How to override default_scope in ActiveAdmin in Rails

Question

In a resource registered with ActiveAdmin, I have the following default_scope defined for the model:

default_scope :order => 'activities.updated_at DESC'

This apparently prevents me from being able to change the sorting on the resource's index page by clicking on the column titles. Is there a way to keep this default scope but get Active Admin sorting to work?

Answer 1

ActiveAdmin.register Post do
  controller do
    def scoped_collection
      Post.unscoped
    end
  end
end 

Answer 2

scope('all', default: true) { |scope| scope.where(...) }

Answer 3

  scope_to do
   Class.new do
    def self.cookies
     Cookie.unscoped
    end
   end
  end

Answer 4

Try out this solution.

#/admin/user.rb
controller do
  # for index page
  def active_admin_collection
    User.unscoped { super }
  end

  # for show, edit
  def resource
    User.unscoped { super }
  end
end

Answer 5

Are you trying to scope the activities or just order them, because this call only orders them, it is not actually scoping the query in the strictest idea.

From what I know of ActiveAdmin and from what their documentation states, you should probably set it up like this.

  class Activities < ActiveRecord::Base
    default_scope lambda { where :updated_at => true }
  end
