MethodHooks

Allows you to add before, around, and after callbacks to any method.

Installation

Add this line to your application's Gemfile:

gem 'method_hooks'

And then execute:

$ bundle

Or install it yourself as:

$ gem install method_hooks

Usage

class Model
  extend MethodHooks

  before :save do
    puts 'before'
  end

  around :save do |method|
    puts 'before_around'
    method.call
    puts 'after_around'
  end

  after :save, :foo do
    puts 'after'
  end

  def save
    puts 'save'
  end

  def foo
    puts 'foo'
  end

end

model = Model.new
model.save
model.foo

=begin

Outputs the following:

before
before_around
save
after_around
after
foo
after

=end

You can also specify a method to be called instead of using a block:

class Model
  extend MethodHooks

  before :save, :my_method

  def save
    puts 'save'
  end

  private

  def my_method
    puts 'my_method'
  end

end

model = Model.new
model.save

=begin

Outputs the following:

my_method
save

=end
