Change const_get to constantize to fix undefined method `default_scoped'

Created by: joshua5201

Found a strange problem when my namespace and model name are the same (e.g. Order::Order) config/routes

resources :order do
  resources :orders
end

When restart / modify source and the rails got reloaded, accessing /admin/order/orders and I get:

undefined method `default_scoped' for Order:Module

No problem if I get back to /admin and click the navigator link in the left.

And I found that in rails console

Object.const_get('Order::Order') 
=> Order
"Order::Order".constantize 
=> Order::Order

using constantize, I can get the correct model class name.

p.s. my model sources

app/models/order.rb

module Order
  def self.table_name_prefix
    'order_'
  end
end

app/models/order/order.rb

class Order::Order < ApplicationRecord
end
