Method deprecated or moved

This method is deprecated or moved on the latest stable version. The last existing version (v5.0.0.1) is shown here.

These similar methods exist in v7.1.3.2:

ActiveSupport::Callbacks::Callback::ClassMethods#skip_callback

skip_callback(name, *filter_list, &block) public

Skip a previously set callback. Like set_callback, :if or :unless options may be passed in order to control when the callback is skipped.

class Writer < Person
   skip_callback :validate, :before, :check_membership, if: -> { self.age > 18 }
end

An ArgumentError will be raised if the callback has not already been set (unless the :raise option is set to false).
