# CallbackAction

This gem gives you ability to add callbacks like `before_action` / `before_fitler` etc to your class.

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'callback_action'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install callback_action

## Usage

If you are using plain ruby:

```ruby
class Foobar
  extend ActionCallback

  before_action :foobar, on: [:foo, :bar]
  
  def foo
    # ...
  end

  def bar
    # ...
  end

  def foobar
    # ...
  end
end
```

If you are using Rails, you can save the `extend ActionCallback` line in active record models
(but you will still need that when you are defining a plain ruby class):

```ruby
class Foobar < ActiveRecord::Base
  before_action :foobar, on: [:foo, :bar]
  
  def foo
    # ...
  end

  def bar
    # ...
  end

  def foobar
    # ...
  end
end
```

### Available callbacks

Currently, you can use `before_action`, `after_action` to define callbacks.

#### `before_action` / `before_filter`

This will give you a before callback.

```ruby
before_action :before_callback, on: [:methods_that_will_invoke_before_callbacks]
```

#### `after_action` / `after_action`

This will give you a after callback.

```ruby
after_action :after_callback, on: [:methods_that_will_invoke_after_callbacks]
```
