在django视图中使用queryset Q时出错

Question

我正在使用Q创建动态查询集当我打印

时

build_query[:-1]

我得到输出

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

，但是当使用

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

得到一个错误，太多的值无法解包我用**试过，没有**仍然不起作用。当我检查

的类型

print type(build_query[:-1])

我正在获取字符串类型。这是主要原因吗?

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

Answer 1

你试过了吗?

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

参数应该是一个列表
