ruby-on-rails – 如何在Rails 3中取消关联记录

我在使用范围在rails中正常工作时遇到了一些麻烦.

我的模特：

class User < ActiveRecord::Base
  default_scope :conditions => 'users.deleted_at IS NULL'


class Feed < ActiveRecord::Base
  belongs_to :user,:foreign_key => :author_id

当我打电话给以下人时：

feeds = Feed.includes(:user)

我想为用户跳过default_scope.所以我试过了：

feeds = Feed.unscoped.includes(:user)

但这并不是要从用户那里删除范围.有关如何使其工作的任何建议？谢谢

User.unscoped do
  @feeds = Feed.includes(:user).all
end

User.unscoped do
  @feeds = Feed.includes(:user)
end
@feeds #included Users will have default scope
