Destroying friendships (not literally, just the lesson) delete method error

Hey got a error when defining 'destroy' on the "friendships_controller" saying that the delete method isn't defined.

  1) Error:

test: #destroy when logged in should delete user friendships. (UserFriendshipsCo
ntrollerTest):
NoMethodError: undefined method `delete' for nil:NilClass

So I was wondering should I make an empty "def delete" in the friendships controller?

Also here's the argument that it's complaining about,

should "delete user friendships" do
        assert_difference 'UserFriendship.count', -2 do
    delete :destroy, id: @user_friendship
end

Oops found it, I should have had the users(:drew) actually = users(:allan). Once again it's a typing error on my part.

Looks like it's having trouble finding @user_friendship. Have you tried just giving it an id:? Maybe id: 1?

Hmm, I tried that out and got a different error saying that it couldn't find the id "1", but I thought it would be able to find @user_friendship due to the 'context'.

        context "when logged in" do
            setup do
            @friend = create(:user)
            @user_friendship = create(:accepted_user_friendship, friend: @friend, user: users(:allan))
            create(:accepted_user_friendship, friend: users(:drew), user: @friend)

            sign_in users(:allan)
    end

    should "delete user friendships" do
        assert_difference 'UserFriendship.count', -2 do
            delete :destroy, id: @user_friendship
        end
    end

    should "set the flash" do
        delete :destroy, id: @user_friendship
        assert_equal "Friendship destroyed", flash[:success]
    end
end

4th line, it shows a created '@user_friendship and what is inside.

Nice! Glad to hear you found the culprit. Debugging is turning my brain to mush. I think it's time for a day of comic books and soda pop.
