The User-Task Relationship

The video tutorial explains how to ensure that when a user deletes their profile, their associated tasks are also removed from the database. It discusses two approaches: adding code to the user deletion route or using middleware. The tutorial opts for middleware, demonstrating how to set it up in the user model using Mongoose. The process involves creating an async function to delete tasks based on the owner field. The tutorial concludes with testing the implementation using Postman and Robo 3T, confirming that tasks are correctly deleted when a user is removed.

What is the main issue addressed in the video regarding user deletion?

• Users cannot delete their profiles.

• Tasks remain in the database after a user deletes their profile.

• Users can delete other users' profiles.

• Tasks are automatically deleted when a user logs out.

Why is middleware preferred over modifying the delete route for task deletion?

• Middleware is faster than modifying the delete route.

• Middleware allows for task deletion in multiple parts of the application.

• Middleware is the only way to delete tasks.

• Middleware is easier to write.

What method is used in the middleware to delete multiple tasks?

• findAndDelete

• deleteMany

• remove

• deleteOne

What is the purpose of using 'await' in the middleware function?

• To handle asynchronous task deletion.

• To prevent errors in the code.

• To speed up the deletion process.

• To make the function synchronous.

How is the success of the middleware tested?

• By checking the console logs.

• By using Postman and Robo 3T to verify task deletion.

• By running automated tests.

• By manually deleting tasks from the database.

What happens when a user is deleted using Postman?

• The user is deactivated but not deleted.

• Only the user's profile is deleted.

• The user's tasks are archived.

• The user and their tasks are removed from the database.

What is the final outcome after implementing and testing the middleware?

• Tasks associated with a deleted user are also removed.

• Tasks are left in the database after user deletion.

• Users can no longer delete their profiles.

• The application crashes when a user is deleted.
