Load_missing_constant: Expected to define class in module

Rails
1

Hi I’m having some weird issues with Rails 3 and classes defined in
modules.

To be more precise I’ve created several files that define classes in the
AppBase module like:
module AppBase
class BackendMenu
[content omitted]
end
end

When a page tries to use the BackendMenu class like AppBase::BackendMenu
I get an error saying “Expected backend_menu.rb to define BackendMenu
(load error)”, but if reload the page the error no longer displays and
the application works as it’s supposed to.

The same thing happens to all the other files. Basically I need to
reload the page for each class I’m using, but after they’ve all been
loaded everything works.

Have you any ideas why I get this behavior and how to fix it?

The main problem is that if I use one of the classes in the initializers
I can’t force a reload and the application won’t start.

Rails’ magic code loading would expect this file to be in app_base/
backend_menu.rb
app_base.rb should define the AppBase module (possibly empty). Have
you tried that?

Hurrah, It works. The files were in the appbase folder so that’s what
the problem was. Forgot to add the underscore.

Many thanks.
