module AbstractController::Callbacks::ClassMethods
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/abstract_controller/callbacks.rb, line 91 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 :if
and :unless
options of ActiveSupport::Callbacks.
The basic idea is that :only => :index
gets converted to :if => proc {|c| c.action_name == "index" }
.
Note that :only
has priority over :if
in case they are used together.
only: :index, if: -> { true } # the :if option will be ignored.
Note that :if
has priority over :except
in case they are used together.
except: :index, if: -> { true } # the :except option will be ignored.
Options¶ ↑
-
only
- The callback should be run only for this action. -
except
- The callback should be run for all actions except this action.
