It’s the “modern” way to handle authentication on the web. OpenID Connect is an open protocol that handles user authentication and authorization.

Flask-OIDC - an OpenID Connect library for Flask.

In this tutorial, we’ll be using SQLite as our database, but any of the others would work equally well with no code changes. It allows you to interact with relational database servers like Postgres, MySQL, SQLite, etc.

Flask-SQLAlchemy - an extremely popular ORM for Flask.

Flask - my favorite Python web framework.

Through this post you’ll learn about and use the following tools:

FLASK SQLITE HOW TO

By the end of this tutorial, you’ll know how to build simple Flask web apps and have a good understanding of how to create database models, add user registration and login to your sites, etc. In this post I’ll walk you through the code piece-by-piece, explaining everything you need to know along the way. Now the webapp should also show the list of logged users.Today I’m going to walk you through building a simple Flask web app (a blog) complete with user management (login, registration, etc.), database models, and everything else that goes along with it. If you complete and submit the form, the results will be also reflected in the terminal (pay attention at the POST method): * Running on (Press CTRL+C to quit)ġ27.0.0.1 - 'POST / HTTP/1.1' 200. Open your browser and visit 0.0.0.0:5000 (or 127.0.0.1:5000), the html will render and show up the login form. Output : * Running on (Press CTRL+C to quit)

To run the Flask app (server) type into your terminal: python main.py

All together: Testing and explaining data's flow Note: The host parameter can be changed to 127.0.0.1 (localhost) instead of 0.0.0.0. The Database Handler (models.py) methods are called when main.py has to acces and/or modify the database: dbHandler.insertUser(username, password), users = dbHandler.retrieveUsers(). This app makes database calls in order to insert new users and to return the logged users list requested by the POST method. Return render_template( 'index.html', users = users)Īpp.

route( '/', methods =) def home():ĭbHandler. In the case of a POST request (created after the form submission) it returns the list of logged users.įrom flask import Flask from flask import render_template from flask import request import models as dbHandler app = Flask( app. If the HTTP request is GET, the app returns the HTML form. This application works with a single flask function/route/url (views for convention) which answers to two types of HTTP methods (GET, POST). Flask Appįlask is a python microframework intended for the developement of web applications (server side). The html contains a simple html form with two text type inputs: username and password, and a submit type input (Login button). It uses the Flask template engine to render the 'logged users' list. The html code used for this app can be found in index.html file (in this same git). We'll later call these methods from main.py to handle the database.
