使用Heroku拒绝关系django_migrations的权限 [英] Permission denied for relation django_migrations using Heroku

问题描述

当尝试在Heroku上使用django迁移数据库更改时，我得到：

While attempting to migrate database changes using django on Heroku, I get:

psycopg2.ProgrammingError: permission denied for relation django_migrations

其他人已经可以通过授予适当的特权来解决此问题（例如，有关关系的权限被拒绝）。不幸的是，我无法在Heroku的爱好层上授予权限或创建新用户。

Other people have been able to resolve this issue by granting the appropriate privileges (e.g., Permission denied for relation). Unfortunately, I can't grant permissions or create a new user on the Heroku hobby tier.

我能够回滚一些迁移，但最终得到了： / p>

I was able to roll back a few migrations, but eventually I got:

django.db.utils.ProgrammingError: table "labs_branch_tests" does not exist

，并且无法迁移回较新的迁移。

and could not migrate back to newer migrations.

推荐答案

我能够通过在postgres终端中向用户授予特权来解决此问题。

I was able to get around this by granting privileges to the user in the postgres terminal.

首先通过Heroku CLI（ heroku pg：psql ）连接到postgres。

First connect to postgres through the Heroku CLI (heroku pg:psql).

这很笨拙，但得到您的Heroku postgres用户名，方法是在postgres终端中调用 \c 。 （输出的最后一行将是您现在以用户USERNAME的身份连接到数据库DATABASE_NAME 。）

This is clunky but get your Heroku postgres username by calling \c in the postgres terminal. (The last line of output will be You are now connected to database DATABASE_NAME as user USERNAME.)

然后授予

GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public to USERNAME;
GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA public to USERNAME;
GRANT ALL PRIVILEGES ON ALL FUNCTIONS IN SCHEMA public to USERNAME;
