Summaries of links found in the content:

https://flask-login.readthedocs.io/en/latest/#how-it-works:

The page is the documentation for Flask-Login, a library that provides user session management for Flask. It handles tasks such as logging in, logging out, and remembering user sessions. The page explains how to configure Flask-Login in your application and provides examples of how to use it.

To implement Flask-Login, you need to create a LoginManager object and configure it for your application. You can set the login view, customize the login process, and handle unauthorized and needs_refresh situations.

The page also provides information on how to create a user class that implements certain properties and methods required by Flask-Login. It explains how to log in a user, protect views that require authentication, and handle session protection.

There are code snippets throughout the page that demonstrate how to use Flask-Login in different scenarios, such as logging in a user, protecting views, and customizing the login process.

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: • Add a new function named load_user that takes user_id as an argument. This function should query the database for a user with the given user_id and return the user object if it exists. • Decorate the load_user function with @login_manager.user_loader to register it as a user loader function.

Step 3: 📝 Planning

I have created a plan for writing the pull request. I am now working my plan and coding the required changes to address this issue. Here is the planned pull request:

Implement user loader for Flask-Login sweep/implement-user-loader

Description

This PR implements a user loader function for Flask-Login in the main.py file. The user loader function is necessary for Flask-Login to reload the user object from the session.

Summary of Changes

Added a new function named load_user in main.py that takes a user_id as an argument.

The load_user function queries the database for a user with the given user_id and returns the user object if it exists.

Decorated the load_user function with @login_manager.user_loader to register it as a user loader function.

This PR addresses Issue #61.

Step 4: ⌨️ Coding

I have finished coding the issue. I am now reviewing it for completeness.

Step 5: 🔁 Code Review

Here are my self-reviews of my changes at sweep/implement-user-loader.

Here is the 1st review

No changes required. The user loader for Flask-Login has been correctly implemented. Just ensure that the User model has been correctly defined and that the 'id' field is indeed an integer. Also, the 'User' model and 'UserMixin' class should be properly imported. Good job!

I finished incorporating these changes.
