Flask uses the MVC (Model View Controller) Framework. Just to make this as obvious as possible, I like my Flask apps to have the following.

• Model -> models.py
• View -> views.py
• Controller -> __init__.py

For example, let say you have the following.

├── main.py
├── my-project (directory)
│   ├── __init__.py
│   ├── views.py
│   ├── templates (directory)
│   │   ├── base.html
│   │   ├── home.html
│   │   ├── foo.html
│   │   ├── bar.html

redirect can be used to redirect a user.

• Redirect to a URL (such as http://www.example.com) (this article)
• Redirect to an HTML page using render_template
• Redirect to a Route using url_for

Here is an example of how you could use redirect. In this example, when requesting the /foo endpoint there will be an immediate redirect to the /bar endpoint.

from flask import Blueprint, render_template, redirect, url_for

views = Blueprint('views', __name__)

@views.route('/foo')
def home():
    return redirect('/bar')

@views.route('/bar')
def bar():
    return render_template('bar.html')

Or, you could redirect to some other URL.

from flask import Blueprint, render_template, redirect, url_for

views = Blueprint('views', __name__)

@views.route('/foo')
def home():
    return redirect('http://www.example.com')
