我正在为我的 django 项目构建一个注册表单，并且为了设计它，我使用了脆脆的表单。但是，当我运行服务器并转到注册页面时，我看到以下错误：

    Internal Server Error: /users/register/
Traceback (most recent call last):

我正在使用 Windows PowerShell。但是，我不知道为什么，当我尝试激活 python 虚拟环境时，出现此错误：

venv\Scripts\activate : File C:\Users\Dell\Desktop\flask\microblog\venv\Scripts\Activate.ps1 
cannot be loaded because running scripts is disabled on this system. For more information, see

这是我运行的命令：

venv\Scripts\activate

这是第一次发生。问题是什么？

SystemCheckError: System check identified some issues:

ERRORS:
blog.Post: (models.E014) 'ordering' must be a tuple or list (even if you want to order by only one field).

这是我的models.py文件：

from django.db import models
from django.utils import timezone
from django.contrib.auth.models import User

class Post(models.Model):
    STATUS_CHOICES = (
        ('draft','Draft'),
        ('published','Published')
    )
    title = models.CharField(max_length=250)
    slug = models.SlugField(max_length=250,unique_for_date='publish')
    author = models.ForeignKey(User,on_delete=models.CASCADE,related_name='blog_posts')
    body = models.TextField()
    publish = models.DateTimeField(default=timezone.now)
    created = models.DateTimeField(auto_now_add=True)
