我在查询中得到重复的代码,如何将2个变量合并为1行
def destroy(self, request, pk=None):
date_time = datetime.now()
user = get_object_or_404(User, pk=request.user.id)
transaction = TransactionVariant.objects.filter(transaction__pk=pk).update(deleted_at=date_time)
transaction = Transaction.objects.filter(id=pk).update(deleted_at=date_time)
serializer = TransactionSerializer(transaction, many=True)
return Response(serializer.data, many=True)
我的模特:
transaction.py
class Transaction(models.Model):
user = models.ForeignKey(
settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
address = models.TextField()
status = models.CharField(max_length=100)
total = models.BigIntegerField()
phone_number = models.CharField(max_length=10)
created_at = models.DateTimeField(auto_now_add=True, blank=True)
updated_at = models.DateTimeField(auto_now_add=True, blank=True)
deleted_at = models.DateTimeField(null=True, blank=True)
class Meta:
db_table = "transaction"
transaction_variant.py
class TransactionVariant(models.Model):
transaction = models.ForeignKey(Transaction, on_delete=models.CASCADE)
variant = models.ForeignKey(Variant, on_delete=models.CASCADE)
quantity = models.IntegerField(default=0)
created_at = models.DateTimeField(auto_now_add=True, blank=True)
updated_at = models.DateTimeField(auto_now_add=True, blank=True)
deleted_at = models.DateTimeField(null=True, blank=True)
class Meta:
db_table = "transaction_variant"
