I am having 2 model of similar schema and I want to bulk copy from model1
to model2 but model2 is having 3 more fields but I want to store null in
these fields.
class SubscriberBalanceProcess(models.Model):
VOICE_SOC = models.CharField(max_length=50, null=True)
SMS_SOC = models.CharField(max_length=50, null=True)
DATA_SOC = models.CharField(max_length=50, null=True)
DATE_TIME = models.DateTimeField(auto_now_add=True, blank=True)
TOTAL_REMAIN_VOICE = models.BigIntegerField(default=0, null=True,
blank=True)
TOTAL_REMAIN_SMS = models.BigIntegerField(default=0, null=True,
blank=True)
TOTAL_REMAIN_DATA = models.BigIntegerField(max_length=100, null=True,
blank=True)
class Meta:
db_table = "SUBSCRIBER_BALANCE_PROCESS_TEST"
class SubscriberBalance(models.Model):
VOICE_SOC = models.CharField(max_length=50, null=True)
SMS_SOC = models.CharField(max_length=50, null=True)
DATA_SOC = models.CharField(max_length=50, null=True)
DATE_TIME = models.DateTimeField(auto_now_add=True, blank=True)
FILE_ID = models.CharField(max_length=255, null=True)
class Meta:
db_table = 'subscriber_balance'
SubscriberBalanceProcess.objects.bulk_create(SubscriberBalance.objects.filter(VOICE_STATUS='N',
SMS_FLAG=1, TENANT_ID__in=loginIdList))
