(SP:2) Implement "Update Lesson" endpoint

[vlad-khrychov]

Description

This task is dedicated to developing the endpoint for updating existing lessons within our application. It involves setting up the route, crafting the controller and service logic, ensuring proper validation of request data, creating tests for the endpoint's functionality, and documenting the endpoint in Swagger.

Requirements:

• Route:

  • Define a new PATCH route /lessons/:id for updating lessons. This route should be accessible only to authenticated users with specific roles (e.g., Tutor or Admin) and should allow updates to specific lesson fields.

• Service Layer:

  • Develop a service function that receives the lesson ID and update data, validates the updates against our lesson model schema, checks for lesson ownership or permission, and then applies the updates to the database. Error handling for database operations and validation failures should be included.

• Controller:

  • Implement a controller function that handles the PATCH request. This function should retrieve the lesson ID from the route parameters, the update data from the request body, and then call the service layer for processing. It must handle errors and return appropriate HTTP response codes and messages.

• Tests:

  • Write tests covering the endpoint, including scenarios for successful updates, attempts to update non-existent lessons, invalid update data, and unauthorized access attempts.

• Swagger Documentation:

  • Update the Swagger documentation to include the "Update Lesson" endpoint, detailing the request path, body parameters, possible response codes, and descriptions of each.

• Error Handling:

  • Ensure robust error handling within the endpoint to manage and respond to errors effectively, providing clear feedback to the client.

• Security and Permissions:

  • Confirm that the endpoint verifies user authentication and authorizes only users with permissions to update the specific lesson.
