works, but it's nicer to use "if hasattr(obj,field): ...." > More generally, what do you think of this statement: "If there are > any cases where you don't absolutely know if a variable is defined, > you have a broken design." it's generally reasonable; but in this case it's not about an undefined variable; it's an attribute. Since the ID value is defined only by the database, it's reasonable to leave it undefined until it's defined :-) -- Javier -- You received this message because you are subscribed to the Google Groups "Django users" group.
