Stuck creating a user friendship - help!

I'm working on the code challenge for the "Finding and Building Models" part of the "Building Social Features in Ruby on Rails / Building The Friendship UI". I got the first two parts of the challenge right, but I'm stuck on the third. This is the code I've written:

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

This code throws an error:

in `new': undefined method `user_friendships' for #<User:0x0000000164cb10 @options={:current_user=>true}> (NoMethodError)

I have to be missing something because (1) I cut and pasted the line in question directly from the zip file containing the project files, and (2) if I add a line saying "puts current_user.methods" just before the line in question, there's no hint of anything resembling user_friendships.

So, what am I missing?

Thanks,

-- Creede

Hey Creede,

Your code is correct! We're fixing that code challenge right now. Try using the following to create the user friendship:

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

Sorry for the trouble!

Whew! I'm not insane after all!! (Well, OK, I am insane, but it doesn't have anything to do with this bit of code.) Thanks for the quick reply Jason!

Seem to still be having issues with this ( at least I am). I know the code is correct but after hitting 'Check Work' the system will stay stuck on 'Running'. I've tested across one Windows box as well as a mac machine. Although both running Chrome.

After typing that, I checked on OSX Firefox (19.0.2) and was able to get it to pass.

Sorry for the issues, Yonatan. Occasionally the code challenges will time out. We're working on fixes for that.

This discussion was more than a year ago, but I'm still having issues. I've tried: @user_friendship = UserFriendship.new(friend: @friend, user: current_user) @user_friendship = UserFriendship.new(user: current_user, friend: @friend) and @user_friendship = current_user.user_friendships.new(friend: @friend)

None of which pass. Any ideas?

Thanks!

Well, that was odd. I tried resubmitting the last one, and it took it. Sorry to bother.
