I would like to reference constants and classes defined in module  
People in the class Schedule.

class Login is not part of any module (other than the root).

doing this:  
class Schedule  
include People  
def a\_method  
# Worker.new won’t work  
People::Worker.new # works  
end  
end

doesn’t work.

Is there a way to include the module People so that I don’t need to  
prefix People:: for only one particular class?

Also, why doesn’t what I tried work? Doesn’t include copy in the  
constants, and aren’t classes just constants?

I don’t know why it doesn’t work for you – it works fine for me.

`
module People
    class Worker
    end
end
class Schedule
include People
def a_method
p Worker.new
end
end
Schedule.new.a_method
` #

Here’s an example that works fine for me:  
module People  
POPULATION = 1234567  
end

class Schedule  
include People  
def x  
p POPULATION  
end  
end

s = Schedule.new  
s.x  
#=\> 1234567

p VERSION  
#=\> “1.8.5”

Does that make any sense? The autoloader can find them if I include  
People in the global namespace, but not if I include it in the class?!  
If so, is there a workaround?

Is it possible that Rails changes things somehow?  
I think I know - the autoloader can’t find them then!

Yes it makes sense and you are probably right. The workaround is to  
explicitly require the file

e.g:  
require ‘people’ # Or whatever the file is
