如何从TimeStampedModel显示在管理面板中创建的内容

Question

尝试跟随https://github.com/jazzband/django-model-utils/issues/186

#admin.py

class CompanyAdmin(admin.ModelAdmin):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.readonly_fields += (
            "created",
            "modified",
        )

错误

django_1        | SystemCheckError: System check identified some issues:
django_1        | 
django_1        | ERRORS:
django_1        | <class 'meetings.admin.CompanyAdmin'>: (admin.E035) The value of 'readonly_fields[0]' is not a callable, an attribute of 'CompanyAdmin', or an attribute of 'meetings.Company'.
django_1        | <class 'meetings.admin.CompanyAdmin'>: (admin.E035) The value of 'readonly_fields[1]' is not a callable, an attribute of 'CompanyAdmin', or an attribute of 'meetings.Company'.

如何使用django- created -utils在管理面板中显示模型值？

Answer 1

根据错误，看起来created和modified不是模型(meetings.Company)的属性。

是否确定已将这些字段添加到Company模型中。

如果这不能解决你的问题，你能将你的模型添加到问题中吗？
