django model default="" and "This field cannot be blank"

I have a model with this field:

my_field = models.CharField(max_length=100, default='')

I have the default set to empty string but when I create an object with my_field="", it says "This field cannot be blank". Does default='' not imply that it can be blank? Do I have to explicitly set the blank=True?

Yes, you need to set blank=True.

my_field = models.CharField(max_length=100, default='', blank=True)
