Django 1.7 django.db.utils.OperationalError：没有这样的表：auth_customuser

【问题描述】：

通过新的迁移将大型 1.6 项目迁移到 1.7 感到非常难过。我现在可以使用 makemigrations 和 migrate 重新创建数据库，但是当我尝试运行测试时，我收到关于 auth_customuser 的错误。我正在使用自定义用户，但它在我的网络应用程序中，并且不称为 customuser。

这是运行测试的输出，带有一些打印语句来尝试找出发生了什么：

在寻找什么 auth_customuser？

查看代码目录

$ grep -r "customuser" *
Binary file :gmd_test_db: matches

查看虚拟环境

(gmd)$ grep -r "customuser" *
lib/python2.7/site-packages/django/contrib/auth/fixtures/custom_user.json:        "model": "auth.customuser",
lib/python2.7/site-packages/django/contrib/auth/tests/test_decorators.py:        # Add permissions auth.add_customuser and auth.change_customuser

因此，在 require_permission 装饰器中添加一些跟踪信息，但它从未被触发，因为我希望它在测试套件中。

所以我现在已经没有想法了。这一定是我的问题，因为没有其他人报告过这个错误，我只是想不出去哪里看......

要求：

Django==1.7.1
MySQL-python==1.2.5
Pillow==2.6.1
South==1.0.1
Unidecode==0.04.16
argparse==1.2.1
django-crontab==0.6.0
django-facebook==6.0.2
django-google-maps==0.2.3
django-nose==1.3
django-paypal==0.1.5
django-taggit==0.12.2
django-tastypie==0.12.1
jsonfield==1.0.0
mock==1.0.1
nose==1.3.4
python-dateutil==2.3
python-mimeparse==0.1.4
pytz==2014.10
qrcode==5.1
requests==2.5.0
six==1.8.0
wsgiref==0.1.2

项目中还有以下应用程序，因为它们的时间很小

lazysignup
django-registration

【问题讨论】：

  • django 1.7.x 完整版？
  • 你能分享你的需求吗（包、版本和/或 github url）
  • django 1.7.1 并添加了要求。
  • 看起来在你的测试夹具中，你有一个“auth_customuser”表——它可能是旧的东西。您可以重新创建测试夹具 JSON 文件而不转储身份验证表吗？
  • 你在INSTALLED_APPS有什么？

标签： django testing


【解决方案1】：

我想答案就在这里：

https://code.djangoproject.com/ticket/19495

看起来您在项目中有一个名为auth 的应用程序，这与django.contrib.auth 冲突如上面的票证中所述，应用程序路径的最后一段，即auth 必须是在您项目中使用的所有应用程序（包括 Django 自己的应用程序）中唯一。

所以当你运行测试时，Django 会找到夹具django/contrib/auth/fixtures/custom_user.json（Django 自带）。但它会感到困惑并尝试将其加载到 您的 auth 应用的模型而不是 django.contrib.auth 模型。

您应该将您的 auth 应用重命名为独特的名称。

【讨论】：

  • 不完全是，但差不多。由于某种早已被遗忘的原因，在测试套件中发现了这条流氓行。 from django.contrib.auth.tests.custom_user import CustomUser 现在它又可以工作了！
