Multiple polymorphic association search using Ransack, is it possible?

Question

I have the class Invoice that belongs_to Invoiceable, a polymorphic class. The Invoiceable of Invoice can either be Subscription or Purchase.

I need to be able to search by the status of an Invoice's Subscription or Purchase.

I'm trying the following to no success:

<%= f.check_box :invoiceable_of_Subscription_or_Purchase_type_status_in, { multiple: true }, type[1], false %>

I tried different combinations like:

<%= f.check_box :invoiceable_of_Subscription_type_or_invoiceable_of_Purchase_type_status_in, { multiple: true }, type[1], false %>

But I always get a Polymorphic associations do not support computing the class. error.

Is this possible? Ransack documentation only explains how to search by a single polymorphic associated model.

Answer 1

You were very close to the answer.

You need to specify column name with each of the polymorphic association

use below combination :

<%= f.check_box :invoiceable_of_Subscription_type_status_or_invoiceable_of_Purchase_type_status_in, { multiple: true }, type[1], false %>
