callback_skipper

Programatically Skip ActiveRecord Callbacks

Features

• easily skip callbacks
• useful for unit testing to skip long running processes

Installation

# Gemfile
gem 'callback_skipper'

Usage

class Foo < ActiveRecord::Base
  after_create :do_something_expensive
end

foo = Foo.new
foo.skip_callback :save, :after, :do_something_expensive
foo.save!

Error handling

If the code attempts to skip an undefined callback, a CallbackSkipper::CallbackNotDefinedError will be raised:

# class Foo is defined above
foo = Foo.new
begin
  foo.skip_callback :save ,:after, :method_that_is_not_defined
rescue CallbackSkipper::CallbackNotDefinedError
  puts "You should not skip callback methods that are not defined"
end

Example: FactoryGirl Usage

# spec/factories/foo_factory.rb
Factory.define :foo do |f|
  f.after_build do |o|
    o.skip_callback :save, :after, :do_something_expensive
  end
end
