Hi to all,

I just started with REST development, I created a very simple  
scaffold\_resource and a client app to test it.

All verbs works well but not list !!!

Here what I give when call Airport.find(:all)

./activeresource/lib/active\_resource/base.rb:465:in  
`instantiate_collection': undefined method `collect!’ for  
#Hash:0xb7b90ac0 (NoMethodError)  
from ./activeresource/lib/active\_resource/base.rb:442:in  
`find_every' from ./activeresource/lib/active_resource/base.rb:385:in `find’  
from client.rb:10:in `show\_airports’  
from client.rb:16

Here what I’ve generated with scaffold\_resource under Rails 1.2.5:

ruby script/generate scaffold\_resource airport name:string  
rake db:migrate

And here my (very simple) client.rb source using activeresource from  
trunk:

require ‘activesupport/lib/active\_support’  
require ‘activeresource/lib/active\_resource’

class Airport \< ActiveResource::Base  
self.site = ‘[http://localhost:3000/](http://localhost:3000/)’  
end

def show\_airports  
airports = Airport.find(:all)  
puts “I retrieved #{airports.size} airports !”  
end

new\_airport = Airport.new(:name =\> “New airport”)  
new\_airport.save  
show\_airports

Someone can help me ?

My goal is to write a system with some decoupled rails app using RESTful  
web services, is it possible at this time or may I wait for Rails 2.0 ?

Thanks in advance…
