python - 在 Django 中将 Postgres 与 Oscar 同步的编程错误

Question

我正在学习 OSCAR 教程 (http://django-oscar.readthedocs.org/en/latest/internals/getting_started.html)，并试图让 Haystack 与 Solr 一起工作。我已经设置了 postgres。我在 Cloud9 上运行。我尝试运行“$ python manage.py syncdb --noinput”这最终在运行迁移时被杀死...

我也试过在没有 --noinput 的情况下运行它

如果我尝试运行服务器，它表明数据库未同步...当我尝试加载页面时，我得到这个...

我有点搞不懂这是什么意思。似乎我在同步数据库时遇到了问题......而且似乎只是某种错误超出了我的范围。我什至不确定我可以将哪些文件复制到这里会有帮助。最好的我可以告诉 Django 正在访问 postgres ......并且由于一些奇怪的原因它没有同步。

Answer 1

删除数据库，删除迁移，然后根据需要运行 syncdb 或 makemigrations。可能这会有所帮助。 如果它不起作用，请向我展示您的模型文件。
