What are some basic steps for troubleshooting and narrowing down the cause for the "django.db.utils.ProgrammingError: permission denied for relation django_migrations" error from Django?

我在最初是稳定的生产服务器之后收到了此消息，但此后对Django，Postgres，Apache和Github的一些方面进行了一些更改。此外，距离进行这些更改已经有一段时间了，我不记得或无法跟踪可能导致问题的每一个更改。

I'm getting this message after what was initially a stable production server but has since had some changes to several aspects of Django, Postgres, Apache, and a pull from Github. In addition, it has been some time since those changes were made and I don't recall or can't track every change that may be causing the problem.

当我运行 python manage.py runserver 或其他任何 python manage.py ... 命令（ python manage.py check ，它表示系统很好。

I get the message when I run python manage.py runserver or any other python manage.py ... command except python manage.py check, which states the system is good.

推荐答案

I能够根据此问题。基本上，需要将PostgreSQL特权重新授予db用户。就我而言，那是我在虚拟环境设置文件中设置的用户。从命令行（或在postgres中）运行以下命令，其中 mydatabase 和 dbuser 应该是您自己的数据库和用户名：

I was able to solve my issue based on instructions from this question. Basically, postgres privileges needed to be re-granted to the db user. In my case, that was the user I had setup in the virtual environment settings file. Run the following from the commandline (or within postgres) where mydatabase and dbuser should be your own database and user names:

psql mydatabase -c "GRANT ALL ON ALL TABLES IN SCHEMA public to dbuser;"
psql mydatabase -c "GRANT ALL ON ALL SEQUENCES IN SCHEMA public to dbuser;"
psql mydatabase -c "GRANT ALL ON ALL FUNCTIONS IN SCHEMA public to dbuser;"
