How can I implement error handling in a Rails API?

You can implement error handling in a Rails API by using rescue_from in your controllers to catch exceptions.

Can you give me an example of how to use rescue_from?

Sure! You can add this to your ApplicationController: rescue_from ActiveRecord::RecordNotFound, with: :record_not_found.

What should the record_not_found method look like?

The method can render a JSON response like this: def record_not_found; render json: { error: 'Record not found' }, status: :not_found; end.

How do I handle validation errors in my API?

You can handle validation errors by using the valid? method and returning the errors in the response if validation fails.
