AR Models in Module

Hello all,

I have a module, illustrated below, with a few classes. I have required
environment.rb and can access my models just fine outside the module,
and even within the module's root, but once I try and access one inside
a module class I get an uninitialized constant error. Anyone know how I
can access these models within these module classes?

Anyone? Please help me out with this.
