Create a new UserFriendship instance variable set to user_friendship with the user set to the current_user and the friend set to the @friend instance variable.

@steve, That's what I would expect to work as well, but it doesn't pass. Based on what I just learned in the tutorial, I would expect to be able to write:

@user_friendship = current_user.user_friendships.new(friend: @friend)

So, on step 3/3 for the "Finding and building models" challenge, I was expecting the final code to be:

class UserFriendshipsController < ApplicationController
  def new
    @friend = User.find(params[:friend_id])
    @user_friendship = current_user.user_friendships.new(friend: @friend)
    unless params[:friend_id]
        flash[:error] = "Friendship required"
    end
  end
end

I cannot for the life of me get beyond this challenge.

We didn't go over anything like this in the video, but it works:

@user_friendship = UserFriendship.new(:user => current_user, :friend => @friend)

Making the final code for step 3 in the challenge:

class UserFriendshipsController < ApplicationController
  def new
    @friend = User.find(params[:friend_id])
    @user_friendship = UserFriendship.new(:user => current_user, :friend => @friend)
    unless params[:friend_id]
        flash[:error] = "Friendship required"
    end
  end
end

Really threw me off.

Hi Bruce,

I'm afraid I don't know what code challenge you're on. We need a bit more detail from you to help. Would you please send an email to help@teamtreehouse.com with a screenshot of the code challenge as you're working on it, and a link to the code challenge?

Screenshots will help us see what quiz or code challenge your on, what it is asking you exactly, what your answer is, and what the error message or hint says to you when it pops up. Thank you so much! :)

What you need to do in this challenge is find out if the params[:friend_id] exists.

if param[:friend_id]

But that is what I did.

def new 
  if params[:friend_id]
    @friend = User.find(params[:freind_id])
    @user_friendship = UserFriendship.find(params[:user_id])
  else
    flash[:error] = "Friend required"
  end
end

Ok your code passes until you get to the part where you make a new friendship.

You should do something like

@user_friendship = UserFriendship.new(:user => current_user, :friend => @friend)

instead of

 @user_friendship = UserFriendship.find(params[:user_id])

That worked, but i question should i have known that syntax at this point in the tutorial?

It stumped me when I did it a few weeks ago. I just had to write out the command literally. The command is also written differently from the project files.

If you look in the project files you can see the full syntax for creating a user friendship.

Sorry for the trouble on this one, guys! Is everything working for you now, Bruce?

Yes it is working based on Jody's response. Understanding there are multiple ways to solve any problem. Would you have expected the question to be answered the way it ways?

Hey Jason, I got it work using Bruce's code above, but not if I tried the code used in the video:

@user_friendship = current_user.user_friendships.new(friend: @friend)

Same problem here. Using the code used in the video gives me:
