Python 在django视图中使用queryset Q时出错

我正在使用Q创建动态查询集 当我打印的时候

build_query[:-1]

我得到了输出

Q(owner_id=1)|Q(assigned_to=1)

但是当用这个来

consultants = Consultant.objects.filter(*build_query[:-1])

获取的错误值太多，无法解压缩 我用**和*试过了，但还是不起作用。 当我检查

print type(build_query[:-1])

我得到了字符串类型。这是主要原因吗

consultants=Consultant.objects.filter（*build\u query[：-1]）

您是否尝试过：

Consultant.objects.filter（*[build_query[：-1]，]））

args应该是一个列表
