Module: ActionPolicy::Policy::Aliases

Included in:

Base

Defined in:

lib/action_policy/policy/aliases.rb

Overview

Adds rules aliases support and ability to specify the default rule.

class ApplicationPolicy
include ActionPolicy::Policy::Core
include ActionPolicy::Policy::Aliases

# define which rule to use if `authorize!` called with
# unknown rule
default_rule :manage?

alias_rule :publish?, :unpublish?, to: :update?
end

Aliases are used only during authorize! call (and do not act like real aliases).

Aliases useful when combined with CachedApply (since we can cache only the target rule).
