How do I handle exceptions in Ruby on Rails?

In Ruby on Rails, you can handle exceptions using the rescue_from method in your controllers. This allows you to define how to respond to specific exceptions.

Can you give me an example of using rescue_from?

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

What if I want to log the exceptions as well?

You can log exceptions by adding a logging statement in your rescue method. For example, in record_not_found, you can use Rails.logger.error('Record not found') before rendering a response.

Is there a way to handle exceptions globally?

Yes, you can create a custom error handling middleware or use the ApplicationController to handle exceptions globally by overriding the rescue_from method.
