You're assigning a queryset (basically, a list) of one Choice objects to c - hence the square brackets when you print it. As the documentation explains, `filter` *always* returns a queryset, even if only one object matches.
You can do c[0] to get the Choice object, or use `get()` instead of `filter()` (although note that will raise an exception if zero or > 1 objects match). -- DR. -- You received this message because you are subscribed to the Google Groups "Django users" group.
