User Analysis Data Controller Implementation with Edge Case Handling

[IkkiOcean]

**Pull Request: **

Description:

This PR introduces the functionality for managing user analysis data in the application. It includes the creation of a UserAnalysis controller with methods for creating, retrieving, updating, and deleting user analysis data, as well as proper validation and error handling for edge cases.

Changes Made:

• UserAnalysis Controller:

  • createUserAnalysis: Handles creating new user analysis data with input validation for required fields (userId, activityLog, interactions, preferences).
  • getUserAnalysis: Retrieves user analysis data by ID with validation for the ID format and error handling for not found records.
  • updateUserAnalysis: Updates existing user analysis data by ID with validation for update fields, and checks if the user ID is valid.
  • deleteUserAnalysis (optional): Deletes user analysis data by ID, with validation to ensure the record exists before deletion.
  • getAllUserAnalysis (optional): Retrieves all user analysis data, with a check for an empty result set.

• Edge Case Handling:

  • Proper validation for required fields and ObjectId format.
  • Error handling for missing fields, invalid ObjectId format, and MongoDB errors (e.g., duplicate keys).
  • Handling for non-existent records during the retrieval or update operations.
  • Responses with appropriate HTTP status codes (200, 201, 400, 404, 409, 500).

Validation and Error Handling:

• The controller validates input fields to ensure that no essential data is missing during the create and update processes.
• If the userId or ID in the URL is invalid, the controller responds with a 400 Bad Request error.
• The controller also handles possible MongoDB errors such as duplicate entries (via error code 11000).
• 404 Not Found errors are returned when the requested data (user analysis) is not found in the database.
• General errors or unexpected issues are caught and result in a 500 Internal Server Error with detailed error messages.

How to Test:

• Create User Analysis:

  • Send a POST request to /user-analysis with valid JSON data (e.g., userId, activityLog, interactions, preferences). Check for a successful response with 201 Created.

• Retrieve User Analysis by ID:

  • Send a GET request to /user-analysis/{id} with a valid id. Ensure the response is the correct user analysis data with 200 OK.

• Update User Analysis by ID:

  • Send a PUT request to /user-analysis/{id} with the necessary fields for update. Verify that the response contains the updated data and returns 200 OK.

• Handle Invalid ObjectId:

  • Test with an invalid id in the URL to ensure a 400 Bad Request error is returned.

• Delete User Analysis:

  • Send a DELETE request to /user-analysis/{id} to ensure the data is properly deleted and a 200 OK response is returned.
