Testing scoped mass assignment with RSpec

I have a model with the following mass assignment protection defined as:

attr_accessible :attachment, :body, :feed_id
attr_accessible :attachment, :body, :feed_id, :approved, :as => :admin

The code works as expected in the controller, only allowing approved to be mass assigned when called like

@post.update_attributes(params[:post], :as => :admin)

I usually test mass assignment using shoulda like so:

it { should_not allow_mass_assignment_of(:approved) }

However, I cannot find a way to test scoped mass assignment, e.g. something like

it { should allow_mass_assignment_of(:approved, :as => :admin) }

(That doesn't work).

Does anyone know how to test this?

Solution

  • For Rails > 3.1 try 

    it { should allow_mass_assignment_of(:approved).as(:admin) }
