如何为模型中的dateField创建月/年的django-filter自定义过滤器？

from django_filters import FilterSet, DateFilter
from .models import YourModel

class YourModelFilter(FilterSet):
    month = DateFilter(field_name='dateField', lookup_expr='month')
    year = DateFilter(field_name='dateField', lookup_expr='year')

    class Meta:
        model = YourModel
        fields = []

from .filters import YourModelFilter

def your_view(request):
    queryset = YourModel.objects.all()
    filter = YourModelFilter(request.GET, queryset=queryset)
    filtered_queryset = filter.qs
    # 其他处理逻辑
