我正试图测试' destroy'我的嵌套注释控制器的操作。 Post has_many Comments
。我之前遇到过类似的问题并且理解我需要传递一个id,但我仍然遇到一个非常熟悉的错误...
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)>'
comments_controller_spec.rb
RSpec.describe CommentsController, :type => :controller do
before :each do
@post = FactoryGirl.create(:post)
end
....
describe '#DELETE destroy' do
it 'deletes a comment' do
delete :destroy, comment: create(:comment), post_id: @post
expect(response).to redirect_to post_path
end
end
end
comments_controller.rb
def destroy
@post = Post.find(params[:post_id])
@comment = @post.comments.find(params[:id])
@comment.destroy
redirect_to post_path(@post)
end
的routes.rb

答案 0 :(得分:4)
您要申请的路线是:
/posts/:post_id/comments/:id(.:format)
但您要发送以下参数:
{:action=>"destroy", :comment=>"1", :controller=>"comments", :post_id=>"1"}
您需要将comment.id
作为id
参数发送。
试试这个:
describe '#DELETE destroy' do
it 'deletes a comment' do
comment = create(:comment)
@post.comments << comment
# Also, test if the action really deletes a comment.
expect{delete :destroy, id: comment.id, post_id: @post}.
to change{@post.comments.count}.by(-1)
expect(response).to redirect_to post_path
end
end
