About this deal
flash ( '"{}" was successfully deleted!' . format (post [ 'title' ] ) ) return redirect (url_for ( 'index' ) ) Inside the function, you use the get_db_connection() function to open a database connection and execute a SQL query to get the blog post associated with the given post_id value. You add the fetchone() method to get the result and store it in the post variable then close the connection. 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.
The value of the post title input is {{ request.form['title'] }} and the text area has the value {{ request.form['content'] }}, this is done so that the data you enter does not get lost if something goes wrong. For example, if you write a long post and you forget to give it a title, a message will be displayed informing you that the title is required. This will happen without losing the post you wrote since it will be stored in the request global object that you have access to in your templates. Once the file finishes execution, a new file called database.db will appear in your flask_blog directory. This means you’ve successfully set up your database.

A local Python 3 programming environment, follow the tutorial for your distribution in How To Install and Set Up a Local Programming Environment for Python 3 series for your local machine. In this tutorial we’ll call our project directory flask_blog. Save and close the file. The navigation bar will now have a New Post item that links to the /create route. Editing a PostNow that you’ve finished displaying the blog posts that are present in the database on the web application, you need to allow the users of your application to write new blog posts and add them to the database, edit the existing ones, and delete unnecessary blog posts. Creating a New Post For testing the work, we decided to go with AWS instances — the cloud proves to be the most economical and the least time consuming choice when the requirement is make-test-and-break kind of setups. As you go ahead and read, you can see the value in this decision. We did multiple setups for testing which you will see as you read further. Active Directory Topology However you can access this route via a form that sends a POST request passing in the ID of the post you want to delete. The function will receive the ID value and use it to get the post from the database with the get_post() function. cur .execute ( "INSERT INTO posts (title, content) VALUES (?, ?)" , ( 'First Post' , 'Content for the first post' ) ) First, because data in SQLite is stored in tables and columns, and since your data mainly consists of blog posts, you first need to create a table called posts with the necessary columns. You’ll create a .sql file that contains SQL commands to create the posts table with a few columns. You’ll then use this file to create the database.
Here is the complete error, i have played around with some of the other tabs on this Github, techwithtim- flask web app tutorial around this issue and have not found success being able to sign up a new user. flask_blog/app.py # .... @app .route ( '//delete' , methods = ( 'POST' , ) ) def delete ( id ) : Reusable water bottles come in various shapes, sizes, and materials. However, they also come in various capacities. You can find smaller, handbag-sized 250ml bottles, as well as standard 500ml bottles and gym-size 2.2-litre mammoths. Consider where you want to take your bottle with you and your ideal capacity before you buy. url_for('index')}}: A function call that will return the URL for the index() view function. This is different from the past url_for() call you used to link a static CSS file, because it only takes one argument, which is the view function’s name, and links to the route associated with the function instead of a static file. Here, you pass 'post' to the url_for() function as a first argument. This is the name of the post() view function and since it accepts a post_id argument, you give it the value post['id']. The url_for() function will return the proper URL for each post based on its ID.
