Instance Method Summary

Instance Method Details

#_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

def _insert_callbacks(callbacks, block = nil)
  options = callbacks.extract_options!
  _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

    #skip_action_callback(*names)  
    Also known as: #skip_filter
  



  

    

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



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_action_callback
