Best place for generic utility classes?
I have some code that is simply formatting and parsing URLs and I really
don''t want to associate it with a view or a controller or a model - I
just want it to be available as a utility class.
Where should this utility class go?
I would have to import it into my controller using "require" correct?
Thanks,
Wes

How to secure web services created by ActionWebService?
Hi,
Does anyone know how I can go about securing web services created from
ActionWebService? The manual from rubyonrails.org
(http://manuals.rubyonrails.com/read/book/10) doesn''t say anything at
all on this ... or do I have to implement my own access control?

Image manipulation/resizing server-side?
I''d like to implement a system in a Rails app where I allow the user to
upload an image file, and then the app takes that image and manipulates
it, saving a thumbnail, small, and original size version of the file to
the server.
How would I go about doing that?
Thanks,
Jeff

Ruby on Rails developers in Singapore?
...in Singapore, and if so would like to
meet up to chat and talk shop? Maybe even form a support group for
Rails, or form a community of Rails developers here? I''ve been using
Rails for the past months developing an in-house web application, a port
from an older application.
Thks!

[OT] Ruby ftp client for windows
I know this is off topic, But, my boss has tasked me with finding a better
ftp client than the one in Windows XP. Is there a Ruby client that can
recover dropped connections, ( a resume feature)? Would be nice if it could
handle secure/ encrypted transmissions as well?
Failing that, can anyone recommend a good scriptable ftp client for the
Windows plaftorm?

Documenting web services API''s
Sorry to have to post this again - it was probably under the wrong
subject and went unnoticed.
Is there a standard for providing user documentation for methods that
I expose through we services?
The default documentation (method names and return types) that
appears when the user visits http://localhost:3000/backend/invoke is
concise and correct, but a bit terse. How can I give my users a little

ad-hoc query
How do you run an ad-hoc query that does not belong in any model? I
thought it was something like ActiveRecord::connection.find("my
query..."), but I can''t seem to find the documentation on it. I know
I''ve seen it somewhere before, though.

Oracle and MySql simultaneously from rails app
I searched this site on Oracle && MySql, nothing came up, so perhaps
this is a new topic for this forum.
I''d like to access two databases from the same application
simultaneously (well, more precisely, in rapid succession, calling one
first and then the other, as any "joins" will be done in the application
code).
One database is in MySql, the other is Oracle.
