When I tried model inheritance in new-forms admin, I faced some
problems
The below is the code i tried
class Reporter(models.Model):
first_name = models.CharField(max_length=30)
last_name = models.CharField(max_length=30)
email = models.EmailField()
def __str__(self):
return u"%s %s" % (self.first_name, self.last_name)
class ReporterChild(Reporter):
location = models.CharField(max_length=100)
def __str__(self):
return "%s" % self.location
ReporterChild._meta.get_field('reporter_ptr').blank = True
Here I can't saved the data and it throws the Value Error exception
with "Cannot assign None: "ReporterChild.reporter_ptr" does not allow
null values." error message
So I set this field to Null by adding
ReporterChild._meta.get_field('reporter_ptr').null = True
So its adds fine and working. But when I tried to delete a data. It is
throws IntegrityError exception with "datatype mismatch" message.
It can delete only commenting the added code.
What is wrong with me?
