RailsAdmin with polymorphic associations

Question

I am using, Rails 4.1, RailsAdmin 0.8.1 and Mongoid 5.0.1. I defined has_many / belongs_to relationship between Products and Pictures RailsAdmin generates a Product dropdown in the Picture model. I can choose Product or I can search for Product.

I implemented polymorphic association between Products, Pictures and Employees. Now when I edit Picture I have 2 dropdowns - to choose type (Product or Employee) and 2nd to choose the actual record.

The problem is RailsAdmin is trying to load the entire Employee or Product list into 2nd dropdown. I have many thousands Employees and eventually it timesout. Any ideas how to search?

Answer 1

The dropdown lists are populated when page is loaded. The second dropdown will have everything you send during page loading (before you have chosen 'type' in first dropdown).

What I think you want can be achieved using ajax to send a request when first dropdown is selected, retrieve the values and then populate your second dropdown list.
