Django rest framework 是否可以将查找表达式不为'的搜索筛选器与FillterSet筛选器相结合；确切的？

我想将搜索过滤器与没有git标准查找表达式的FIlterSet过滤器结合起来

我尝试为我的端点添加此配置：

filter_backends = (filters.SearchFilter, DjangoFilterBackend)
    search_fields = ('username', 'full_name')
    filterset_fields = 'username',

它工作正常，但我需要在

filterset\u字段中查找
username

这是我的终点

class UsersAPIView(generics.ListAPIView):
    serializer_class = CreatorSerializer
    filter_backends = (filters.SearchFilter, DjangoFilterBackend)
    search_fields = ('username', 'full_name')
    filterset_fields = 'username',
    queryset = User.objects.all()

    #filter_class = UserFilter

和我的过滤器：

class UserFilter(filters.FilterSet, ):
    username = filters.CharFilter(field_name='username', lookup_expr='startswith')

    class Meta:
        model = User
        fields = 'username',

如果我开始使用UserFilter，则SearchFilter将被禁用
