Hi,

I have this form …

\<% for i in 1 … 5 %\>

| \<%= text\_field("ec\_line\_item", "prescription\_number", "index" =\> i) %\> | \<%= text\_field("ec\_line\_item", "description", "index" =\> i) %\> |
| Prescription Number | Description |

 \<% end %\>

Now on my controller end I would like to save the objects (each object  
is of class “ec\_line\_item” with attributes “prescription\_number” and  
“description”) but only if the prescription\_number attribute is not  
empty. What’s the most efficient way of doing this?

Thanks, - Dave

First, this is really a question for the rails group.  
[http://groups.google.com/group/rubyonrails-talk/topics](http://groups.google.com/group/rubyonrails-talk/topics)

That said, you should check out Ryan B. series of 3 RailsCasts
