Treebook, not able to set @friend variable for user_friendships

    <h1>Friends</h1>
</div>

<% @user_friendship.each do |friendship| %>
    <% friend = friendship.friend %>
    <div id="<%= dom_id(friendship) %>" class="friend">
      <div class="">
        <%= link_to 'friend.full_name', user_path(friend) %>
      </div>
      <div class="">
        <strong><%= friend.full_name %></strong><br />

          <% if friendship.pending? %>
            <em>Friendship is pending.</em> <%= link_to "Delete request", edit_user_friendship_path(friendship.friend.profile_name) %>.
          <% end %>

          <% if friendship.requested? %>
            <em>Friendship requested.</em> <%= link_to "Accept friendship", edit_user_friendship_path(friendship.friend.profile_name) %>.

    </div>
<% end %>''' 

You'll see that I get an error on this line: ```  <%= link_to 'friend.full_name', user_path(friend) %>```. user_path show is where you view a users profile info as I created an users_controller with different methods to update an aboutme and gender attributes and the friend variable isn't passing the ID to be able to view the profile or get its full_name method.

Here's my code for user_friendships_controller: 
```class UserFriendshipsController < ApplicationController
    before_filter :authenticate_user!

    def new 
        if params[:friend_id]
            @friend = User.where(profile_name: params[:friend_id]).first
            raise ActiveRecord::RecordNotFound if @friend.nil?
            @user_friendship = current_user.user_friendships.new(friend: @friend)
        else
            flash[:error] = "Friend required"
        end
    rescue ActiveRecord::RecordNotFound
        render file: 'public/404', status: :not_found
    end

    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] = "Network invitation sent to @friend.first_name."
            redirect_to user_path(@friend)
        else
            flash[:error] = "Friend required"
            redirect_to root_path
        end 
    end

    def index
        @user_friendship = current_user.user_friendships.all
    end

    def accept
        @user_friendship = current_user.user_friendships.find(params[:id])
        if @user_friendship.accept!
            flash[:success] = "You are now friends with #{@user_friendship.friend.full_name}"
        else
            flash[:error] = "That friendship could not be accepted."
        end 
        redirect_to user_friendships_path
    end

    def edit
        @user_friendship = current_user.user_friendships.find(params[:id])
        @friend = @user_friendship.friend
    end
end'''

Also when I request a friend the message says "Friend @friend.full_name requested"

If you need anything else just let me know. and thanks in advance!
