hi,
i have a model like this:
class Incident(models.Model):
escalate = models.IntegerField()
escalatelist =
models.ManyToManyField(Escalatelist,null=True,blank=True)
other fields removed for clarity. If I save this in admin, I get this
error:
'Incident' instance needs to have a primary key value before a
many-to-many relationship can be used.
the full traceback is:
