Determining if users are facebook friends (Parsing) -

i'd find out if current user friends root node user, using koala, , if so, print statement saying: friends. problem parsing of data returned facebook.

user.rb

def facebook   @facebook ||= koala::facebook::api.new(oauth_token)   block_given? ? yield(@facebook) : @facebook rescue koala::facebook::apierror => e   logger.info e.to_s   nil # or consider custom null object end  def facebook_friend   facebook.get_connection("me", "friends/#user.user_id") end 

profile.html.erb

<% if current_user.facebook_friend.include?(@user.uid)? %>   <p> friends</p>                <% else %>   <p> not friends</p>    <% end %> 

output:

<%= current_user.facebook_friend %> 

will return: [{"name"=>"elizabeth", "id"=>"100008217009369"}]

<%= @user.uid %> 

will return: 100008217009369

thanks!!!

it easier thought: in user model simple used koala method:

def facebook_friend(user)   facebook.get_connection("me", "friends/#{user.uid}") end  def my_friends_list   facebook.get_connection("me", "friends") end 

then in profile view, adding current_user , @user arguments:

<% if @user.uid.present? %>   <% if signed_in? && current_user == @user %>     <p><%= current_user.my_friends_list.count %> friends</p>   <% elsif current_user.facebook_friend(@user).empty? %>     <p><%= current_user.mutual_friends.count %> friends in common</p>   <% else %>     <p>you facebook friends</p>   <% end %> <% else %>   <p>not connected</p> <% end %>
