我有一个日历应用程序，该应用程序具有Event，title，description，start_time，end_time字段的choices类。我通过两个选择添加了choices字段
c =[("1", "経理部"), ("2", "管理部")]
我还为此类向User模型添加了一列
class Employee(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
department = models.CharField(max_length=100)
我可以使用此代码访问该部门field
>>> from django.contrib.auth.models import User
>>> u = User.objects.get(username='marcel4')
>>> d = u.employee.department
>>> print(d)
>>> 経理部
我只是想在日历应用程序中选择“ with理部”保存一个帖子（事件），并且只能使用将department设置为“経理部”（相同的）的帐户才能看到该帖子。我应该改变吗？ （例如if左右
这是我的密码
