我很难用postgres设置django。
这是我的settings.py:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'HOST': 'localhost',
'NAME': 'collector',
'USER': 'collector_user',
'PASSWORD': 'collector'
}
}
我在Postgres First步骤网站中创建了带有密码收集器的用户collector_user。还创建了收集器模式:
postgres=# select nspname from pg_catalog.pg_namespace;
nspname
--------------------
pg_toast
pg_temp_1
pg_toast_temp_1
pg_catalog
public
information_schema
collector
(7 rows)
以下是django对此的评价:

我也试过删除数据库和用户并尝试再次创建它。它也没有用。可能是什么问题?有没有我没做过的事情?我是postgres的新手,我正常使用MySQL。
答案 0 :(得分:4)
在PostgreSQL中,架构不是数据库。您在名为“postgres”的数据库中创建了名为“collector”的模式。但是您尝试连接到名为“collector”的数据库。哪个不存在,因为你没有创建它。你应该创建一个名为'collector'的数据库,然后只保留模式(即默认为'public')。
在'postgres'数据库中创建新模式通常是一种不好的做法,因为名为'postgres'的数据库通常应保留用于系统维护任务。
