我在我的rails应用程序上设置了活动管理员。我运行生成器来创建用户资源,但是当我点击管理仪表板上的用户链接时,我得到:
NoMethodError in Admin/users#index
Showing /Users/nelsonkeating/.rvm/rubies/ruby-1.9.2-p290/lib/ruby/gems/1.9.1/gems/activeadmin-0.4.4/app/views/active_admin/resource/index.html.arb where line #1 raised:
undefined method `city_id_contains' for #<MetaSearch::Searches::User:0x007fde92d69840>
Extracted source (around line #1):
1: render renderer_for(:index)
我不知道是什么产生了这个或错误来自何处..任何想法?谢谢! (如果您需要查看任何其他文件,请告诉我)

这个问题帮助我解决了我的问题。我必须阅读评论以找出如何解决它,所以我在这里提供答案:
如果您的模型包含belongs_to关系,如果您的列名与您所属的外键ID列名相匹配,Active Admin将不会喜欢它。
例如,在这种情况下,您的外键是“city_id”,但您还有一个名为“city”的列。 Active Admin不喜欢这个。同样,开始使用该列确实没有意义。因为你将通过这种关系进入城市。
要解决此问题,您应该创建一个删除城市列的迁移。
class RemoveCityFromUser < ActiveRecord::Migration
def up
remove_column :users, :city
end
end
