Hi, I've got a question about the find() method in RoR This is my code: actions=Action.find(:all, :conditions => "ActivityID='actid'") This should return a list, array, hash, ... ? of Actions. What type of data does find() return? And how do I run through it? I would like to show Action.ActionCode for every action in actions. I tried: for action in actions output += action.ActionCode end Didn't work. Thanks, Steven.

Um, this seems to be a question of understanding Ruby the programming language rather than understanding Rails the framework. #find returns an Array object. There are many ways to iterate through an array, you should check the Ruby documentation here: http://www.ruby-doc.org/core/ Steven De Ryck wrote: > I would like to show Action.ActionCode for every action in actions. > Steven. > > -- Sau Sheong http://blog.saush.com http://read.saush.com http://jaccal.sourceforge.net

It returns an array of hashes. Try going into the console (ruby script/console) and doing your actions=Action.find(:all...) and it'll echo the resulting array. By the way, action.ActionCode doesn't look right -- attributes are normally lower case. Hope this helps

My bad. That's what happens when a noob tries to help another noob :-( Thanks for clarifying.

No problem, just trying to be helpful. Let me guess: You (like I) came from Perl? :-) There are *no* built in types in Ruby, everything is an object. The question is, what type of object is it? I only point this out because I see a lot of new users suggesting that most output from .inspect is displaying hashes, when they're really looking at objects that are NOT hashes. I've learned a lot by helping others on the list, and occasionally being wrong and getting corrected, so keep up the good work! -- -- Tom Mornini

No, PHP. About 25% through the Pickaxe at the moment (and would recommend to all noobs that they take the time to read it -- rails starts to make much more sense). Taking a bit of time for the whole OO thing to sink in, but actually I'm lovin it.
