Sql query with pagination

Rails
1

I am Using will_paginate plugin in a call like :

@homes = Home.paginate(:all, :conditions => conditions…

I want to have minimum and maximum price within all @homes searched. How
would I do that efficiently?
Since I do pagination, the @homes variable doesn’t contain all the
“homes” objects, but only partial ones for pagination. Do I have to do
another query with same conditions without pagination to get it?

use named scopes, read a bit about them, lets you chain them like this
Home.ranged(6…9).paginate( etc etc)
