_normalize_callback_options(options)public
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.
