Я пытаюсь проверить действие «уничтожить» для моего контроллера вложенных комментариев.Post has_many Comments, Я сталкивался с подобными проблемами раньше и понимаю, что мне нужно передать идентификатор, но я все еще сталкиваюсь с очень знакомой ошибкой ...

Failures:

  1) CommentsController#DELETE destroy deletes a comment
     Failure/Error: delete :destroy, comment: create(:comment), post_id: @post
     ActionController::UrlGenerationError:
       No route matches {:action=>"destroy", :comment=>"1", :controller=>"comments", :post_id=>"1"}
     # ./spec/controllers/comments_controller_spec.rb:19:in `block (3 levels) in <top (required)>'

        describe '#DELETE destroy' do
          it 'deletes a comment' do
            delete :destroy, comment: create(:comment), post_id: @post
