STI model with autoload_paths, rails_admin will throw Circular dependency error

[TangMonk]

I have some STI model, and place theme in modes/product

$ ls models/product
product.rb
jianpianyi_product.rb # inherit product.rb
wash_product.rb # inherit product.rb 

and add config.autoload_paths += Dir[Rails.root.join('app', 'models', '**')] to application.rb

then refresh admin page (http://localhost:3000/admin/product), will throw

Models are meant to be eager-loaded, not auto-loaded.
