You can use the MVC pattern in your Flask application using this extension.

Run the follow command to install mvc_flask:

$ pip install mvc_flask

To start the mvc_flask you need to import and register in your application.

from flask import Flask
from mvc_flask import FlaskMVC

app = Flask(__name__)
FlaskMVC(app)

Or use application factories, e.g:

mvc = FlaskMVC()

def create_app():
  ...
  mvc.init_app(app)

By default the mvc_flask assumes that your application directory will be app and if it doesn't exist, create it! If you can use other directories, you can use the path parameter when the instance of FlaskMVC is initialized. E.g:

mvc = FlaskMVC()

def create_app():
  ...
  mvc.init_app(app, path='src')

Now, you can use src as default directory for prepare your application.

You structure should be look like this:

app
├── __ini__.py
├── controllers
│   └── home_controller.py
├── routes.py
└── views
    ├── index.html
