Django Admin interface with pickled set
- by Rosarch
I have a model that has a pickled set of strings. (It has to be pickled, because Django has no built in set field, right?)
class Foo(models.Model):
__bar = models.TextField(default=lambda: cPickle.dumps(set()), primary_key=True)
def get_bar(self):
return cPickle.loads(str(self.__bar))
def set_bar(self, values):
self.__bar = cPickle.dumps(values)
bar = property(get_bar, set_bar)
I would like the set to be editable in the admin interface. Obviously the user won't be working with the pickled string directly. Also, the interface would need a widget for adding/removing strings from a set.
What is the best way to go about doing this? I'm not super familiar with Django's admin system. Do I need to build a custom admin widget or something?
Update: If I do need a custom widget, this looks helpful: http://www.fictitiousnonsense.com/archives/22
