我的settings.py文件中数据库相关的部分长这样:
ALLOWED_HOSTS = ['*']
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'fishercoder',
'USER': 'fishercoderuser',
'PASSWORD': 'password',
'HOST': 'localhost',
'PORT': '5432',
}
}
我这样创建了一个名为“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;
我成功地通过以下命令将另一个 SQL 转储文件导入到新的数据库中:psql -U postgres fishercoder < fishercoder_dump.sql
然后我尝试在这个 EC2 实例上运行 ./manage.py makemigrations
命令,但是出现了以下错误:
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 Stack Overflow 上找到了三篇相关的帖子:第一篇,第二篇 和 第三篇。
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
没什么运气,于是我重启了我的postgresql数据库:sudo service postgresql restart
当我再次尝试运行迁移时,仍然面临着相同的错误。
以下是更多的调试信息:

有什么办法可以解决这个问题吗?
