django，如何从get_or_create获取对象并将其用于其他get_or_create？

Question

代码示例：

keyword = Keyword.objects.get_or_create(text=text)

sub_keyword = SubKeyword.objects.get_or_create(keyword=keyword, user=request.user)

它返回：TypeError: int() argument must be a string, a bytes-like object or a number, not 'Keyword'

来自行：sub_keyword = SubKeyword.objects.get_or_create(keyword=keyword, user=request.user)

该怎么做？

Answer 1

keyword, created = Keyword.objects.get_or_create(text=text)

sub_keyword, created = SubKeyword.objects.get_or_create(keyword=keyword.id, user=request.user)

get_or_create返回类似(object, created)的元组。这就是为什么您有AttributeError的原因。请参阅get_or_create文档
