Django序列化程序未将数据保存到数据库，但响应正常

from myapp.models import MyModel

data = {'field1': 'value1', 'field2': 'value2'}
instance = MyModel(**data)
instance.save()

from myapp.models import MyModel

data = {'field1': 'value1', 'field2': 'value2'}
try:
    instance = MyModel(**data)
    instance.save()
except Exception as e:
    # 处理保存失败的情况
    print(f"保存失败：{str(e)}")

from django.db import transaction
from myapp.models import MyModel

data = {'field1': 'value1', 'field2': 'value2'}
try:
    with transaction.atomic():
        instance = MyModel(**data)
        instance.save()
        transaction.commit()
except Exception as e:
    # 处理保存失败的情况
    print(f"保存失败：{str(e)}")
    transaction.rollback()
