Rspec: wrong number of arguments (1 for 0)

This is a piece of code which throws an error "Wrong number of args (1 for 0) on the 5-th line:

describe 'PATCH #update' do
  context 'title is empty' do
    it 'should not update page' do
      page = create(:page)
      patch :update, { id: page.id, page: FactoryGirl.attributes_for(:page, title: nil) }, format: :json
      expect(response).to have_http_status(:unprocessable_entity)
    end
  end
end

Rails controller:

def update
    if @page.update(page_params)
      render json: @page
    else
      status :unprocessable_entity
    end
  end

Other tests work just fine, but this for #update's else - doesn't . Cant' get it, what's the problem and how can I fix this? (feature works just fine, but test fails)

You need to change your update method to below

def update
 if @page.update(page_params)
   render json: @page
 else
   render json: @page.errors, status: :unprocessable_entity
 end
end
