Question

#!ruby
class Car < ActiveRecord::Base
  belongs_to  :user
end

@cars = Car.where(:user_id => current_user.id).limit(10)

I want to create a scope, how can I use the association :user in the scope?

(rails3)

Answer 1

So, in your model:

scope :foo, lambda {|u| where( :user_id => u ).limit(10) }

…which you can then call from your controller with:

Car.foo(current_user)
