Hi you all,

Having into account the following:

\<%= collection\_select(“page”, “subjects” , @subjects, “id”, “name”) %\>

and that “Page” is an AR model with an attr. accesor called “subjects”,  
array composed by non AR model objects (“Subject” is a model  
representing a file), my question is:  
I can get all my @subjects from my file but, how can I set the id and  
name? Is it enough to add a “def id” and “def name” methods in my non-AR  
model in order to my view get these att. right? Becuase if I have to use  
“select” I can not provide any value at all (I mean, the id and name),  
can I?

Thanks.
