psycopg2.errors.InsufficientPrivilege：关系 django_migrations 的权限被拒绝

Question

我的数据库 settings.py 是什么样子的：

ALLOWED_HOSTS = ['*']

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'fishercoder',
        'USER': 'fishercoderuser',
        'PASSWORD': 'password',
        'HOST': 'localhost',
        'PORT': '5432',
    }
}

我以这种方式创建了一个名为“fishercoder”的新的空数据库：

psql -U postgres
create database fishercoder; 
ALTER USER postgres with password 'badpassword!'; 
CREATE USER fishercoderuser WITH PASSWORD 'password';
ALTER ROLE fishercoderuser SET client_encoding TO 'utf8';
ALTER ROLE fishercoderuser SET default_transaction_isolation TO 'read committed';
ALTER ROLE fishercoderuser SET timezone TO 'PST8PDT';
GRANT ALL PRIVILEGES ON DATABASE fishercoder TO fishercoderuser;

然后我通过运行将我的其他 SQL 转储成功导入到这个新数据库中： psql -U postgres fishercoder < fishercoder_dump.sql

然后我尝试在此 EC2 实例上的 Django 项目上运行./manage.py makemigrations ，但出现此错误：

Traceback (most recent call last):
  File "/home/ubuntu/myprojectdir/myprojectenv/lib/python3.6/site-packages/django/db/backends/utils.py", line 86, in _execute
    return self.cursor.execute(sql, params)
psycopg2.errors.InsufficientPrivilege: permission denied for relation django_migrations

我在 SO 上找到了这三个相关帖子： 一、 二和三

我尝试了他们建议的命令：

postgres=# GRANT ALL ON ALL TABLES IN SCHEMA public to fishercoderuser;
GRANT
postgres=# GRANT ALL ON ALL SEQUENCES IN SCHEMA public to fishercoderuser;
GRANT
postgres=# GRANT ALL ON ALL FUNCTIONS IN SCHEMA public to fishercoderuser;
GRANT

不走运，然后我重新启动了我的 postgresql db: sudo service postgresql restart当我再次尝试运行迁移时，仍然面临同样的错误。

更多调试信息如下：

任何想法如何解决这一问题？

Answer 1

恢复数据库后，所有表都将归 postgres 用户所有。

你需要做这个补助金：

GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO <user>;

我遇到了同样的问题并解决了。

您还需要向 Django 用户授予其他权限：

GRANT USAGE, SELECT ON ALL SEQUENCES IN SCHEMA public TO <user>;

Answer 2

请尝试使用以下命令，这对我有用

GRANT rds_superuser TO username;

Answer 3

我有以下错误。

psycopg2.errors.InsufficientPrivilege：表 django_migrations 的权限被拒绝

授予我正在使用的超级用户“postgres”的权限。

对我来说，这个命令有效：

GRANT postgres TO <user>;
