Now that you’ve created a blueprint and added a route, you’ll need to tell Flask about this new blueprint so that it can be treated as part of your Flask application. To do this, you’ll register the blueprint inside your Flask application factory function. This tutorial could be a bit better. For example there’s no automation. No explanation of what’s in proxy_params. I made a comment about removing it because I had added in redundant proxy headers. Leave /logout alone for now because it will not display a template later. Step 5 — Creating User Models

In the index route, you render a template file with the path posts/index.html which means that Flask will look for a directory called posts in the templates directory and then look for an index.html file inside of the posts directory. Create the questions directory inside the templates directory, and then open an index.html file in it:Next, create a symbolic link to the newly installed /snap/bin/certbot executable from the /usr/bin/ directory. This will ensure that the certbot command can run correctly on your server: With the views.py file in place, you’re ready to create the uwsgi.ini file. This file will contain the uWSGI configurations for our application. uWSGI is a deployment option for Nginx that is both a protocol and an application server; the application server can serve uWSGI, FastCGI, and HTTP protocols. If you stop your app and open up a Python REPL, you can create the database using the create_all method on the db object: You built a small Flask web application for managing todos that communicates with a MongoDB database. You learned how to connect to a MongoDB database server, create collections that store a group of documents, insert data to a collection, and retrieve and delete data from a collection. In this schema file, you first delete the posts table if it already exists. This avoids the possibility of another table named posts existing, which might result in confusing behavior (for example, if it has different columns). This isn’t the case here, because you haven’t created the table yet, so the SQL command won’t be executed. Note that this will delete all of the existing data whenever you execute this schema file. For our purposes, you will only execute this schema once, but you might want to execute it again to delete whatever data you inserted and start with an empty database again.

Your application is now written with an entry point established and you can proceed to configuring Gunicorn. Before installing applications within the virtual environment, you need to activate it by running the following: db .init_app (app ) # blueprint for auth routes in our app from .auth import auth as auth_blueprint The author selected the Tech Education Fund to receive a donation as part of the Write for DOnations program. IntroductionYou then add the post object to the database session, print the object itself and its content, and commit the transaction.
