Product Information

You can now interact with the new questions model in your questions blueprint. To do so, open the questions blueprint’s routes.py file for a modification to query and display the questions you have in your questions table: In this step, you’ll create a configuration file for your Flask application, separating your application settings from the rest of the application and making changing settings easier. The configuration file will configure things such as the secret key, the SQLAlchemy database URI, and so on. You will use this db object to integrate SQLAlchemy with the Flask application you construct in your factory function. Open your app/__init__.py file to edit the factory function:

With your programming environment activated and Flask installed, open a file called app.py for editing inside your flask_app directory: Next, create a new categories.html file inside the posts directory. This is the file you rendered in the categories() view function of the posts blueprint: Multi-wall insulation: Double-wall insulation creates a vacuumed layer, which is vital for keeping hot drinks hot and cold drinks cold. Some flasks include more layers for even better insulation. The 100% stainless steel construction of today’s flasks means there’s no risk of inner walls shattering when dropped.main .route ( '/profile' ) @login_required def profile ( ) : return render_template ( 'profile.html' , name =current_user .name )

These commands will apply the modifications you make to your models and will delete all the existing data in the database. To update the database and preserve existing data, you’ll need to use schema migration, which allows you to modify your tables and preserve data. You can use the Flask-Migrate extension to perform SQLAlchemy schema migrations through the Flask command-line interface. It’s 100% leak proof – no matter how hard we tried, we couldn’t get any liquid to escape and the automatic opening trigger means you can drink from it one-handed with ease. Finally, there’s an additional loop handle on top so it can easily be attached to bags or simply carried this way. All in all, this is brilliantly stylish and robust If the post variable has the value None, meaning no result was found in the database, you use the abort() function you imported earlier to respond with a 404 error code and the function will finish execution. If, however, a post was found, you return the value of the post variable. Now that you have Flask available, you can create a simple application. Flask is a microframework. It does not include many of the tools that more full-featured frameworks might, and exists mainly as a module that you can import into your projects to assist you in initializing a web application.This will install a local copy of Python and pip into a directory called myprojectenv within your project directory. Your application is now written with an entry point established. You can now move on to configuring Gunicorn.
