activeadmin-mongoid：如何根据ID进行过滤？

Question

This doesn't work:

filter :name, :as => :string

Because mongoid ids are not strings, you can't filter on the ids as a string. Is there a nice way to filter on the ids by creating a custom filter type?

Answer 1

Found a way - I'm not sure exactly why it works yet, but:

filter :device_id, :as => :numeric

does the trick.
