没有空字符串的Django CharField

Question

Is there any way to make a CharField (or TextField) that doesn't accept empty strings? I'm trying to use blank=False but it's not working...

class Foo(models.Model):
    title = models.CharField(max_length=124, blank=False)

Then after syncdb I run python manage.py shell , and I can type:

f = Foo()
f.save()

and it doesn't complain. The object has a title with a value '' . I don't want this to happen, I want it to complain if Foo() isn't explicitly given a non-empty string. Any way to do this?

I'm using Django 1.6

Answer 1

Use a MinLengthValidator :

from django.core.validators import MinLengthValidator
...
title = models.CharField(max_length=10, validators=[MinLengthValidator(1)])

Answer 2

According to the documentation , blank=False is purely validation-related that works only on a form level.
