django DRF This field may not be null

target

You need to change the original mandatory field to non mandatory

realization

First, update the fields in models, and add null = true, default = none, blank = true

1 2	name = CharField(max_length=64, verbose_name='name', null=True, default=None, blank=True) account = CharField(max_length=64, verbose_name='account', null=True, default=None, blank=True)

serializers update

1 2	name = CharField(required=False) account = CharField(required=False)

execute python manage.py makemigrations
execute python manage.py migrate

Error:

May appear this error:

1	This field may not be null.

1	This field cannot be blank.

Solution:

You need to change serializers to this

1 2	name = CharField(required=False, allow_blank=True, allow_null=True) account = CharField(required=False, allow_blank=True, allow_null=True)

allow_blank=True to solve This field cannot be blank.
allow_null=True to solve This field may not be null.
