Use just-time-picker on filter field

[Jumboweb]

Hi, thanks for this cool gem,

we have an issue when using just-time-picker input type with activeadmin filters, actually we are filtering on a has_many :through table attributes.

We have a Shop on one side, some Days on the other side, and in the OpeningTimespans association we are saving the opening frame in two time inputs (lets say 10:00 AM to 09:PM).

I want to filter on these start and end times. So I added a

filter :opening_timespans_start_at, :as => :just_time_picker

in my ActiveAdmin Shop file, and bang :

undefined method `opening_timespans_start_at_hour' for #MetaSearch::Searches::Shop:0x00000005994df0

Do you think it is more a Activeadmin, Formtastic or just-time-picker issue ?

Thanks for watching.

Rgds, Alex
