Ransack no longer works with Secondbase gem.

[lcpriest]

I opened an issue on Secondbase here: customink/secondbase#56.

It looks like moving from @engine.connection.schema_cache to ::ActiveRecord::Base.connection.schema_cache will exclude tables provided in a secondary schema.

I was using Ransack with ActiveAdmin and Secondbase (to have an admin interface for my Rails app in another app, but share some parts of a database).
Ruby 2.5.0
Rails 5.1.4
Ransack 1.8.7

I understand if this is may not be an urgent/relevant issue.
The commit that added the change is
d445755.
I would love to understand what changes in Rails 5.2 it is adapting to, so that I can try submit another solution that will allow gems such as Secondbase to continue to work with Ransack.

If I have missed anything, please let me know and I am happy to add it.

Hi @varyonic, regarding this issue. Is there any reason we can't use @engine instead of ::ActiveRecord::Base. It looks like we are already using @engine in the same class.

Let me know, and I'll look after the changes.

I was building on the contribution by @bbonislawski, my guess is the change was not intentional.

I tried changing it back to @engine and the tests failed. It's going to need someone more motivated than me to fix this use case.
