Hi Steve,

I got it, just had to do this sensible thing in my method: :order => “accepted_at desc”, :limit => “3”) + @user.friends_by_me.find(:all, :order => “accepted_at desc”, :limit => “3”)

@friends = @user.friends_for_me.find(:all,

and vola, it works amazingly…Thanks for this amazing plugin…

Cheers

Hi Steve,

thanks for the reply and apologies for the delayed reply, well here’s the full error:

ArgumentError in User profilesController#home

wrong number of arguments (2 for 1)

RAILS_ROOT: ./script/../config/.. Application Trace | Framework Trace | Full Trace

{RAILS_ROOT}/app/controllers/user_profiles_controller.rb:51:in `find’

{RAILS_ROOT}/app/controllers/user_profiles_controller.rb:51:in `home’

where line number 51 is: @friends = @user.friends.find(:all, :order => “accepted_at desc”, :limit => “2”)

in my view am getting the users name, and picture to be displayed, it works pretty well as long as its just @friends = @user.friends

here’s my method in controller:

def home @user = User.find(session[:user_id]) @users = User.available_users @user_pic = UserPic.find(:first, :conditions => [‘user_id=?’, current_user]) @friend = current_user @friends = @user.friends.find(:all, :order => “accepted_at desc”, :limit => “2”)

end

Just not able to get this right…Thanks a lot in advance for your help…

Cheers

@lukey: I’d love to offer some advise but I’d need you to post some more information about the error your receiving. Where are you getting the wrong argument error? Maybe posting a small portion of the error your getting? What method does the error happen on?

Hi Steve,

I am using this wonderful plug-in for my development and I have one small query problem that gives me an error, nothing wrong with the plugin but its a custom. requirement:

I need to list user names and pictures of corresponding users and that too by limiting the list to just 5 users.

Heres the controller code:

def mini_friendlist

@friend = User.find(session[:user_id]) @user = User.find(params[:id]) @friends = @user.friends.find(:all, :limit => “5”)

end

Here’s my view code:

<%=image_path url_for( :controller => “user_pics”, :action => “show_thumb”, :id => friendship.user_pic ) %>” />

<%= friendship.name %>

When I write this query I get a wrong argument error.

Please guide me with this task… any help is appreciated.

Cheers

Lukey

I wrote up a howto (kinda) so those of you who are having trouble using this plugin can check it out and see if it helps you out any. Enjoy!

Hi… I have done something almost identical although not as a plugin. The main differences is I needed the referenced class to be something other than User so any class can have_many_friends so to speak.

I also wrote this for the friends function, rather than concatenating two lists, seemed more efficient somehow…

has_many :friends, :class_name => "Person", :finder_sql =>
  'SELECT p.* FROM people p, friends f WHERE f.status = 1 AND ( (f.invitee_id = #{id} AND p.id = f.inviter_id) OR (f.inviter_id = #{id} AND p.id = f.invitee_id) )'

Ignore the minor naming differences.

I would also use a sql finder to see if someone is a friend or not rather than loading all my friends into a list and seeing if they are in the list. I believe that maybe more scaleable if someone has a huge number of friends. Also I have the friend_id’s fks indexed which also will help with performance.

Other than minor naming differences it is eerie how similar our two approaches are.

I can tell that some people are having problems with this so I’ll go ahead and make a new post that will teach the basics and maybe give some examples about how I implemented it into my restful apps in the very near future. Thanks for the comments, everyone!

Actually, have written a very dirty add_friend method in my user_controller

def add_friend #dirty code, just to get it working @friend = Friendship.new @friend.user_id = session:user @friend.friend_id = params[:id] @friend.save end

Then in the view

<% @user.pending_friends.each do |u| %> <%= u.login %> <% end %>

I’d second lambo4jos ’s comment, I’ve been messing around for ages and can’t get to first base with the controller code

This seems like a great plugin. Do you have any sample controller methods? Is it possible for you to help me out with this? I am having a difficult time figuring out the controller parts of rails and this plugin. Any help would be wonderful. Thanks in advance.

Can you give me some pointers on the best way to make this restful again? I was interested in using your restful friends idea, but that seems to not survived the transition to plugin.

@joe: hm. i never thought about this. The easiest (and somewhat non-normalized) way of doing things would be to just add a ‘friendship_type’ column to the friendship model that could hold the type of friend. The cool thing about using a relationship model is that you can add attributes to the friendship. You could also do a whole new model for friendship_type and add a ‘has_one friendship_type’ to the friendship model too. Let me know if any of those methods work for ya.

Hi Steve, I really like your plugin it’s EXACTLY what I was looking for, Thanks. I have one question though….Let’s say I wanted two types of Friends (BestFriend and RegularFriend) associated with the same Friend Class, how could I do this? I was thinking maybe making a has_one association with a child class called BestFriend and Regularfriend and adding your has_many_friends at that level, but I’m not sure if that would work. Please advise if you could, Thanks again. Joe

Sorry about that. I decided I didn’t really need the Trac’s for the time being. Everything should just link to svn.dnite.org, so I changed the links. They should work now.

Thanks for your plugin but the Trac is down now. dev.dnite.org is the same as dnite.org.
