Implement API Endpoint to Create Comment on Blog Post

[myconpeter]

Implement an API endpoint for adding comments to a blog post. This endpoint allows authenticated users to post comments on a specific blog entry.

Endpoint Feature

• This endpoint enables authenticated users to create comments on a blog post.
• Restricted to valid blog post IDs and non-empty comment content.

Acceptance Criteria

• The endpoint should be accessible at POST /api/v1/blog/{post_id}/comment.
• The endpoint should accept HTTP POST requests.
• The endpoint should create a comment for the specified blog post ID with the provided content.
• The endpoint should return a 201 Created status code with a success message in the response body.

Request Example

POST /api/v1/blog/123/comment
Content-Type: application/json

{
  "content": "This is a test comment."
}

Response Example

On successful creation of the comment, the API should return a 201 Created status code. The response body should contain a success message:

{
  "status": "success",
  "status_code": 201,
  "message": "Comment created successfully."
}

Data Validation

• Input Validation:

  • Confirm that content is provided and is not empty.
  • Example: If content is invalid or missing, return a 400 status code with an error message.

  {
    "status": "unsuccessful",
    "status_code": 400,
    "message": "Comment content must be provided and cannot be empty."
  }

• Output Validation:

  • Ensure the response format is correct and includes appropriate status codes and messages.
  • If there is an error in creating the comment (e.g., invalid blog post ID, database issues), the API should return a 500 Internal Server Error status code with an appropriate message:

  {
    "status": "unsuccessful",
    "status_code": 500,
    "message": "Failed to create comment. Please try again later."
  }

Authentication and Authorization

• Authentication:

  • Verify that the user is authenticated before allowing access to the endpoint.
  • Example: Use middleware to check for a valid authentication token.

• Authorization:

  • Ensure that only authorized users can post comments.
  • Example: Check user roles or permissions to confirm authorization.

Error Handling

• Error Responses:

  • Define error responses for common failure scenarios.
  • Example: If the blog post ID is invalid, return a 404 status code with an error message.

  {
    "status": "unsuccessful",
    "status_code": 404,
    "message": "Blog post not found."
  }

• Edge Cases:

  • Consider edge cases such as empty comment content or non-existent blog post ID.
  • Example: Handle scenarios where the specified blog post does not exist.

Performance and Security

• Performance Considerations:

  • Review potential performance implications and optimize the API for efficiency.
  • Example: Implement rate limiting to prevent abuse.

• Security Concerns:

  • Address security considerations such as data sanitization.
  • Example: Sanitize user inputs to prevent injection attacks.

Documentation

• API Documentation:
  • Ensure that API documentation is updated to include details about the new endpoint, request/response formats, error handling, and authentication requirements.

Technical Notes

• Include any additional technical notes or considerations.

Testing Requirements

• Unit Tests:

  • Write unit tests to validate input data and comment creation logic.

• Integration Tests:

  • Ensure end-to-end functionality is tested with integration tests.

Dependencies and Impact

• Dependencies:

  • Identify dependencies on other tasks or systems, such as user authentication.

• Impact Analysis:

  • Assess the potential impact on other features or components, ensuring that existing functionality is not disrupted.
