Question

I have an Event model with field status, which is string so it appears as a text_field. But I have a list of possible statuses and I want to display it as a select box. Also, when I select cancel status for a event it should ask me for the cancellation reason. I am not able to find good tutorial for this.

Answer 1

ActiveAdmin uses Formtastic for form generation, so Formtastic’s documentation should answer your questions.

You can get a select instead of a textfield with the following code:

form do |f|
  f.status, :as => :select, :collection => STATUSES #whatever collection you want to display
end

Triggering an event when selecting “cancelled” should be solved with javascript.
