Rails 3 - Getting NameError after accessing models via has_many

Question

Hey folks,

I have following models:

class App::Module::Object < AR::Base
  has_many :objects, :class_name => 'App::OtherModule::Object'
end

and

class App::OtherModule::Object < AR::Base
  belongs_to :object, :class_name => 'App::Module::Object'
end

Using Rails 3.0.0 and Ruby 1.9.2, I get following error after accessing App::Module::Object.first.objects:

NameError: uninitialized constant App::Module::Object::OtherModule::Object

For clearness: Rails generate the wrong class name, App::Module::Object::OtherModule::Object instead of App::OtherModule::Object. It appends the :class_name attribute to the current namespace, instead of replacing it.

Unfortunately same code is working in Rails 2.0, hope anyone out there can help me?

Answer 1

Rails 3 is not autoloading files from lib anymore. So you need add it if you want the same result in your application.rb

config.autoload_paths += %W( #{#{config.root}/lib )

or you could just require each of the files you want.

Seems to be a typo, fixed, but Rails behavior is strange. Whatever, thank you guys. :)
