In order to upload the table declared in our "Model.py" we need a migration script. This command requires an attached message whenever it runs, for instance:

`flask db migrate -m` "`first migration`"

In this case, the terminal should print in return `Detected added table user`, among others. We can now upload the migration script.

We can test our application using Postman. Paste the main path on a new Postman tab, for instance:

http://127.0.0.1:5000/user

Our table is empty for the moment, so we will select the POST method to add new data. We can submit JSON requests by clicking on the "Body" tab and selecting "raw". For example, submit:


{ "name" : "elena", "age" : 26, "phone" : "555123", "email" : "[email protected]" }


Our new user should now be accessible from the database under "id" number 1. Check this by submitting a GET request to the following path:

http://127.0.0.1:5000/user/1

We will now edit our entry by sending a PUT request. Submit the following body to http://127.0.0.1:5000/user/1:

{ "phone" : "777123" }

Now send another GET request and check whether the column was properly updated.

Lastly, you can check the DELETE method by sending this request to http://127.0.0.1:5000/user/1. Then send a GET request to http://127.0.0.1:5000/user. The application returns "User list is empty".

= Create a CRUD Python Flask application using CobiGen's OpenAPI plugin
====
The aim of this tutorial is to create a basic CRUD Python Flask application from a single OpenAPI .yml file declaring an entity.

The code will be generated using devonfw's CobiGen. This will result in a basic application layout, the declaration of a Flask-SQLAlchemy table with the entity's attributes as columns, and a service returning JSON objects for the GET, POST, PUT and DELETE methods.
