will_paginate with named_scopes

Question

I\'m using will_paginate for pagination, which has been working well so far, except for this one thing.

If I try to paginate a scope, for instance

class

Lowgain, klew's version should work out of the box. In your version you should write:

User.scope.paginate :page => params[:page], :per_page => 10

I prefer another approach to pagination. It allows to make controller more clean and encapsulates pagination at model level, for e.g.:

class Property < ActiveRecord::Base
  named_scope :all_properties, lambda {{ :order => "name asc" }}

  def self.admin_properties(page = 1)
    self.all_properties.paginate(:page => page, :per_page => Settings.admin.per_page)
  end
end

And in a controller pretty clear code:

class Admin::PropertiesController < Admin::AdminController
  def index
    @properties = Property.admin_properties(params[:page])
  end
end

p.s: Settings.admin.per_page - this is Searchlogic settings.
