在那里找到了答案： https ://django-filter.readthedocs.io/en/master/guide/usage.html#declaring-filters

class PersonFilter(django_filters.FilterSet):

    dob_year = django_filters.NumberFilter(field_name='dob', lookup_expr='year')

    class Meta:
        model = Person
        fields =  ['first_name','last_name','dob',]
