Subject: Adding variables to a binding

I need to run an ERB template (a normal Rails view template) in a Rails 
model (and then write the result to a file). The problem is that I need 
to run it in the scope of the calling controller. So I was thinking of 
creating a binding in the controller and pass into the model and use the 
binding there. I do however need to add variables from the model scope 
into the binding. How do I do this? Thought of using eval with the 
binding but it only seems to take an input string to eval (a block would 
have been nice I think).

The reason I do this is that the model in question is a STI model and 
each sub class may need to add different variables. If you can think of 
a better way to accomplish what I want I'll be glad to hear :)

Thanks,
