$ flask db upgrade  # Needs to be executed at each DB Schema Update

Start the project

$ flask run

How it works

The Dynamic API tool aims to enable a secured API service on top of any Flask codebase with a minimum effort. Here are the steps:

• Define a new model in the project (an old one can be also used)
• Execute the database migration to create/update the associated tables
• Update the configuration to enable the Dynamic API over the model
• Start the app
• Access the Dynamic API Service

For instance, if the new model managed by the Dynamic API is called books, the associate API is exposed at /api/books/

Status	Item	info
✅	New Models Definition in apps/models	-
✅	The app is saved in apps/dyn_api	-
✅	Models enabled in apps/config.py via DYNAMIC_API variable	-
✅	The project exposes automatically a CRUD API over the new model	-
✅	Path of the service: /api/books/	In case the new model is Books
✅	The API is powered via Flask-RestX using best practices	-

API Permissions

Before using the API, the user must make a request to the `/login' endpoint and send his username and password.:

POST /login
{
  "username": "my_username",
  "password": "my_password"
}

The server returns a token if approved.

{
  "token": "RETURNED_TOKEN"
}

To use the features, the user must add a key and value to the headers.

headers of requests:

{
  ...
  "Authorization": "token RETURNED_TOKEN"
  ...
}

Note: token will be expired after 24 hours.
