Rails - Feb 2006 - Error handling

Hi,
 
I''m stuck right now with a problem concerning error handling.
I''ll try to
explain the problem in short:
 
In a controller class I have a method edit:
 
def edit
    @some_class = SomeClass.find(params[:id])
end
 
The record originates from a database table. What happens if the user enters
a field that fails validation and I return to my edit page? I get the idea
that th original value from the database gets reloaded all the time, but I
want to see the value the user entered.
 
I try to create my own list of validation errors by looping through the
errors-object of the model, but I get the impression this one''s also
reset
by the find-statement of my mini-example.
 
Hopefully somebody understands what I mean and can help me out.
 
Thanks in advance,
Walter

def edit
   @some_class = SomeClass.find( params[:id] )
   if request.post? && @some_class.update_attributes(
params[:some_class] )
     redirect_to :action => ''edit_successful''
   end
end
