Navigation techniques, everyone?
I''m rewriting the code to my first app. I want to reuse a lot of it, but tidy it up a lot. The first thing I will tackle is my nav-bar. Throughout a user''s experience on my app, I want it to reload as little as possible (I''ll have about 7 or 8 controllers with about 70 actions).

How to upload all images in a folder?
Instead of making a form to upload one picture at a time, I''d like to have the File Column plugin accept a directory, and have each picture be uploaded and thumbnails created (w/ RMagick). Has anyone done this? Anyone have a good idea where to start if I were to do it on my own? Thanks, Ben Lisbakken -- Posted via http://www.ruby-forum.com/.

Call action & display nothing?
Can you do a periodically_call_remote to an action but then not display any new view? say the new action was called ADD.

FK constraints overrated?
Hello folks, I use to think that a relational databases without foreign keys constraints enforced strictly by the RDBMS were no good, piece of crap, data junk. However, I''ve also learned the hard way that FKs constraints imposes serious difficulties when moving data around, specially between different DBs, or for loading test data or for upgrading DBs schemas, or for porting DBs
