Activeadmin: ActiveAdmin Filters For UUID

Created on 4 Apr 2016 · 3Comments · Source: activeadmin/activeadmin

I have implemented UUID functionality on user model using the below link http://rny.io/rails/postgresql/2013/07/27/use-uuids-in-rails-4-with-postgresql.html

Now my current schema looks like this:

create_table "users", force: :cascade do |t|
t.string   "email",
t.string   "first_name"
t.string   "last_name"
t.uuid     "user_uid",   default: "uuid_generate_v4()"
end

I tried to use below two lines to add a filter on active admin user index page

filter :user_uid, as: :uuid, label: "USER UUID"
filter :user_uid, as: :string, label: "USER UUID"

But I am getting following error like below:

Started GET "/admin/users?utf8=%E2%9C%93&q%5Buser_uid_cont%5D=b216d8af-fbd5-401f-886e-3615b8f57cee&commit=Filter&order=id_desc" for 127.0.0.1 at 2016-04-04 23:08:03 +0530

Any suggestions for using ActiveAdmin filters with UUID
