Help with tutorial --- Sproutcore + Rails


#1

Hi,

I have been using rails to talk to sproutcore. I did exactly what the
tutorial talks about. Also I downloaded the sproutcore-examples as
instructed in the tutorial. Now when I run the local host :
http://localhost:4020/contacts I do not get records listed on the left
pane, instead I get a message on the console as below:

REQUEST: get /sc/contacts/list
GET http://localhost:4020/sc/contacts/list?order=id

I understand the get request is posted at
http://localhost:4020/sc/contacts/list?order=id
When I looked the above URL, below is the message I get. Could someone
please help me to see where I could be going wrong ??? I have also
posted this a few days ago.

NameError in ContactsController#list

uninitialized constant ContactsController::Contact
