Coding challenge broken: Finding and Building Models 2&3/3

I'm in the Building the Friendship UI badge of Building Social Features in Ruby on Rails. Yesterday I couldn't get past the third challenge, and today it's stuck on the second. Could someone at Treehouse please fix it? I've finished the course and am just stuck on this.

Thank you!

class UserFriendshipsController < ApplicationController
  def new
    if !params[:friend_id] #passes on first challenge
      @friend = User.find(params[:friend_id] #same as on video
      flash[:error] = "Boo" # Write your code here
    end
  end
end

Isn't passing for 2/2.

This question seems to be related to Ruby and not about Development Tools, right? I suggest you change the Tag to Ruby and also link the challenge, that way people that know Ruby on Rails might be able help. It's hard to help without knowing what the question is.

First of all let me note you forgot a parenthesis at the end of the find statement. Secondly you want to flash an error if there is no friend id parameter BUT if there is a friend with the id parameter you want to find it, therefore you need an else statement as the if checks if there is not a friend with the id parameter. So you have to find the friend in the else statement, after doing that you should end up with a functional code that looks like this:

class UserFriendshipsController < ApplicationController

  def new
    if !params[:friend_id] #passes on first challenge
      flash[:error] = "Boo" # Write your code here
    else
         @friend = User.find(params[:friend_id]) #same as on video
    end
  end
end

For some reason, I needed your to provide clarity so I could get through this! Once that was sorted, I passed the next one as well. Many thanks! :)
