python - Django 管理站点不显示模型的默认权限

Question

我的 Django 管理站点不显示任何模型的任何默认权限。实际上，我检查了数据库，在 auth_permissions 表中找不到任何模型权限。

我已经运行了 python manage.py makemigrations 和 python manage.py migrate。我还尝试删除数据库和迁移文件并再次运行上面的两个命令，但不起作用。我已经在 admin.py 中注册了我的模型。

我可以尝试其他解决方案吗？

admin.py

from django.contrib import admin
from .Models import *


# Register your models here.

admin.site.register(LeaveRequest)
admin.site.register(Worker)
admin.site.register(TimeSheet)

Answer 1

在您的 admin.py 中，您将所有模型导入为 from .Model import *。如果您没有将 models.py 文件作为 Models.py 进行操作，Python 是一种区分大小写的编程语言。

我想 from .models import * 就可以了
