As stated in section C2 of the second edition of AWDR (pages 102 -- 103 of
my brand-spanking new PDF):
"So far we''ve been enjoying the fact that Rails automatically
reloads
program files before handling each new request in development mode.
However, that''s not the full story. In fact, Rails only reloads those
files
_that it knows about_ [italics in the book]. If one of our files subclasses
a standard Rails class, then Rails knows about it, and manages appropriately
... we can tell Rails to reload our models by including a single _include_
[bold in original] directive in each."
The illustration then adds the line "include Reloadable" in both the
Cart
class and the CartItem class.
"Including _Reloadable_ says ''treat the Cart and CartItem classes
as if they
were like any other Rails model, and reload them before each request.''
...
In future, we''ll remember to add the _include Reloadable_ line in
non-database models, and we won''t have to restart."
There''s your answer. :)

Subject: [Rails] Tip, may even be useful
Here''s something that caused me a couple of hours of head-scratching
today:
Apparently, if your model doesn''t derive from ActiveRecord, it is NOT
reloaded for each operation in the development environment.
I was working with something that uses a single model per session, and
stores its data in the session. I kept wondering why I didn''t see my
changes. Finally, I changed the way I was naming a temporary file, and
saw that it was distinctly NOT changed in the running application.
A light went on, I restarted the server, and things went much better
after that.
I suspect there''s an easy way to force the re-loading. Anybody know
what
it is?
