Question

我想计算Django中两个日期之间的天差。我正在尝试这段代码：

我的模特：

dateDeDebut = models.DateTimeField(auto_now_add=False, auto_now=False)
dateDeFin = models.DateTimeField(auto_now_add=False, auto_now=False)

我的classViewSet：

class MyClassViewSet(viewsets.ModelViewSet):
    serializer_class = MyClassSerializer
    permission_classes = (IsAuthenticated, )

    def perform_create(self, serializer):
        if (condition):
            diff = (self.request.data.get('dateDeFin') - self.request.data.get('dateDeDebut')).days #never executed
        print(diff)

我收到了这个错误：

unsupported operand type(s) for -: 'unicode' and 'unicode'

Answer 1

此解决方案适合我

class MyClassViewSet(viewsets.ModelViewSet):
    serializer_class = MyClassSerializer
    permission_classes = (IsAuthenticated, )

    def perform_create(self, serializer):
        if (condition):
            start_date = datetime.datetime.strptime(self.request.data.get('dateDeFin'), "%Y-%m-%d %H:%M")
            end_date = datetime.datetime.strptime(self.request.data.get('dateDeDebut'), "%Y-%m-%d %H:%M")
            diff = abs((end_date-start_date).days)
        print(diff)
