I was wondering if anyone could see the error in this littte application

I have two models, User and Selection

Selection is an extension of the User model

so in the User model I have a has\_one :selection  
and in Selection I have a belongs\_to :user

in my views, i cannot get @user.selection to work but @user works fine.

What you describe should be fine, so the problem must be somewhere else.  
Do  
you have your selection table setup with a user\_id field?

yes, the selections table has a user\_id field

One more thing to check is to make sure that the user actually has a  
selection assigned to it. Do this in the controller-

@user.selection = Selection.new

is that necessary?

I was under the assumption that the model relationships would handle  
the collection?
