Django admin panel converts None type data to empty string

Question

Any edit made to an object in the django admin panel changes all string fields having None to empty string ie '' .

Is there a workaround or does it requires changes in the django code itself.

Django version: 1.8.5

Answer 1

My guess is that problem within field definition in model, add null=True to allow storing null values within database.

From Django Model field reference#null :

If True, Django will store empty values as NULL in the database. Default is False.
