A simple e-commerce web application
-
A user should be able to register an account on our site using his/her email address and a password.
-
A user can do 3 things on the site: browse available items, buy an item, or sell an item. A user has a view of all pending/completed buy requests and sell requests he made, and modify their status.
-
To buy/sell an item, the user will be required to login. To view available items, a user is not required to login.
-
To buy an item, user need to provide his/her credit card number. For simplicity, we’ll implement a credit card validator.
-
To sell an item, user need to:
-
Take 3 pictures of the item from 3 different angles, provide user’s address.
-
Once the administrator approve the pictures, user’s item can be viewed among the available listings.
-
If the item is bought, user will be notified via email and will be given 3 time slots on the next day during which time he/she wants our staff to collect and deliver the item.
-
-
A staff should have either one of the following roles: Administrator or Collector.
-
An Administrator is not allowed to buy or sell items. An Administrator can view all unapproved sell request and give them comments/approve them.
-
A Collector could modify the status of buy requests/sell requests assigned to him.
-
A (Sell)Request on our site has the following states: PENDING_APPROVAL or APPROVED.
-
An Item on our site has the following states: LISTED, BOUGHT, IN_DELIVERY, TRANSACTED
Reference: This wonderful Flask tutorial
/commerce_hub.py: Python script that runs the application.
/app: The Python package that hosts the applicaiton. In Python, a sub-directory that includes a __init__.py file is considered a package, and can be imported. When you import a package, the __init__.py executes and defines what symbols the package exposes to the outside world.
Splitting routes by access right:
1. Everyone could access: `/home`, `/register`, `/login`
2. Only logged in users: `/buy/{item-id}`, `/sell/new/`, `/monitor/view`, `/monitor/edit`
3. Only Administrator: `/admin/requests`
4. Only Collector: `/collect/assigned` and `/collect/completed`
