Using with_scope with more than one model

Chinmay_K · July 11, 2007, 7:50pm

I’ve seen a lot of usage of with_scope since my last post, and
everywhere I
see code like this:

Mail.with_scope(:find=>{:conditions=>“user_id = …”}) do
count = Mail.count
end

Here, both the model used for scoping, and the model inside the scope is
the
same.

I’m trying to do something like this:

class User<ActiveRecord::Base
def among_friends
User.with_scope(:find => {:conditions => friends_scope_condition})
{yield}
end
end

so that I can do stuff like:
#Find friends’ quotes
current_user.among_friends do
@quotes_by_friends = Quote.find(:all, :order=>‘created_at DESC’)
end

Unfortunately, this doesn’t work, and to correct the code, I need to use
Quote.with_scope in the among_friends definition instead.

This defeats the purpose; which was to increase flexibility.

Would appreciate any ideas.
