Available in: v3.0.20 v3.1.12 v3.2.22.5 v4.0.13 v4.1.16 v4.2.9 v5.2.8.1 v6.0.6 v6.1.7.10 v7.0.10 v7.1.6 v7.2.3 v8.0.4 v8.1.2

Compare with:

_normalize_callback_options(options)

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.

Parameters

options req
