我正在为我的其他网站建立一个处理数据库和电子邮件营销数据的API。
我有一个从数据库和ActiveCampaign中删除用户的端点，为了防止错误地发出任何删除请求，我正在检查请求正文中是否有key:value对，如果是'delete': true，继续，如果不是，我想返回一个带有状态代码的错误消息，让我（或其他我将来可能包含在项目中的代码）知道错误是什么。
我的是：当检查是否有一个名为'delete'的键时，我得到一个错误，我的程序停止工作。
我想知道是否有一种方法可以在检查之后只“做一些事情”，但不会破坏我的程序，如果发生了一些意料之外的事情，它会向请求源发送一个错误。
下面是我尝试使用的类/函数：

class Leads(APIView):
    @staticmethod
    def delete(request):
        if request.data["delete"]:
            delete_from_db = Lead.objects.filter(email=request.data["email"])
            lead = LeadHelper(email=request.data["email"] if request.data["email"] else "")
            lead.delete_from_activecampaign()
            return Response([delete_from_db], status=status.HTTP_200_OK)
        else:
            payload = {
                "message": "Denied because 'delete': 'true' was not found in request, did you sent this by error?"
            }
            return Response(payload, status=status.HTTP_401_UNAUTHORIZED)

我的主要问题是，如果没有'delete'键，它甚至不能运行else语句
下面是错误：
