Flask Framework Cookbook - Second Edition

How to do it...

Let's demonstrate this with a small application. This application is very similar to the one we developed in Chapter 1, Flask Configurations.

The first thing to do is to add a new folder named templates under my_app. The application structure should look like the following directory structure:

flask_app/ 
    - run.py 
    my_app/ 
        - __init__.py 
        - hello/ 
            - __init__.py 
            - views.py

from flask import render_template, request @hello.route('/') @hello.route('/hello') def hello_world(): user = request.args.get('user', 'Shalabh') return render_template('index.html', user=user) ...
