Question

In my ROR project I have a controller in which I want to always catch exceptions to do some cleanup before the error is propagated back up to the caller. Can this be done in ROR? I want a hook that will be called when any exception is encountered in the controller.

Answer 1

You can use rescue_from:

  class WhateverController < ApplicationController
      rescue_from Exception do |exception|
        # whatever handling here
      end

      # ...
    end
