如何在 django-filters 中实现日期范围过滤器

Question

我想在日期范围内筛选 upload_date (upload_date__lte, upload_date__gte) 我的模特是

class MetaData(models.Model):
    # Video Info
    tag = models.CharField(max_length=100, default="")
    category = models.CharField(max_length=100, default="")
    upload_date = models.DateField()
    upload_time = models.TimeField()
    caption = models.CharField(max_length=2000, blank=True, default='Not Set')
    comments = models.IntegerField()
    likes = models.IntegerField()
    shourtcode = models.CharField(max_length=200, default='', unique=True)
    owner_id = models.PositiveIntegerField(default=0)
    # Post
    link = models.URLField(unique=True)
    user = models.ForeignKey(
        User, on_delete=models.SET_NULL, null=True, blank=True)
    status = models.CharField(max_length=20, choices=(
        ('Pending', 'Pending'), ('Acquired', 'Acquired'), ('Rejected', 'Rejected'), ('Approved', 'Approved')), default='Pending')
    public = models.BooleanField(default=False)
    date = models.DateTimeField(auto_now_add=True)

我的看法是

class FetchMetaData(ListCreateAPIView):
    queryset = MetaData.objects.all()
    serializer_class = s.MetaDataSerializer
    name = 'metadata-list'
    pagination_class = DefaultPagePagination
    filter_backends = [DjangoFilterBackend, SearchFilter, OrderingFilter]

    filter_fields = (
        "tag",
        "category",
        "public",
        "status",
        "user",
        "upload_date",

    )
    ordering_fields = (
        '-upload_date',
        '-upload_time',
        'likes',
        'comments',
    )
    search_fields = (
        "$tag",
        "$caption",
        "$category"
    )
    ordering = ['-upload_date']

我要的是过滤范围在upload_date

喜欢http:///localhost/tags/filterMetadata/?upload_date__lte=2022-01-05?upload_date__gte=2022-01-05

我认为您需要创建 MetaDataFilter。

from django_filters import rest_framework as filters

class MetaDataFilter(filters.FilterSet):
    upload_date = filters.DateFromToRangeFilter()

    class Meta:
        model = MetaData
        fields = ['upload_date']

在视图中，可以设置filterset_class

class FetchMetaData(ListCreateAPIView):
    ...
    filterset_class = MetaDataFilter

那么，api url 应该是 .../filterMetadata/?upload_date_before=2022-01-05&upload_date_after=2022-01-05.
