Hi There:

If I raise an exception in a Non Active Record Model object on call from  
Controller that extends from ApplicationController, what are the best  
ways to show it on the view side as an error?

Thanks much.

I raise exception in Non Active Record Model.  
I then have in Controller  
begin  
@some\_var=NonActiveRecordModel.find\_by\_something  
rescue =\> e  
raise e  
end

But the exception doesn’t reach the Controller from the Non Active  
Record Model?  
Something missing here.

Seems Controller Exception Handling kicks in as usual.  
Wanted to avoid as this is part of JS AJAX request.
