Hi, I''m trying to create a little system where users can add each other as "friends". To do this, I''m imagining one user going to the profile of another user and clicking a link that says "Add this person as a friend". When the link is clicked, I''d like the username of both of the users to be entered into a database table called "friends". I just don''t know where to start with this (except that I set up the table). The session data for the current user is aptly called "current_user", so somehow that data, plus the username of the profile being viewed needs to be added as a row in the friends table. I''m really new to this, but I know that I probably need to create a controller for friends, and set up an action like "Add". I just don''t know how to insert those two usernames into the table properly. Any resources on this topic? Thanks in advance. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thanks in advance.First off - it sounds like you are biting off a lot more than you can chew right now. I''d really recommend getting Agile Web Development With Rails book and going through the tutorial/sample so that you can get a feel for how a rails app gets going start-to-(sort of)-finish. Sort of get some stuff under your belt before you dive in on this, I mean, because though it sounds simple you are getting into things with names like "self-referential" and "many-to-many" and "association callbacks", etc. that sort of drop into the second level of complexity in RoR. In the meantime - what you want to do is a self-referential many-to-many join. You can google for this and find it explained in many places, like here: http://www.railsweenie.com/forums/2/topics/768. c. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I thought that setting up a separate database table that just dropped in a couple of values when you click a link was pretty easy, but not obvious to me. I''ve got a copy of Agile and I''ll do some more looking online.

Cayce is right you need that book.
the view code you''ll want is
<%= link_to ''Add Friend'' [ :controller =>
''friends'', :action => ''add'',
:id => @user_id ] %>
and the code for add would look something like
class FriendsController
def add
if params[:id]
connector = UserFriends.new
connector.user_id = session[:user_id].id
connector.friend_id = params[:id]
connector.save
end
end
end

Ya setting it up properly is a bit complex for new rails programmers. Here''s another really good source: http://blog.hasmanythrough.com/articles/2006/04/21/self-referential-through. Scroll down to see a "friends" example in the user comments. Basically you''ve got a user table (nodes) and are connecting users inside that table with each other through "friendships" (edges).
