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 primitive form (:per_key) used by ActiveSupport::Callbacks. The basic idea is that :only => :index gets converted to :if => proc {|c| c.action_name == “index” }, but that the proc is only evaluated once per action for the lifetime of a Rails process.

Options

only - The callback should be run only for this action
<tt>except<tt> - The callback should be run for all actions except this action

Parameters

options req
