使用Rails 3.1应用程序更改活动管理员的下拉关联过滤器中显示的属性 [英] Changing what attribute is displayed in drop down association filter in active admin with Rails 3.1 app

问题描述

我在Rails应用程序中使用Active Admin gem，并且在我的一个模型管理页面上，有一个过滤器用于与另一个模型的关联。下拉菜单显示＃< Model：AxAAAAAA> 而不是适当的属性。

I am using the Active Admin gem in my Rails app, and on one of my models admin page, there is a filter for an association to another model. The drop down menu is displaying #<Model:AxAAAAAA> as opposed to the appropriate attribute.

例如，如果我的模型是帖子管理索引页面上属于用户的帖子，则将为用户提供一个过滤器，并且在该过滤器的下拉菜单中为id，例如＃<用户：abcd12345> 。我希望能够在此过滤器的下拉菜单中显示适当的内容。

For instance, if my model were posts, which belonged to users, on the posts admin index page, there would be a filter for users, and in the drop down menu for that filter would be id's such as #<User:abcd12345>. I would like to be able to display something appropriate in the drop down menu for this filter. How can I do this with Active Admin?

UPDATE

正如ciastek的回答所指出的那样，该如何使用Active Admin做到这一点？与此问题和事实上，我也使用 company_name作为属性，而不是 name

As pointed out in the answer by ciastek, this is very similar to this question and in fact, I am also using "company_name" as an attribute instead of "name"

推荐答案

我能够通过以下方式解决问题传递：label_method => ：company_name 到 admin目录下resources.rb文件中的资源。

I was able to solve my problem by passing :label_method => :company_name to the resource in the resources.rb file under the 'admin' directory.
