"Please use symbols for polymorphic route arguments" after updating from Rails 6.0.3.6 => 6.0.3.7

[ndbroadbent]

I have written some integration tests for my app that test some ActiveAdmin pages, and these integration tests have started crashing with this error:

     ActionView::Template::Error:
       Please use symbols for polymorphic route arguments.

This is being triggered by a call to id_column inside an index block for a resource page.

I just wanted to post this issue in case other people come across this, but I will continue investigating and try to add more information.

Should probably move the discussion to this issue on the Rails issue tracker: rails/rails#42157

Looks like it's an intentional change to fix a security vulnerability, in this commit: rails/rails@c4c21a9

ActiveAdmin might need to be updated to call to_sym in a few places

I think the issue is in inherited_resources, and a fix is mentioned here: activeadmin/inherited_resources#665

Same thing for adminsitrate, but it appears to be fixed already thoughtbot/administrate#1972

This should've been fixed by the latest inherited_resources release: https://github.com/activeadmin/inherited_resources/releases/tag/v1.13.0.

Updating inherited_resources to v1.13.0 worked
