Django 框架：'UserView' 对象没有属性 'object'
Django Framework: 'UserView' object has no attribute 'object'
我是第一次使用 Django Framework 并且我也在构建一个停止在这里工作的其他人的代码，所以我遇到了一些麻烦...
我正在尝试创建 Web 表单以将数据提交到数据库，但收到错误消息 'UserView' object has no attribute 'object'

在这里查看类似的帖子我看到它被提到如果你覆盖 post 那么你需要将 object 分配给视图，但我尝试在 [=21] 中添加 object = self.get_object() =] 并且刚刚得到一个 QuerySet 错误...
这似乎也在Traceback中突出显示，我提交的表格无效？我输入了 "valid" 数据，所以我可能需要实施某种验证过程？:

这是 django/views/generic/edit.py 中 BaseCreateView 的 post 函数：
def post(self, request, *args, **kwargs):
self.object = None
return super(BaseCreateView, self).post(request, *args, **kwargs)
如果您覆盖函数，您应该调用 super .. 或在您的代码中包含 self.object = None。
