activerecord - Rails 6 API Only - Namespace Models - Can not resolve the namespace models in controllers

Question

I have namespace models like so

# /app/models/metadata.rb
module Metadata
  class << self
    def table_name_prefix
      "metadata_"
    end
  end
end

# /app/models/metadata/object.rb
class Metadata::Object < ActiveRecord::Base
end

# no nested
class TestController < ActionController::API
end 

When I run in rails c it can resolve the Metadata::Object like so

Metadata::Object.find_by(key: 'XXXX')
  Metadata::Object Load (0.3ms)  SELECT `metadata_objects`.* FROM `metadata_objects` WHERE `metadata_objects`.`key` = 'XXXX' LIMIT 1

but in controllers, it can't resolve the model ::Metadata::Object.find_by(key: 'XXXX')

NameError Exception: uninitialized constant Metadata::Object
