auto set timestamp column when update & insert #854

PR Info

Closes Automatically update created_at & updated_at timestamp columns on update #827

Adds

add created_at & updated_at attributes support when define model

More Details

In this implement, the timestamp column type should be defined as TIMESTAMP or TIMESTAMPTZ, so the Model must be defined line below

#[derive(Clone, Debug, PartialEq, DeriveEntityModel)]
#[sea_orm(table_name = "cake")]
pub struct Model {
    #[sea_orm(primary_key)]
    pub id: i64,
    #[sea_orm(default_value = "Sam")]
    pub name: String,
    #[sea_orm(created_at, column_type = "TimestampWithTimeZone")]
    pub created_at: DateTimeWithTimeZone,
    #[sea_orm(updated_at, column_type = "Timestamp")]
    pub updated_at: DateTime
}

Hey @liberwang1013, sorry for the delay. Thanks for the contributions!!

I have added some test cases, refactored a few places as well. Please review and then cherrypick :)

Hi @billy1624 , thank you for your commit. I have already cherrypicked your commit, your commit is great. But, now we have to face a new problem that we didn't pass all checks. I have searched some documents try to figure out what's the problem . In this case, it seems that default value the system given is conflicted with msyql default sql_mode setttings.

CREATE TABLE `check` (
  `id` int NOT NULL AUTO_INCREMENT PRIMARY KEY,
  `pay` varchar(255) NOT NULL,
  `amount` double NOT NULL,
  `updated_at` timestamp NOT NULL,
  `created_at` timestamp NOT NULL
)

I think there are three ways to fix it

remove the NOT NULL constrain for updated_at & created_at columns
give the default value CURRENT_TIMESTAMP for updated_at & created_at columns
disable NO_ZERO_DATE sql mode in this case

what's your opinion?

tyt2y3 · 2022-08-07T10:02:58Z

Yes, actually if you want a robust timestamps, the best way is to rely on DB's native DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP. And I think we need better SeaQuery support for this

Note that not all database support such ON UPDATE CURRENT_TIMESTAMP syntax. For example, PostgreSQL doesn't have it. Instead, a trigger is needed to perform the operation. See https://stackoverflow.com/a/1036010/7059723

billy1624 · 2022-08-10T10:51:58Z

Okay, we have two problems here

Define timestamp column with default value of CURRENT_TIMESTAMP

#[derive(Clone, Debug, PartialEq, DeriveEntityModel)]
#[sea_orm(table_name = "check")]
pub struct Model {
    ...
    #[sea_orm(updated_at, default_expr = "Func::current_timestamp()")]
    pub updated_at: DateTimeWithTimeZone,
    #[sea_orm(created_at, default_expr = "Func::current_timestamp()")]
    pub created_at: DateTimeWithTimeZone,
}

Also, we could provide a shorthand for it

#[derive(Clone, Debug, PartialEq, DeriveEntityModel)]
#[sea_orm(table_name = "check")]
pub struct Model {
    ...
    #[sea_orm(updated_at, default_current_timestamp)]
    pub updated_at: DateTimeWithTimeZone,
    #[sea_orm(created_at, default_current_timestamp)]
    pub created_at: DateTimeWithTimeZone,
}

#[derive(Clone, Debug, PartialEq, DeriveEntityModel)]

pub struct Model {
    ...
    #[sea_orm(updated_at, default_expr = "Func::current_timestamp()")]
    pub updated_at: DateTimeWithTimeZone,
    #[sea_orm(created_at, default_expr = "Func::current_timestamp()")]
    pub created_at: DateTimeWithTimeZone,
}

In this way, I prefer using CURRENT_TIMESTAMP directly. In some cases, the developer can use some sea-orm still unsupported expresssion such as Generated Columns features.

Okay, we have two problems here

1. Define timestamp column with default value of `CURRENT_TIMESTAMP`

#[derive(Clone, Debug, PartialEq, DeriveEntityModel)]
#[sea_orm(table_name = "check")]
pub struct Model {
    ...
    #[sea_orm(updated_at, default_expr = "Func::current_timestamp()")]

I'd say the extra attribute is good to have and it serve as a temporary workaround before default expression land. :)

https://docs.rs/sea-query/latest/sea_query/table/struct.ColumnDef.html#method.default in SeaQuery now also accpets an Expr so we can now write:

let table = Table::create()
    .table(Char::Table)
    .col(ColumnDef::new(Char::FontId).integer().default(12i32))
    .col(
        ColumnDef::new(Char::CreatedAt)
            .timestamp()
            .default(Expr::current_timestamp())
            .not_null(),
    )
    .to_owned();

assert_eq!(
    table.to_string(MysqlQueryBuilder),
    [
        "CREATE TABLE `character` (",
        "`font_id` int DEFAULT 12,",
        "`created_at` timestamp DEFAULT CURRENT_TIMESTAMP NOT NULL",
        ")",
    ]
    .join(" ")
);

src/schema/entity.rs

+    if let Some(value) = orm_column_def.extra {
+        column_def.default(value);
+    }


Found a typo

Suggested change

if let Some(value) = orm_column_def.extra {

column_def.default(value);

}

if let Some(value) = orm_column_def.extra {

column_def.extra(value);

}

Hi @billy1624 thanks for your comment,
what about replaced with column_def.default(SimpleExpr::CustomWithExpr(value, vec![]));, I found the generated default expr in schema is going to quoted with ' in this(column_def.default(value);) way.

Any updates on this functionality getting in, or has something else similar made its way into the crate?
