Howdy,

I had an application perfect for ActiveResource, which I do realize is  
not  
finished.

Anyway, I froze my app to edge and then defined a class:

class Address \< ActiveResource::Base  
self.site =  
“[http://ws.geonames.org/findNearestAddress?lat=:lat&lng=:long](http://ws.geonames.org/findNearestAddress?lat=:lat&lng=:long)”  
End

I tried to use it from the console but I get the trace below.

It appears it can’t ‘see’ ActiveResource.

What am I doing wrong?

Thanks,  
Hunter

active resource isn’t a part of rails right now, so you’ll have to  
specifically require it in environment.rb.

Thanks.

I tried that by doing this:

config.load\_paths += %W( #{RAILS\_ROOT}/vendor/rails/activeresource/lib )

I am still getting the same error after restarting the server.

Is there another way to require it? I got this method from Gooooogle.
