Hi all,

I have a pretty simple set of models.

current\_user has a bunch of friends and each friend makes a lot of  
posts.

I want to do something like current\_user.friends.posts but the posts  
method is missing.

I’ve come up with a bunch of ways to accomplish this but nothing looks  
very good. What’s the most elegant way to do it?

Thanks,  
Alex

Create the posts method yourself by extending the association:

has\_many :friends do  
def posts  
#get posts here  
end  
end

See the Association Extensions in the api docs for a few variables that  
you might need to make that work.

Thanks so much for your reponse.

Right now I have the following code:

has\_many :friendships\_by\_me,  
:foreign\_key =\> ‘user\_id’,  
:class\_name =\> ‘Friendship’ do  
def posts  
Post.find(:all,  
:include =\> {:user, :friendships},  
:conditions =\> [‘friendships.user\_id = ?’, self.id])  
end

which should work but self.id is returning the id of the Friendship  
class. How do I get it to return the id of the user?

Thanks,  
Alex

Awesome!

What worked for me was:

has\_many :friends do  
def posts  
map(&:posts)  
end  
end

That is so much nicer looking then my first attempt.

This little one liner should do it for you, if I’m not mistaken.

current\_user.friends.map(&:posts)

which is equivalent to:

current\_user.friends.map{|f| f.posts}
