How can I translate the following SQL query into a named_scope?
select users.*, sum(total_quantity * total_price) as points_spent
from orders
join users on users.id = orders.user_id
where pay_type = 'points'
group by user_id
order by points_spent desc
Thanks!
Try This
class User < ActiveRecord::Base
named_scope :your_name,
:select=>" users.*,sum(total_quantity * total_price) as points_spent",
:joins => :orders,
:conditions => ['pay_type = ?', 'points'],
:group ="user_id ",
:order=>'points_spent desc'
end
