You can use the mvc pattern in your flask application using this extension.

Installation

Run the follow command to install mvc_flask:

$ pip install mvc_flask

Configuration

To configure the mvc_flask you need import and register in your application, e.g:

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!

You structure should be look like this:

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

Router

You can create routes in app/routes.py and after create file, you can start register routes, e.g:

from mvc_flask import Router

Router.get("/", "home#index")

The same must be make done to POST, PUT and DELETE methods. E.g: Router.post("/messages", "messages#create")

The first param represent the relative path and second represent the controller#action. Remember that we are working with MVC pattern, so we have controller and action.

The controller can be created in app/controllers and action is method of controller.

Controller

Now that configure routes, the home_controller.py file must contain the HomeController class, registering the action, e.g:

from flask import render_template

class HomeController:
    def index(self):
        return render_template("index.html")

If you have question, please, check de app directory to more details.

Views

Flask use the templates directory by default to store HTMLs files. However, using the mvc-flask the default becomes views. You can use the app/views directory to stores templates.

Tests

You can run the tests, executing the follow command:
