I am teaching myself rails (coming from PHP for web apps) and I can't find any good docs to help me. But I was wondering how would you tell your method to take the last post(controller is post) in the database? I tried Post.find(:last) but that did nothing sadly. Anyone know? ...

I assume this is really easy, and I'm missing something obvious. I'm connecting to a legacy database that has column dblOrderQty. I'm validating it thusly: validates_numericality_of :dblOrderQty, :greater_than => 0 This, of course, presents "Dblorderqty must be greater than 0". I'd much rather have that say "Quantity must be greate...

Most of the Rails books I have touch on script.aculo.us and prototype, but because the Rails framework is so large, they don't spend a lot of time going in depth on the two packages. I really like Agile Web Development with Rails (3rd Ed.), so I was leaning towards picking up another book from Pragmatic Bookshelf specifically on script....
Xcode's syntax colouring is poor at best and textmate's looks great, but I like Xcode, since I program in C++, too. I'd like to keep everything in one place and take advantage of other Xcode features. Has anyone already done this or is there an easy way to do it? ...
I have a datetime column in a model and I want to display the form for this as separate text_fields for the time instead of the datetime_select helper drop down menus. I know I will somehow have to validate and recreate the date to go back to the DB, but I am not sure how. Should I use virtual attributes getter and setter methods? EG.....
