Gunakan yang dapat dipanggil sebagai gantinya, mis., Gunakan `dict` alih -alih` {} `
# You have two options here:
# 1.Rely on dict as a default; this will result in your models using an empty dict {} if none is supplied:
class UnderwritingValidator(TimeStampedModel):
plan = models.PositiveIntegerField(null=True, blank=True, unique=True)
logic = JSONField(default=dict)
# 2.Create your own "callable" and use it as default:
def get_default_something():
return {'accept_list': [], 'reject_list': []}
class UnderwritingValidator(TimeStampedModel):
plan = models.PositiveIntegerField(null=True, blank=True, unique=True)
logic = JSONField(default=get_default_something)
