将模型迁移到 SQL Server 时出现 Keyerror“include”

Question

我有一个 Django 应用程序，后端为 Microsoft sql 服务器。为此，我安装了“pip install django-mssql-backend”。

我扩展了用户模型并添加了一个额外的确认密码字段，我正在迁移，但我遇到了以下错误

    return self.template % self.parts
KeyError: 'include'

之后，我可以看到下面在数据库中创建的两个表

1. django_migrations
2. django_内容_类型

我的模型如下：

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

class UserMaster(models.Model):
    user = models.OneToOneField(User, on_delete = models.CASCADE)

    # Additional fields
    confirm_password = models.CharField(max_length=10)

    def __str__(self):
        return self.user.username

下面是Forms.py

from django import forms
from django.contrib.auth.models import User
from retail_forms.models import UserMaster

class UserForm(forms.ModelForm):
    password = forms.CharField(widget = forms.PasswordInput())
    first_name = forms.CharField(required=True)
    last_name = forms.CharField(required=True)

    class Meta():
        model = User
        fields = ('first_name','last_name','email','username','password')

class UserMasterForm(forms.ModelForm):
    confirm_password = forms.CharField(required=True)
    class Meta():
        model = UserMaster
        fields = ('confirm_password',)

有人可以帮忙吗。

此问题已在 . 的预发行版本 1.0rc1 中修复mssql-django。GitHub问题

我建议使用mssql-djangoover django-pyodbc,django-pyodbc-azure-2019或django-mssql-backend。因为它受到微软的支持并且在我看来有更好的支持。

修理：

1. 安装 mssql-djangopip install mssql-django==1.0rc1
2. 更改数据库引擎settings.py

DATABASES = {
        'default': {
            'ENGINE': 'mssql',
            ...
        }
    }
