_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.
