app . get ( '/login' ) def login_get (): return show_the_login_form () @app . post ( '/login' ) def login_post (): return do_the_login () If a DEBUG environment variable is set, drop tables and rebuild. Otherwise, just create the tables once and you're good to go. Views and URL config Move the static and templates folders into hello_app, because these folders certainly contain app code.

Introduction app = Flask (__name__ ) @app .route ( '/' ) def index ( ) : return render_template ( 'index.html' ) Then set the FLASK_ENV environment variable to development to run the application in development mode and get access to the debugger. For more information about the Flask debugger, see How To Handle Errors in a Flask Application. Use the following commands to do this (on Windows, use set instead of export):

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: Copy that line into the > prompt at the bottom of the debug console, and try changing the formatting: now.strftime( "%a, %d %B, %Y at %X" ) 'Wed, 31 October, 2018 at 18:13:39' now.strftime( "%a, %d %b, %Y at %X" ) 'Wed, 31 Oct, 2018 at 18:13:39' now.strftime( "%a, %d %b, %y at %X" ) 'Wed, 31 Oct, 18 at 18:13:39'

In the example above, when the app is running and accessed at http://domainname/, a user will receive "Hello, World!" as a response. Connecting the database in Flask Now, whenever you start typing the snippet's prefix, such as flext, VS Code provides the snippet as an autocomplete option, as shown in the next section. You can also use the Insert Snippet command to choose a snippet from a menu. In this new view function, you add a variable rule to specify that the part after the slash ( /) is a positive integer (marked with the int converter) that you need to access in your view function. Flask recognizes this and passes its value to the post_id keyword argument of your post() view function. You then use the get_post() function to get the blog post associated with the specified ID and store the result in the post variable, which you pass to a post.html template that you’ll soon create. To better understand how a Django web app works, let’s consider four fundamental components of the app design pattern: I should've replied to this last month when you posted it. An unfinished version of all of it is available here: https://github.com/PythonToDoList/flask

The decorator used for the new URL route, /hello/, defines an endpoint /hello/ that can accept any additional value. The identifier inside < and > in the route defines a variable that is passed to the function and can be used in your code. Today, Django is maintained by the Django Software Foundation and is one of the most popular Python frameworks for web development. The first SQL command is DROP TABLE IF EXISTS posts;, this deletes any already existing tables named posts so you don’t get confusing behavior. Note that this will delete all of the content you have in the database whenever you use these SQL commands, so ensure you don’t write any important content in the web application until you finish this tutorial and experiment with the final result. Next, CREATE TABLE posts is used to create the posts table with the following columns:
