I understand not wanting to write a try/catch block, because they are only meant to be for exceptional cases (since there is a lot of overhead associated with them). However, using try/catch is appropriate in this situation, because from what I understand, it is exceptional for a sample to not have any stages. You'll want to make sure that your data is in a runnable state, but as for the view I think that try/catch is your best bet. -- You received this message because you are subscribed to the Google Groups "Django users" group.
