ok this is really basic rails question, but how do I keep an object  
alive between controller action? I thought I could create an object and  
it would remain alive, but I am guessing the controller object gets  
recreated each time?

Rajinder, you can store the object in a session. For example, you can  
do  
the following:

Store:

session[:object\_to\_persist] = an\_object

Retrieve:

some\_local\_variable = session[:object\_to\_persist]

For further information, I would recommend reading the relevant section  
from  
“Agile Web D. with Rails 3rd” by Dave T. et al.

Good look,

-Conrad

thanks I was not sure session object was the right way to do things.  
I’ve got 3 books on Rails and I’m hoping to get “Agile Web D.  
with Rails 3rd” soon =) but I’ll will check out the section now.

Rajinder, you can read the section on “Cart Creation”. Also, there’s  
later  
section(s) in the book that goes into greater detail.

Good luck,
