获取或创建对象时遇到一个奇怪的错误

get_or_create()

build_case函数

ValueError: Cannot assign "(<CaseStatus: CaseStatus object (13)>,)": "PatientCase.status" must be a "CaseStatus" instance.

    status, created = CaseStatus.objects.get_or_create(

    return status

Answer 1

在视图中检查status_data['message']。看起来好像是元组(<CaseStatus: CaseStatus object (13)>,)而不是状态对象<CaseStatus: CaseStatus object (13)>。

您的代码中可能包含逗号，从而使status成为元组，例如：

status = CaseStatus(...),

尽管如此，我们不能告诉您，因为您没有包括完整的回溯或设置status_data的其余代码。

Django get_or_create（）返回奇怪的行为
