module Critic::Callbacks::ClassMethods
Adds callback management functions to {Critic::Policy}
Public Instance Methods
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 lib/critic/callbacks.rb, line 102 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
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
