Instance Method Details

#allow_if(&block) ⇒ Object

The simplies policy. Takes block and executes it returning boolean result. Multiple policies are reduced with ||

class Action < Granite::Action
  allow_if { performer.is_a?(Recruiter) }
  allow_if { performer.is_a?(AdvancedRecruiter) }
end

The first argument in block is a current action performer, so it is possible to use a short-cut performer methods:

class Action < Granite::Action
  allow_if(&:staff?)
end
