Step 2: 🧐 Snippet Analysis

From looking through the relevant snippets, I decided to make the following modifications:

File Path Proposed Changes

main.py Modify main.py with contents:
• In the login() function, add a check for if the request method is POST.
• If the request method is POST, retrieve the username and password from the form data.
• Validate these credentials against the database. If they are valid, use Flask-Login's login_user() function to log the user in and redirect them to the home page.
• If the credentials are not valid, flash an error message and render the login template again.
• In the signup() function, add a check for if the request method is POST.
• If the request method is POST, retrieve the username and password from the form data.
• Validate this input to ensure the username is not already taken and the password meets any necessary requirements.
• If the input is valid, create a new User object and add it to the database. Then log the user in and redirect them to the home page.
• If the input is not valid, flash an error message and render the signup template again.

Handle login and registration POST requests sweep/handle-login-registration-post-requests

Description

This PR addresses issue #15 and is a part of the parent issue #13. It updates the login() and signup() functions in main.py to handle POST requests, validate user input, and interact with the database.

Summary of Changes

Modified the login() function to handle POST requests. It now retrieves the username and password from the form data, validates these credentials against the database, and logs the user in if they are valid. If the credentials are not valid, it flashes an error message and renders the login template again.

Modified the signup() function to handle POST requests. It now retrieves the username and password from the form data, validates this input to ensure the username is not already taken and the password meets any necessary requirements. If the input is valid, it creates a new User object and adds it to the database, then logs the user in and redirects them to the home page. If the input is not valid, it flashes an error message and renders the signup template again.

Please review these changes and let me know if any further modifications are required.
