Question

我正在编写一个导入脚本，以便在我的Django网站中将CSV格式化为模型。我希望这些创作出现在Django管理员的“历史”中，所以我写了这个函数，应该记录对象的创建。

from django.contrib.admin.models import LogEntry, ADDITION
def log_creation(created_object, message, uid=1):
    #Doesn't work :(
    LogEntry.objects.log_action(
            user_id=uid,
            content_type_id=get_content_type_for_model(created_object).pk,
            object_id=created_object.pk,
            object_repr=force_text(created_object),
            action_flag=ADDITION,
            change_message=message
        )

我大部分都是在管理员中将其复制出this built in function。

但是，如果我使用新创建的对象作为输入运行它，我会收到此错误

知道如何避免这种情况吗？

获取错误运行LogEntry.log_action（）时无法解析相关模型'auth.User'
