Django 事务管理

使用Django进行事务管理的优势和案例代码

python
from django.db import transaction
@transaction.atomic
def create_order(request):
    try:
        with transaction.atomic():
            # 开启事务
            # 执行数据库操作
            order = Order.objects.create(...)
            item1 = OrderItem.objects.create(order=order, ...)
            item2 = OrderItem.objects.create(order=order, ...)
            
            # 提交事务
            transaction.commit()
            
            # 返回成功消息
            return HttpResponse("Order created successfully.")
    except:
        # 发生异常时回滚事务
        transaction.rollback()
        
        # 返回错误消息
        return HttpResponse("Error creating order.")
