Question

我在尝试将dev db移动到生产时遇到此错误。 Django dumpdata和loaddata还不够，所以我试图将postgresql的pg_dump转换为.sql文件，然后删除生产数据库并使用命令创建一个新的数据库

sql create database dbname;
sql dbname < dumpfile.sql

该网站现在显示在我的生产服务器上（有一些缺少的css表），数据在数据库中。我无法弄清楚为什么有些css表没有显示（它们在服务器上），当我尝试在我的服务器上运行manage.py migrate时，我得到了这个追溯...

做了一些搜索，找不到答案，我不知道下一步该转到哪里。

Answer 1

它必须与迁移有关我不太确定它是如何工作的，但我的开发版本有一组不同于我的生产（我认为这是正常的，不完全确定??）

所以我在这种情况下要做的就是删除旧数据库，创建新数据库，从生产服务器运行manage.py migrate，然后输入转储的dbdata，一切正常。
