Django：在 'simple_history' 包中注册 'User' 模型时遇到问题

Question

场景：

我在 Django 中使用 simple_history 包。

在文档的高级用法部分，“History for a Third-Party Model”表示，

" To track history for a model you didn’t create, use the simple_history.register utility. You can use this to track models from third-party apps you don’t have control over. Here’s an example of using simple_history.register to history-track the User model from the django.contrib.auth app"

所以我将该代码放在 models.py 中（也尝试了 admin.py），如下所示：

from simple_history import register
from django.contrib.auth.models import User

register(User)

问题: 当我运行 python manage.py makemigrations 它给出以下错误：

E:! Project\CMIT\CMITv0101\cmit001>python manage.py makemigrations
Migrations for 'auth':
C:\Program Files\Python36\lib\site-packages\django\contrib\auth\migrations[=13=]09_historicaluser.py

PermissionError: [Errno 13] Permission denied: 'C:\Program Files\Python36\lib\site-packages\django\contrib\auth\migrations[=13=]09_histo
ricaluser.py'

我现在可以做什么来注册我的用户模型？

Answer 1

根据错误描述，您无权更改文件夹 C:\Program Files\Python36\lib\site-packages\django\contrib\auth\migrations

更改文件夹的读取、写入和执行权限。一旦完成，运行python manage.py makemigrations

此外，您正在尝试在系统包中进行迁移。您可以在单独的应用程序中创建自定义用户模型，然后在那里进行迁移。
