Hallöchen! I examine a traceback that ends with
... File "/usr/lib/python2.6/dist-packages/django/db/models/query.py", line 351, in get % (self.model._meta.object_name, num, kwargs)) TypeError: 'DoesNotExist' object is not callable The error-triggering source code in query.py says def get(self, *args, **kwargs): """ Performs the query and returns a single object matching the given keyword arguments. """ clone = self.filter(*args, **kwargs) if self.query.can_filter(): clone = clone.order_by() num = len(clone) if num == 1: return clone._result_cache[0] if not num: raise self.model.DoesNotExist("%s matching query does not exist." % self.model._meta.object_name) raise self.model.MultipleObjectsReturned("get() returned more than one %s -- it returned %s! Lookup parameters were %s" % (self.model._meta.object_name, num, kwargs)) The last line triggers the error. This is strange for two reasons: First, DoesNotExist should be callable for all models. And secondly, there is no DoesNotExist in the last line but a MultipleObjectsReturned. My source code that is responsible for the error is: try: sample = self.samples.get() # Here, the TypeError occurs except (Sample.DoesNotExist, Sample.MultipleObjectsReturned): pass "self" is a model instance. "samples" is a M2M field of "self" to the class "Sample". In my case, ther are 20 samples connected with the "self" instances, so raising a MultipleObjectsReturned would be correct. Does anybody have an idea what is going on here? How should I proceed with debugging?
