite animals are..."), - .if(showSubtitle, - .h2("You found the subtitle") - ), - .ul(.forEach(animals) { - .li(.class("name"), .text($0)) - }), - .unwrap(username) { - .p("Hello, \(username)") - } - ) - ) -} -``` - -### HTMLView - -You can use the `HTMLView` type to help organize your projects view and pages. It is a simple protocol with a single requirement, `var content: HTML`. Like `HTML`, `HTMLView`s can be returned directly from a `Router` handler. - -```swift -struct HomeView: HTMLView { - let showSubtitle: Bool - let animals: [String] - let username: String? - - var content: HTML { - HTML { - .head( - .title("My website"), - .stylesheet("styles.css") - ), - .body( - .div( - .h1("My favorite animals are..."), - .if(self.showSubtitle, - .h2("You found the subtitle") - ), - .ul(.forEach(self.animals) { - .li(.class("name"), .text($0)) - }), - .unwrap(self.username) { - .p("Hello, \(username)") - } - ) - ) - } - } -} - -app.get("/home") { _ in - HomeView(showSubtitle: true, animals: ["Orangutan", "Axolotl", "Echidna"], username: "Kendra") -} -``` - -### Plot Docs - -Check out the [Plot docs](https://github.com/JohnSundell/Plot) for everything you can do with it. - -## Serving Static Files - -If you'd like to serve files from a static directory, there's a `Middleware` for that. It will match incoming requests to files in the directory, streaming those back to the client if they exist. By default, it serves from `Public/` but you may pass a custom path in the initializer if you like. - -Consider a `Public` directory in your project with a few files. - -``` -│ -├── Public -│ ├── css -│ │ └── style.css -│ ├── js -│ │ └── app.js -│ ├── images -│ │ └── puppy.png -│ └── index.html -│ -├── Sources -├── Tests -└── Package.swift -``` - -You could use the following code to serve files from that directory. - -```swift -app.useAll(StaticFileMiddleware()) -``` - -Now, assets in the `Public/` directory can be requested. -``` -http://localhost:3000/index.html -http://localhost:3000/css/style.css -http://localhost:3000/js/app.js -http://localhost:3000/images/puppy.png -http://localhost:3000/ (by default, will return any `index.html` file) -``` - -**Note**: The given directory is relative to your server's working directory.

This means that each request your server handles is assigned/run on an "event loop", a thread designated for handling incoming requests (represented by the `NIO.EventLoop` type). - -## Event Loops and You - -There are as many unique `EventLoop`s as there are logical cores on your machine, and as requests come in, they are distributed between them. For the most part, logic around `EventLoop`s is abstracted away for you, but there are a few caveats to be aware of when building with Alchemy. - -### Caveat 1: **Don't block `EventLoop`s!** - -The faster you finish handling a request, the sooner the `EventLoop` it's running on will be able to handle additional requests. To keep your server fast, don't block the event loops on which your router handlers are run. If you need to do some CPU intensive work, spin up another thread with `Thread.run`. This will allow the `EventLoop` of the request to handle other work while your intesive task is being completed on another thread. When the task is done, it will hop back to it's original `EventLoop` where it's handling can be finished. - -### Caveat 2: **Use non-blocking APIs (`EventLoopFuture`) when doing async tasks** - -Often, handling a request involves waiting for other servers / services to do something. This could include making a database query or making an external HTTP request. So that EventLoop threads aren't blocked, Alchemy leverages `EventLoopFuture`. `EventLoopFuture` is the Swift server world's version of a `Future`. It represents an asynchronous operation that hasn't yet completed, but will complete on a specific `EventLoop` with either an `Error` or a value of `T`. - -If you've worked with other future types before, these should be straighforward; the API reference is [here](https://apple.github.io/swift-nio/docs/current/NIO/Classes/EventLoopFuture.html). If you haven't, think of them as functional sugar around a value that you'll get in the future (i.e. is being fetched asynchronously). You can chain functions that change the value (`.map { ... }`) or change the value asynchronously (`.flatMap { ... }`) and then respond to the value (or an error) when it's finally resolved. - -#### Creating a new `EventLoopFuture` - -If needed, you can easily create a new future associated with the current `EventLoop` via `EventLoopFuture.new(error:)` or `EventLoopFuture.new(_ value:)`. These will resolve immediately on the current `EventLoop` with the value or error passed to them. - -```swift -func someHandler() -> EventLoopFuture { - .new("Hello!") -} - -func unimplementedHandler() -> EventLoopFuture { - .new(error: HTTPError(.notImplemented, message: "This endpoint isn't implemented yet")) -} -``` - -### Accessing `EventLoop`s or `EventLoopGroup`s - -In general, you won't need to access or think about any `EventLoop`s, but if you do, you can get the current one with `Loop.current`. - -```swift -let thisLoop: EventLoop = Loop.current -``` - -Should you need an `EventLoopGroup` for other `NIO` based libraries, you can access the global `EventLoopGroup` (a `MultiThreadedEventLoopGroup`) via `Loop.group`. - -```swift -let appLoopGroup: EventLoopGroup = Loop.group -``` - -Finally, should you need to run an expensive operation, you may use `Thread.run` which uses an entirely separate thread pool instead of blocking any of your app's `EventLoop`s. - -_[Table of Contents](/Docs#docs)_ diff --git a/Docs/13_Commands.md b/Docs/13_Commands.md deleted file mode 100644 index 49b6fea1..00000000 --- a/Docs/13_Commands.md +++ /dev/null @@ -1,138 +0,0 @@ -# Commands - -- [Writing a custom Command](#writing-a-custom-command) - * [Adding Options, Flags, and help info](#adding-options-flags-and-help-info) - * [Printing help info](#printing-help-info) -- [`make` Commands](#make-commands) - -Often, you'll want to run specific tasks around maintenance, cleanup or productivity for your Alchemy app. - -The `Command` interface makes this a cinche, allowing you to create custom commands to run your application with.

There's also support for adding help & discussion strings that will show if your app is run with the `help` argument. - -```swift -final class SyncUserData: Command { - static var configuration = CommandConfiguration(commandName: "sync", discussion: "Sync all data for all users.") - - @Option var id: Int? - @Flag(help: "Loaded data but don't save it.") var dry: Bool = false - - func start() -> EventLoopFuture { - if let userId = id { - // sync only a specific user's data - } else { - // sync all users' data - } - } -} -``` - -You can now pass options and flags to this command like so `swift run MyApp sync --id 2 --dry` and it run with the given arguments. - -### Printing help info - -Out of the box, your server can be run with the `help` argument to show all commands available to it, including any custom ones your may have registered. - -```bash -$ swift run MyApp help -OVERVIEW: Run an Alchemy app. - -USAGE: launch [--env ] - -OPTIONS: - -e, --env (default: env) - -h, --help Show help information. - -SUBCOMMANDS: - serve (default) - migrate - queue - make:controller - make:middleware - make:migration - make:model - make:job - make:view - sync - - See 'launch help ' for detailed help. -``` - -You can also pass a command name after help to get detailed information on that command, based on the information your provide in your `configuration`, options, flags, etc. - -```bash -$ swift run MyApp help sync -OVERVIEW: -Sync all data for all users. - -USAGE: MyApp sync [--id ] [--dry] - -OPTIONS: - -e, --env (default: env) - --id Sync data for a specific user only. - --dry Should data be loaded but not saved. - -h, --help Show help information. -``` - -Note that you can always pass `-e, --env ` to any command to have it load your environment from a custom env file before running. - -## `make` Commands - -Out of the box, Alchemy includes a variety of commands to boost your productivity and generate commonly used interfaces. These commands are prefaced with `make:`, and you can see all available ones with `swift run MyApp help`. - -For example, the `make:model` command makes it easy to generate a model with the given fields.

The `@GET("/todos")` indicates that the endpoint is at `POST {some_base_url}/todos`. -2. The endpoint expects a request object of `GetUsersRequest` which conforms to `RequestComponents` and contains two properties, wrapped by `@URLQuery`. The `URLQuery` wrappers indicate data that's expected in the query url of the request. This lets requesters of this endpoint know that the endpoint needs two query values, `limit` and `incompleteOnly`. It also lets the providers of this endpoint know that incoming requests to `GET /todo` will contain two items in their query URLs; `limit` and `incompleteOnly`. -3. The endpoint has a response type of `[TodoDTO]`, defined below it. This lets clients know what response type to expect and lets providers know what response type to return. - -This gives anyone reading or using the API all the information they would need to interact with it. - -Requesting this endpoint might look like -``` -GET {some_base_url}/todos?limit=1&incompleteOnly=0 -``` -While a response would look like -```json -[ - { - "name": "Do laundry", - "isComplete": false - }, - { - "name": "Learn Alchemy", - "isComplete": true - }, - { - "name": "Be awesome", - "isComplete": true - }, -] -``` - -**Note**: The DTO suffix of `TodoDTO` stands for `Data Transfer Object`, indicating that this type represents some data moving across the wire. It is not necesssary, but helps differentiate from local `Todo` model types that may exist on either client or server. - -#### Supported Methods - -Out of the box, Papyrus provides `@GET`, `@POST`, `@PUT`, `@PATCH`, `@DELETE` as well as a `@CUSTOM("OPTIONS", "/some/path")` that can take any method string for defining your `Endpoint`s. - -#### Empty Request or Reponse - -If you're endpoint doesn't have any request or response data that needs to be parsed, you may define the `Request` or `Response` type to be `Empty`. - -```swift -class SomeAPI: EndpointGroup { - @GET("/foo") - var noRequest: Endpoint - - @POST("/bar") - var noResponse: Endpoint -} -``` - -#### Custom Request Data - -Like `@URLQuery`, there are other property wrappers to define where on an HTTP request data should be. - -Each wrapper denotes a value in the request at the proper location with a key of the name of the property. For example `@Header var someHeader: String` indicates requests to this endpoint should have a header named `someHeader`. - -**Note**: `@Body` ignore's its property name and instead encodes it's value into the entire request body. - -##### URLQuery - -`@URLQuery` can wrap a `Bool`, `String`, `String?`, `Int`, `Int?` or `[String]`. - -Optional properties with nil values will be omitted. - -```swift -class SomeAPI: EndpointGroup { - // There will be a query1, query3 and optional query2 in the request URL. - @GET("/foo") - var queryRequest: Endpoint -} - -struct QueryRequest: RequestComponents { - @URLQuery var query1: String - @URLQuery var query2: String? - @URLQuery var query3: Int -} -``` - -##### Header - -`@Header` can wrap a `String`. It indicates that there should be a header of name `{propertyName}` on the request. - -```swift -class SomeAPI: EndpointGroup { - @POST("/foo") - var foo: Endpoint -} - -/// Defines a header "someHeader" on the request. -struct HeaderRequest: RequestComponents { - @Header var someHeader: String -} -``` - -##### Path Parameters - -`@Path` can wrap a `String`. It indicates a dynamic path parameter at `:{propertyName}` in the request path. - -```swift -class SomeAPI: EndpointGroup { - @POST("/some/:someID/value") - var foo: Endpoint -} - -struct PathRequest: RequestComponents { - @Path var someID: String -} -``` - -##### Body - -`@Body` can wrap any `Codable` type which will be encoded to the request. By default, the body is encoded as JSON, but you may override `RequestComponents.contentType` to use another encoding type. - -```swift -class SomeAPI: EndpointGroup { - @POST("/json") - var json: Endpoint - - @GET("/url") - var json: Endpoint -} - -/// Will encode `BodyData` in the request body. -struct JSONBody: RequestComponents { - @Body var body: BodyData -} - -/// Will encode `BodyData` in the request URL. -struct URLEncodedBody: RequestComponents { - static let contentType = .urlEncoded - - @Body var body: BodyData -} - -struct BodyData: Codable { - var foo: String - var baz: Int -} -``` - -You may also use `RequestBody` if the only content of the request is in the body. This will encode whatever fields are on your type into the `Request`'s body, instead of having to add a separate type and use the `@Body` property wrapper. - -```swift -struct JSONBody: RequestBody { - var foo: String - var baz: Int -} -``` - -##### Combinations - -You can combine any number of these property wrappers, except for `@Body`. There can only be a single `@Body` per request. - -```swift -struct MyCustomRequest: RequestComponents { - struct SomeCodable: Codable { - ... - } - - @Body var bodyData: SomeCodable - - @Header var someHeader: String - - @Path var userID: String - - @URLQuery var query1: Int - @URLQuery var query2: String - @URLQuery var query3: String? - @URLQuery var query3: [String] -} -``` - -### Requesting APIs - -Papyrus can be used to request endpoints on client or server targets. - -To request an endpoint, create the `EndpointGroup` with a `baseURL` and call `request` on a specific endpoint, providing the needed `Request` type. - -Requesting the the `TodosAPI.getAll` endpoint from above looks similar on both client and server. - -```swift -// `import PapyrusAlamofire` on client -import Alchemy - -let todosAPI = TodosAPI(baseURL: "http://localhost:3000") -todosAPI.getAll - .request(.init(limit: 50, incompleteOnly: true)) { response, todoResult in - switch todoResult { - case .success(let todos): - for todo in todos { - print("Got todo: \(todo.name)") - } - case .failure(let error): - print("Got error: \(error).") - } - } -``` - -This would make a request that looks like: -``` -GET http://localhost:3000/todos?limit=50&incompleteOnly=false -``` - -While the APIs are built to look similar, the client and server implementations sit on top of different HTTP libraries and are customizable in separate ways. - -#### Client, via Alamofire - -Requesting an `Endpoint` client side is built on top of [Alamofire](https://github.com/Alamofire/Alamofire). By default, requests are run on `Session.default`, but you may provide a custom `Session` for any customization, interceptors, etc. - -#### Server, via AsyncHTTPClient - -Request an `Endpoint` in an `Alchemy` server is built on top of [AsyncHTTPClient](https://github.com/swift-server/async-http-client). By default, requests are run on the default `HTTPClient`, but you may provide a custom `HTTPClient`. - -### Providing APIs - -Alchemy contains convenient extensions for registering your `Endpoint`s on a `Router`. Use `.on` to register an `Endpoint` to a router. - -```swift -let todos = TodosAPI() -router.on(todos.getAll) { (request: Request, data: GetTodosRequest) in - // when a request to `GET /todos` is handled, the `GetTodosRequest` properties will be loaded from the `Alchemy.Request`. -} -``` - -This will automatically parse the relevant `GetTodosRequest` data from the right places (URL query, headers, body, path parameters) on the incoming request. In this case, "limit" & "incompleteOnly" from the request query `String`. - -If expected data is missing, a `400` is thrown describing the missing expected fields: - -```json -400 Bad Request -{ - "message": "expected query value `limit`" -} -``` - -**Note**: Currently, only `ContentType.json` is supported for decoding request `@Body`s. - -### Interceptors - -Often you'll have some sort of request component you'd like to apply to every request in a group of endpoints. For example, you may want to add an `Authorization` header. Instead of adding `@Header var authorization: String` to each request content, you can accomplish this using the `intercept()` function of `EndpointGroup`. It gives you the raw `HTTPComponents` to modify right before sending the request. - -```swift -final class TodoAPI: EndpointGroup { - @POST("/v1/create") var create: Endpoint - @POST("/v1/create") var getAll: Endpoint - @POST("/v1/create") var delete: Endpoint - - func intercept(_ components: inout HTTPComponents) { - components.headers["Authorization"] = "Bearer \(some_token)" - } -} -``` - -_Next page: [Database: Basics](5a_DatabaseBasics.md)_ - -_[Table of Contents](/Docs#docs)_ diff --git a/Docs/5a_DatabaseBasics.md b/Docs/5a_DatabaseBasics.md deleted file mode 100644 index bfec85e9..00000000 --- a/Docs/5a_DatabaseBasics.md +++ /dev/null @@ -1,97 +0,0 @@ -# Database: Basics - -- [Introduction](#introduction) -- [Connecting to a Database](#connecting-to-a-database) -- [Querying data](#querying-data) - * [Handling Query Responses](#handling-query-responses) - * [Transactions](#transactions) - -## Introduction - -Alchemy makes interacting with SQL databases a breeze.

It can be used for the majority of database operations, otherwise you can always run pure SQL as well. The syntax is heavily inspired by Knex and Laravel. - -## Running Database Queries - -### Starting a query chain -To start fetching records, you can begin a chain a number of different ways. Each will start a query builder chain that you can then build out. - -```swift -Query.from("users")... // Start a query on table `users` using the default database. -// or -Model.query()... // Start a query and automatically sets the table from the model. -// or -database.query().from("users") // Start a query using a database variable on table `users`. -``` - -### Get all rows -```swift -Query.from("users") - .get() -``` - -### Get a single row - -If you are only wanting to select a single row from the database table, you have a few different options. - -To select the first row only from a query, use the `first` method. -```swift -Query.from("users") - .where("name", "Steve") - .first() -``` - -If you want to get a single record based on a given column, you can use the `find` method. This will return the first record matching the criteria. -```swift -Query.from("users") - .find() -``` - -## Select - -### Picking columns to return - -Sometimes you may want to select just a subset of columns to return. While the `find` and `get` methods can take a list of columns to limit down to, you can always explicitly call `select`. - -```swift -Query.from("users") - .select(["first_name", "last_name"]) - .get() -``` - -## Joins - -You can easily join data from separate tables using the query builder. The `join` method needs the table you are joining, and a clause to match up the data. If for example you are wanting to join all of a users order data, you could do the following: - -```swift -Query.from("users") - .join(table: "orders", first: "users.id", op: .equals, second: "orders.user_id") - .get() -``` - -There are helper methods available for `leftJoin`, `rightJoin` and `crossJoin` that you can use that take the same basic parameters. - -## Where Clauses - -### Basic Where Clauses - -If you are wanting to filter down your results this can be done by using the `where` method. You can add as many where clauses to your query to continually filter down as far as needed. The simplest usage is to construct a `WhereValue` clause using some of the common operators. To do this, you would pass a column, the operator and then the value. For example if you wanted to get all users over 20 years old, you could do so as follows: - -```swift -Query.from("users") - .where("age" > 20) - .get() -``` - -The following operators are valid when constructing a `WhereValue` in this way: `==`, `!=`, `<`, `>`, `<=`, `>=`, `~=`. - -Alternatively you can manually create a `WhereValue` clause manually: - -```swift -Query.from("users") - .where(WhereValue(key: "age", op: .equals, value: 10)) - .get() -``` - -### Or Where Clauses - -By default chaining where clauses will be joined together using the `and` operator. If you ever need to switch the operator to `or` you can do so by using the `orWhere` method. - -```swift -Query.from("users") - .where("age" > 20) - .orWhere("age" < 50) - .get() -``` - -### Grouping Where Clauses - -If you need to group where clauses together, you can do so by using a closure. This will execute those clauses together within parenthesis to achieve your desired logical grouping. - -```swift -Query.from("users") - .where { - $0.where("age" < 30) - .orWhere("first_name" == "Paul") - } - .orWhere { - $0.where("age" > 50) - .orWhere("first_name" == "Karen") - } - .get() -``` - -The provided example would produce the following SQL: - -```sql -select * from users where (age < 50 or first_name = 'Paul') and (age > 50 or first_name = 'Karen') -``` - -### Additional Where Clauses - -There are some additional helper where methods available for common cases. All methods also have a corresponding `or` method as well. - -#### Where Null - -The `whereNull` method ensures that the given column is not null. - -```swift -Query.from("users") - .whereNull("last_name") - .get() -``` - -#### Where In - -The `where(key: String, in values [Parameter])` method lets you pass an array of values to match the column against. - -```swift -Query.from("users") - .where(key: "age", in: [10,20,30]) - .get() -``` - -## Ordering, Grouping, Paging - -### Grouping - -To group results together, you can use the `groupBy` method: - -```swift -Query.from("users") - .groupBy("age") - .get() -``` - -If you need to filter the grouped by rows, you can use the `having` method which performs similar to a `where` clause. - -```swift -Query.from("users") - .groupBy("age") - .having("age" > 100) - .get() -``` - -### Ordering - -You can sort results of a query by using the `orderBy` method. - -```swift -Query.from("users") - .orderBy("first_name", direction: .asc) - .get() -``` - -If you need to sort by multiple columns, you can add `orderBy` as many times as needed. Sorting is based on call order. - -```swift -Query.from("users") - .orderBy("first_name", direction: .asc) - .orderBy("last_name", direction: .desc) - .get() -``` - -### Paging, Limits and Offsets - -If all you are looking for is to break a query down into chunks for paging, the easiest way to accomplish that is to use the `forPage` method. It will automatically set the limits and offsets appropriate for a page size you define. - -```swift -Query.from("users") - .forPage(page: 1, perPage: 25) - .get() -``` - -Otherwise, you can also define limits and offsets manually: -```swift -Query.from("users") - .offset(50) - .limit(10) - .get() -``` - -## Inserting - -You can insert records using the query builder as well. To do so, start a chain with only a table name, and then pass the record you wish to insert. You can additionally pass in an array of records to do a bulk insert. - -```swift -Query.table("users") - .insert([ - "first_name": "Steve", - "last_name": "Jobs" - ]) -``` - -## Updating - -Updating records is just as easy as inserting, however you also get the benefit of the rest of the query builder chain. Any where clauses that have been added are used to match which records you want to update. For example, if you wanted to update a single user based on an ID, you could do so as follows: - -```swift -Query.table("users") - .where("id" == 10) - .update(values: [ - "first_name": "Ashley" - ]) -``` - -## Deleting - -The `delete` method works similar to how `update` did. It uses the query builder chain to determine what records match, but then instead of updating them, it deletes them. If you wanted to delete all users whose name is Peter, you could do that as so: - -```swift -Query.table("users") - .where("name" == "Peter") - .delete() -``` - -## Counting - -To get the total number of records that match a query you can use the `count` method. - -```swift -Query.from("rentals") - .where("num_beds" >= 1) - .count(as: "rentals_count") -``` - -_Next page: [Database: Migrations](5c_DatabaseMigrations.md)_ - -_[Table of Contents](/Docs#docs)_ diff --git a/Docs/5c_DatabaseMigrations.md b/Docs/5c_DatabaseMigrations.md deleted file mode 100644 index e49b9f21..00000000 --- a/Docs/5c_DatabaseMigrations.md +++ /dev/null @@ -1,187 +0,0 @@ -# Database: Migrations - -- [Creating a migration](#creating-a-migration) -- [Implementing Migrations](#implementing-migrations) -- [Schema functions](#schema-functions) -- [Creating a table](#creating-a-table) - * [Adding Columns](#adding-columns) - * [Adding Indexes](#adding-indexes) -- [Altering a Table](#altering-a-table) -- [Other schema functions](#other-schema-functions) -- [Running a Migration](#running-a-migration) - * [Via Command](#via-command) - + [Applying](#applying) - + [Rolling Back](#rolling-back) - * [Via Code](#via-code) - + [Applying](#applying-1) - + [Rolling Back](#rolling-back-1) - -Migrations are a key part of working with an SQL database.

With Rune, each database table has a corresponding `Model` type that is used to interact with that table. Use this Model type for querying, inserting, updating or deleting from the table. - -## Creating a Model - -To get started, implement the Model protocol. All it requires is an `id` property. Each property of your `Model` will correspond to a table column with the same name, converted to `snake_case`. - -```swift -struct User: Model { - var id: Int? // column `id` - let firstName: String // column `first_name` - let lastName: String // column `last_name` - let age: Int // column `age` -} -``` - -**Warning**: `Model` APIs rely heavily on Swift's `Codable`. Please avoid overriding the compiler synthesized `func encode(to: Encoder)` and `init(from: Decoder)` functions. You might be able to get away with it but it could cause issues under the hood. You _can_ however, add custom `CodingKeys` if you like, just be aware of the impact it will have on the `keyMappingStrategy` described below. - -## Custom Table Names - -By default, your model will correspond to a table with the name of your model type, pluralized. For custom table names, you can override the static `tableName: String` property. - -```swift -// Corresponds to table name `users`. -struct User: Model {} - -struct Todo: Model { - static let tableName = "todo_table" -} -``` - -### Custom Key Mappings - -As mentioned, by default all `Model` property names will be converted to `snake_case`, when mapping to corresponding table columns. You may change this behavior via the `keyMapping: DatabaseKeyMapping`. You could set it to `.useDefaultKeys` to use the verbatim `CodingKey`s of the `Model` object, or `.custom((String) -> String)` to provide a custom mapping closure. - -```swift -struct User: Model { - static let keyMapping = .useDefaultKeys - - var id: Int? // column `id` - let firstName: String // column `firstName` - let lastName: String // column `lastName` - let age: Int // column `age` -} -``` - -## Model Field Types - -### Basic Types - -Models support most basic Swift types such as `String`, `Bool`, `Int`, `Double`, `UUID`, `Date`. Under the hood, these are mapped to relevant types on the concrete `Database` you are using. - -### Advanced Types - -Models also support some more advanced Swift types, such as `enum`s and `JSON`. - -#### Enums - -`String` or `Int` backed Swift `enum`s are allowed as fields on a `Model`, as long as they conform to `ModelEnum`. - -```swift -struct Todo: Model { - enum Priority: String, ModelEnum { - case low, medium, high - } - - var id: Int? - let name: String - let isComplete: Bool - let priority: Priority -} -``` - -#### JSON - -Models require all properties to be `Codable`, so any property that isn't one of the types listed above will be stored as `JSON`. - -```swift -struct Todo: Model { - struct TodoMetadata: Codable { - var createdAt: Date - var lastUpdated: Date - var colorName: String - var comment: String - } - - var id: Int? - - let name: String - let isDone: Bool - let metadata: TodoMetadata // will be stored as JSON -} -``` - -#### Custom JSON Encoders - -By default, `JSON` properties are encoded using a default `JSONEncoder()` and stored in the table column.

You can schedule code or jobs from the `scheudle()` method of your `Application` instance. ```swift -// Say good morning every day at 9:00 am. -app.schedule { print("Good morning!") } - .daily(hour: 9) +@main +struct MyApp: Application { + ... -// Run `SendInvoices` job on the first of every month at 9:30 am. -app.schedule(job: SendInvoices()) - .monthly(day: 1, hour: 9, min: 30) + func schedule(schedule: Scheduler) { + // Say good morning every day at 9:00 am. + schedule.run { print("Good morning!") } + .daily(hour: 9) + + // Run `SendInvoices` job on the first of every month at 9:30 am. + schedule.job(SendInvoices()) + .monthly(day: 1, hour: 9, min: 30) + } +} ``` A variety of builder functions are offered to customize your schedule frequency. If your desired frequency is complex, you can even schedule a task using a cron expression. ```swift // Every week on tuesday at 8:00 pm -app.schedule { ... } +schedule.run { ... } .weekly(day: .tue, hour: 20) // Every second -app.schedule { ... } +schedule.run { ... } .secondly() // Every minute at 30 seconds -app.schedule { ... } +schedule.run { ... } .minutely(sec: 30) -// At 22:00 on every day-of-week from Monday through Friday.” -app.schedule { ... } +// At 22:00 on every day from Monday through Friday.” +schedule.run { ... } .cron("0 22 * * 1-5") ``` ## ...and more! -Check out [the docs](Docs#docs) for more advanced guides on all of the above as well as [Migrations](Docs/5c_DatabaseMigrations.md), [Caching](Docs/9_Cache.md), [Custom Commands](Docs/13_Commands.md), [Logging](Docs/10_DiggingDeeper.md#logging), [making HTTP Requests](Docs/10_DiggingDeeper.md#making-http-requests), using the [HTML DSL](Docs/10_DiggingDeeper.md#plot--html-dsl), [advanced Request / Response usage](Docs/3a_RoutingBasics.md#responseencodable), [sharing API interfaces](Docs/4_Papyrus.md) between client and server, [deploying your apps to Linux or Docker](Docs/11_Deploying.md), and more. +Check out [the docs](https://www.alchemyswift.com/getting-started/setup) for more advanced guides on all of the above as well as [Migrations](https://www.alchemyswift.com/database/migrations), [Caching](https://www.alchemyswift.com/digging-deeper/cache), [Custom Commands](https://www.alchemyswift.com/digging-deeper/commands), [Logging](https://www.alchemyswift.com/essentials/logging), [making HTTP Requests](https://www.alchemyswift.com/digging-deeper/http-client), using the [HTML DSL](https://www.alchemyswift.com/essentials/views), advanced [Request](https://www.alchemyswift.com/essentials/requests) / [Response](https://www.alchemyswift.com/essentials/responses) usage, [typesafe APIs](https://www.alchemyswift.com/supporting-libraries/papyrus) between client and server, [deploying your apps to Linux or Docker](https://www.alchemyswift.com/getting-started/deploying), and more. # Contributing diff --git a/Sources/Alchemy/Commands/Make/MakeController.swift b/Sources/Alchemy/Commands/Make/MakeController.swift index 47df04fb..f24a311c 100644 --- a/Sources/Alchemy/Commands/Make/MakeController.swift +++ b/Sources/Alchemy/Commands/Make/MakeController.swift @@ -62,7 +62,7 @@ struct MakeController: Command { } private func create(req: Request) async throws -> \(name) { - try await req.decodeBodyJSON(as: \(name).self).insertReturn() + try await req.decode(\(name).self).insertReturn() } private func show(req: Request) async throws -> \(name) { @@ -70,7 +70,7 @@ struct MakeController: Command { } private func update(req: Request) async throws -> \(name) { - try await \(name).update(req.parameter("id"), with: req.decodeBodyDict() ??
