Rails table_name_prefix is not working as expected

Question

I'm using Rails 4. I have app/models/admin.rb and app/models/admin/retention_email.rb that has something like:

# app/models/admin.rb
module Admin
  def self.table_name_prefix
    "global_admin_"
  end
end


# app/models/admin/retention_email.rb
module Admin
  class RetentionEmail < ApplicationRecord
  end
end

Now I was expecting Admin::RetentionEmail to use global_admin_retention_emails table however seems I'm still using retention_emails:

2.4.1 (main):0 > Admin::RetentionEmail.table_name
=> "retention_emails"

Any ideas how to fix this?

Add config/initializers/namespace.rb with:

require Rails.root.join('app', 'models', 'admin')
