How can I handle errors in a Rails API?

In a Rails API, you can handle errors by using rescue_from in your controllers to catch exceptions and return appropriate responses.

Can you give me an example of using rescue_from?

Sure! You can add this to your controller: rescue_from ActiveRecord::RecordNotFound, with: :record_not_found. Then define the method to handle the error.

What should the record_not_found method return?

The method can return a JSON response with a 404 status code, like this: render json: { error: 'Record not found' }, status: :not_found.

Is there a way to handle multiple types of errors?

Yes, you can chain multiple rescue_from calls or handle them in a single method by checking the type of error.
