Building the Friendship UI: Code Challenge 1/3

This is very aggrivating. The following code is not working:

class UserFriendshipsController < ApplicationController
  def create
   @friend = User.where(profile_name: params[:user_friendship][:friend_id]).first
   @user_friendship = UserFriendship.new(friend: @friend, user: current_user)
   if @user_friendship.save
     flash[:success] = "Friendship created."
   end
  end
end

Link to the challenge: http://teamtreehouse.com/library/building-social-features-in-ruby-on-rails-2/building-the-friendship-ui/saving-models-and-redirecting

This is pasted directly from my "follow-along" code and it's working fine with my unit tests:

def create
    if params[:user_friendship] && params[:user_friendship].has_key?(:friend_id)
      @friend = User.where(profile_name: params[:user_friendship][:friend_id]).first
      @user_friendship = current_user.user_friendships.new friend: @friend
      @user_friendship.save
      flash[:success] = "New friend, #{@friend.full_name}, added!"
      redirect_to profile_path(@friend)
    else
      flash[:error] = "Friend Required"
      redirect_to root_path
    end
  end

I was able to pass the test after finding some code in another thread. This is a terrible code challenge and needs to be reworked. There is not enough information for what's requested of a student within the first question. That's ridiculous.

if params[:friend_id]
      @friend = User.find(params[:friend_id])
      @user_friendship = current_user.user_friendships.new(friend: @friend)
      if @user_friendship.save
        flash[:success] = "Friendship created."
        redirect_to profile_path(@friend)
      else
        flash[:error] = "There was a problem."
        redirect_to profile_path(@friend)
      end
    end

Thank you Robert -- your code worked for me. I agree that this code exercise needs work and have seen other threads calling for the same.

Most frustrating to me was that my actual, working controller code was not doing the trick. I assume there are unit tests behind the code exercise validation -- it would be great to be able to view the validation code when one is having issues to ensure that the proper variables, etc., are being populated.
