A good thing to keep in mind is null is for the database, and blank is for django validation -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Field forced to not-null
Hi Philip,
The field is required because you haven't allowed it to be blank - and
django admin requires fields to have the following attributes if you don't
require them:
Active = models.CharField(max_length=1, null=True, blank=True)
Otherwise the GUI will mark the field as required.
See here: https://docs.djangoproject.com/en/2.1/ref/models/fields/#blank

Andréas

Field forced to not-null
Hallo,
I have created a model that looks like this:
class ActionType(models.Model):
"""The type of actions that must be taken at a meeting with respect to
agenda points e.g. 'Decide', 'Take Note'etc.
"""
AtpCode = models.CharField(max_length=4)
AtpDesc = models.CharField(max_length=80, null=False)
Active = models.CharField(max_length=1, null=True)
class Meta:
unique_together = (('AtpCode'),)
def __str__(self):
"""Return a string representation of the model"""
return self.AtpCode
I am using SQLite as I am developing.
When I deploy this model to SQLite, the Active field is forced to be
non-null although explicitly indicate the null=True.
Any idea why this is happening? I have deleted the complete Django project
and started from scratch only to find the same scenario; when I click save,
I get the following message.
Any advice will be welcomed.
Regards,
Phlip
