my settings.py for DB的外观:
ALLOWED_HOSTS = ['*']
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'fishercoder',
'USER': 'fishercoderuser',
'PASSWORD': 'password',
'HOST': 'localhost',
'PORT': '5432',
}
}
我通过以下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,通过运行:psql -U postgres fishercoder < fishercoder_dump.sql
,我成功地将另一个SQL转储导入到这个新数据库中
然后我尝试在这个EC2实例上运行我的Django项目./manage.py makemigrations
,但出现了以下错误:
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
我在上面找到了这三个相关的帖子: One、{a2}和{a3}
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
运气不好,然后我重新启动了我的postgresql数据库:sudo service postgresql restart
当我再次尝试运行迁移时,仍然面临相同的错误
更多调试信息如下:
ubuntu@ip-xxx-xxx-xx-xx:~$ psql -U postgres

有没有办法解决这个问题
请尝试使用下面的命令,这对我有效
