[Rails] This modules thing somehow really does not work for me, please help.

Hey,

thank you in advance for reading this post. I struggle with
modularization / packaging / name spacing (however you want to call
it) via ruby modules. I have the feeling that somehow rails is
responsible for the problems I am facing. I hope, you can help me.

Here's an example to demonstrate more exactly what I mean:

module Storage
module Administration

def self.do_something()
# .. omitted
end

end
end

This does sometimes work under the rails console (development mode),
most of the time I get:

ruby-1.9.2-p290 :004 > Storage::Administration.do_something()
NoMethodError: undefined method `do_something' for
Storage::Administration:Module

This one here works more often (but not always):

module Storage::Administration

def self.do_something()
# .. omitted
end

end

What's about the constant resolution operator (::)? As far as I know
it is only allowed to reference constants (like module or class
names), but not directly in definitions (module X::Y::Z).

As I know it from pure ruby the first example should do it. You just
nest the modules as you need and simply reopen a module if you want to
extend it.

So, the contents of my ruby files used for this example:

"storage.rb" file (in a directory called "storage"):

module Storage
end

And my "administration.rb" (in a subdirectory of "storage" called
"administration"):

module Storage
module Administration

# .. omitted

end
end

OR (as I also tried)

module Storage::Administration

# .. omitted

end

What am I doing wrong? Why can't rails (console, runner, etc.) access
my static method _all the time_?

Thank you very much for any suggestions!
