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 -- Posted via http://www.ruby-forum.com/.

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 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? -- Sau Sheong http://www.saush.com http://read.saush.com http://jaccal.sourceforge.net -------------- next part

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

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.

Imagine for example: table departments with columns: id, department_name table employees with columns: id, department_id, employee_name and of course the employees table has a constraint foreign key (department_id) references departments(id) So this is

Web services and security
Hi all, How do folks generally secure their Rails web services? A password in a config file? A ''webservice'' user in a ''Users'' table with its own password? LDAP authentication for every method? Only authenticate on the "important" methods? Something else I''m not thinking of? I''d like to be secure, yet practical, for the sake
