Question

当尝试在Django中执行syncdb时，它会失败并显示跟踪回溯。我尝试删除架构并创建一个干净的架构。 migrate会创建迁移，但它永远不会创建django_migrations之外的任何表。我还删除了所有现有的pyc文件作为预防措施，但没有运气。它似乎没有在初始同步时创建任何表。目前没有处理创建的核心表之外的任何模型（auth，sessions等）

Answer 1

我在Django 1.8中遇到了这个问题，我正在使用自定义用户配置文件，我在文档中建议使用OneToOneField为用户创建。

幸运的是，我将用户个人资料代码隔离在一个名为“个人资料”的单独应用中。

对我来说，这种解决方法解决了这个问题：

禁用自定义用户个人资料，方法是在settings.py中禁用“个人资料”应用，方法是将其从INSTALLED_APPS中删除
运行python manage.py migrate
重新插入应用程序重新启用自定义用户个人资料。

这肯定是由于Django中的一个错误。

Answer 2

我有类似的问题。最后，我发现并非所有应用都有迁移功能。因此，请检查具有models.py文件的所有已安装应用程序（Django项目明智）是否也具有迁移功能。这解决了我的问题（强制Django为特定应用程序创建迁移），还检查列出了migrations.swappable_dependency(settings.AUTH_USER_MODEL),以及迁移依赖项中的第一个位置。

Answer 3

我使用之前版本的django（1.5）设置的多个数据库发生此错误。升级没有带到南方的多个数据库。最终我将不得不重新访问这个以便我可以尝试迁移，但与此同时我已经废弃了这个。删除settings.py中的多个数据库实例解决了这个问题。

django.db.utils.ProgrammingError：relation＆＃34; auth_user＆＃34;不存在
