This enables a web frame to be built on it. The Flask framework uses Werkzeg as one of its bases. jinja2 After creating the Python list, you use the @app.route() decorator to create a view function called index(). In it, you return a call to the render_template() function, which indicates to Flask that the route should display an HTML template. You name this template index.html (you’ll create it later), and you pass a variable called messages to it. This variable holds the messages list you previously declared as a value and makes it available to the HTML template. View functions are covered in the tutorial How To Create Your First Web Application Using Flask and Python 3. Flask-Login: manages the user session and handles logging in and logging out and remembering logged-in users.In VS Code, open the Command Palette ( View> Command Palette or ( ⇧⌘P (Windows, Linux Ctrl+Shift+P))). Then select the Python: Create Environment command to create a virtual environment in your workspace. Select venv and then the Python environment you want to use to create it.

To successfully complete this Flask tutorial, you must do the following (which are the same steps as in the general Python tutorial):

This isn’t to say that there isn’t a large community of developers to answer questions when you run into a problem with your Flask application. But, the communities and documentation out there are a little smaller and harder to find compared to Django support resources. id: An integer that represents a primary key, this will get assigned a unique value by the database for each entry (that is a blog post). Flask is named after an earlier Python micro-framework called Bottle. It’s easily one of the most popular Python web-development frameworks, coming in just slightly behind Django in terms of the number of stars on GitHub.

Note: Once launch.json is created, an Add Configuration button appears in the editor. That button displays a list of additional configurations to add to the beginning of the configuration list. (The Run> Add Configuration menu command does the same action.).In your project folder, create a folder for the app, such as hello_app, to separate its files from other project-level files like requirements.txt and the .vscode folder where VS Code stores settings and debug configuration files.

NOT NULL signifies that this column should not be empty and the DEFAULT value is the CURRENT_TIMESTAMP value, which is the time at which the post was added to the database. Just like id, you don’t need to specify a value for this column, as it will be automatically filled in. flask_app/app.py # ... @app .route ( '/create/' , methods = ( 'GET' , 'POST' ) ) def create ( ) : return render_template ( 'create.html' )

During your work with Flask or any other library, you may want to examine the code in those libraries themselves. VS Code provides two convenient commands that navigate directly to the definitions of classes and other objects in any code: from flask import request @app . route ( '/login' , methods = [ 'GET' , 'POST' ]) def login (): if request . method == 'POST' : return do_the_login () else : return show_the_login_form () You close the database connection using the close() method and return the result of rendering the index.html template. You also pass the posts object as an argument, which contains the results you got from the database, this will allow you to access the blog posts in the index.html template. In this section, you will create a virtual environment in which Flask is installed. Using a virtual environment avoids installing Flask into a global Python environment and gives you exact control over the libraries used in an application.
