Hi.

How do I create multiple rows in one model in a form? I have done the  
tutorial, multiple models in one form by ryan. This might be easy for  
most programmers. But I just don’t understand how to multiple rows in  
one model in a form.

Can someone please help me?

Thanks

You need to use the :index option when creating your fields (eg. with  
text\_field).

Stephen Chu has written a great post on this:

Hope that helps
