_insert_callbacks(callbacks, block = nil)

Take callback names and an optional callback proc, normalize them, then call the block with each callback. This allows us to abstract the normalization across several methods that use it.

Parameters

  • callbacks- An array of callbacks, with an optional options hash as the last parameter.

  • block- A proc that should be added to the callbacks.

Block Parameters

  • name- The callback to be added

  • options- A hash of options to be used when adding the callback

# File actionpack/lib/abstract_controller/callbacks.rb, line 71
def _insert_callbacks(callbacks, block = nil)
  options = callbacks.last.is_a?(Hash) ? callbacks.pop : {}
  _normalize_callback_options(options)
  callbacks.push(block) if block
  callbacks.each do |callback|
    yield callback, options
  end
end
_normalize_callback_options(options)

If :only or :except are used, convert the options into the :unless and :if options of ActiveSupport::Callbacks. The basic idea is that :only => :index gets converted to :if => proc {|c| c.action_name == “index” }.

Options

  • only- The callback should be run only for this action

  • except- The callback should be run for all actions except this action

  _normalize_callback_option(options, :only, :if)
  _normalize_callback_option(options, :except, :unless)
end
after_action(names, block)

Append a callback after actions. See #_insert_callbacks for parameter details. Aliased as after_filter.

# File actionpack/lib/abstract_controller/callbacks.rb, line 120
      
append_after_action(names, block)

Append a callback after actions. See #_insert_callbacks for parameter details. Aliased as append_after_filter.

# File actionpack/lib/abstract_controller/callbacks.rb, line 144
      
append_around_action(names, block)

Append a callback around actions. See #_insert_callbacks for parameter details. Aliased as append_around_filter.

# File actionpack/lib/abstract_controller/callbacks.rb, line 176
      
append_before_action(names, block)

Append a callback before actions. See #_insert_callbacks for parameter details. Aliased as append_before_filter.

# File actionpack/lib/abstract_controller/callbacks.rb, line 112
      
around_action(names, block)

Append a callback around actions. See #_insert_callbacks for parameter details. Aliased as around_filter.

# File actionpack/lib/abstract_controller/callbacks.rb, line 152
      
before_action(names, block)

Append a callback before actions. See #_insert_callbacks for parameter details. Aliased as before_filter.

# File actionpack/lib/abstract_controller/callbacks.rb, line 88
      
prepend_after_action(names, block)

Prepend a callback after actions. See #_insert_callbacks for parameter details. Aliased as prepend_after_filter.

# File actionpack/lib/abstract_controller/callbacks.rb, line 128
      
prepend_around_action(names, block)

Prepend a callback around actions. See #_insert_callbacks for parameter details. Aliased as prepend_around_filter.

# File actionpack/lib/abstract_controller/callbacks.rb, line 160
      
prepend_before_action(names, block)

Prepend a callback before actions. See #_insert_callbacks for parameter details. Aliased as prepend_before_filter.

# File actionpack/lib/abstract_controller/callbacks.rb, line 96
      
skip_action_callback(*names)

Skip before, after, and around action callbacks matching any of the names Aliased as skip_filter.

Parameters

  • names- A list of valid names that could be used for callbacks. Note that skipping uses Ruby equality, so it's impossible to skip a callback defined using an anonymous proc using skip_filter

Also aliased as: skip_filter
# File actionpack/lib/abstract_controller/callbacks.rb, line 51
def skip_action_callback(*names)
  skip_before_action(*names)
  skip_after_action(*names)
  skip_around_action(*names)
end
skip_after_action(names)

Skip a callback after actions. See #_insert_callbacks for parameter details. Aliased as skip_after_filter.

# File actionpack/lib/abstract_controller/callbacks.rb, line 136
      
skip_around_action(names)

Skip a callback around actions. See #_insert_callbacks for parameter details. Aliased as skip_around_filter.

# File actionpack/lib/abstract_controller/callbacks.rb, line 168
      
skip_before_action(names)

Skip a callback before actions. See #_insert_callbacks for parameter details. Aliased as skip_before_filter.
