为了使它更灵活，你可以这样设计一个FilterBackend:

class AnalyticsFilterBackend(generic_filters.BaseFilterBackend):
    def filter_queryset(self, request, queryset, view):
        predicate = request.query_params # or request.data for POST

        if predicate.get('from_date', None) is not None and predicate.get('to_date', None) is not None:
            queryset = queryset.filter(your_date__range=(predicate['from_date'], predicate['to_date']))

        if predicate.get('from_date', None) is not None and predicate.get('to_date', None) is None:
            queryset = queryset.filter(your_date__gte=predicate['from_date'])

        if predicate.get('to_date', None) is not None and predicate.get('from_date', None) is None:
            queryset = queryset.filter(your_date__lte=predicate['to_date'])
        return queryset

你可以使用django的datetime过滤器。日期对象:

import datetime
samples = Sample.objects.filter(sampledate__gte=datetime.date(2011, 1, 1),
                                sampledate__lte=datetime.date(2011, 1, 31))

为了使它更灵活，你可以这样设计一个FilterBackend:

class AnalyticsFilterBackend(generic_filters.BaseFilterBackend):
    def filter_queryset(self, request, queryset, view):
        predicate = request.query_params # or request.data for POST

        if predicate.get('from_date', None) is not None and predicate.get('to_date', None) is not None:
            queryset = queryset.filter(your_date__range=(predicate['from_date'], predicate['to_date']))

        if predicate.get('from_date', None) is not None and predicate.get('to_date', None) is None:
            queryset = queryset.filter(your_date__gte=predicate['from_date'])

        if predicate.get('to_date', None) is not None and predicate.get('from_date', None) is None:
            queryset = queryset.filter(your_date__lte=predicate['to_date'])
        return queryset

Use

Sample.objects.filter(date__range=["2011-01-01", "2011-01-31"])

或者如果你只是想按月份过滤:

Sample.objects.filter(date__year='2011', 
                      date__month='01')

Edit

正如Bernhard Vallant所说，如果你想要一个排除指定范围结束的查询集，你应该考虑他的解决方案，它使用gt/lt(大于/小于)。

很简单,

YourModel.objects.filter(YOUR_DATE_FIELD__date=timezone.now())

对我有用

模型

date = models.DateField()

View

def get_queryset(self):  

    fromDate = self.request.query_params.get('fromDate',None)
    toDate = self.request.query_params.get('toDate',None)
    response  = yourModel.objects.filter(date__gte=fromDate,date__lte=toDate)
    return response
