I’m trying to call a Model class within a lib/ module with no success.  
Here’s what I’m working with:  
======================= lib/foo\_module.rb ======================  
require “pp”  
module Foo\_Module

def Foo\_Module.import\_database  
barmodel = BarModel.find\_all()

end

module ForeignTables  
#Unimportant stuff in here  
end

end  
======================end lib/foo\_module.rb ====================

When I try to run “Foo\_Module.import\_database” in the console, I get  
this error:  
NameError: uninitialized constant BarModel

BarModel was constructed with the model generator. Any ideas? I feel  
like I’m just not referencing BarModel correctly. Should it  
Models::BarModel or something?
