python - 无法将 postgresql 与 django 连接

Question

我在 postgresql 中创建了一个名为 testdb1 的数据库，我正在尝试将它与我的 django 应用程序连接。但是当我运行 python manage.py syncdb 时，我收到错误 django.db.utils.OperationalError: FATAL: database "testdb1"does not exist。该数据库确实存在，因为它已通过以下内容确认:

archit@archit-Inspiron-5520:~/Documents/DjangoLabs/gswd$ psql -U postgres
Password for user postgres: 
psql (9.1.14)
Type "help" for help.

postgres=# \connect testdb1
You are now connected to database "testdb1" as user "postgres".
testdb1=# \d
          List of relations
 Schema |  Name   | Type  |  Owner   
--------+---------+-------+----------
 public | company | table | postgres
(1 row)

在 settings.py 我有:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'testdb1',                      
        'USER': 'postgres',
        'PASSWORD': 'admin',
        'HOST': 'localhost',
        'PORT': '',
    }
}

在 /etc/postgresql/9.1/main/pg_hba.conf 中:

# Database administrative login by Unix domain socket
local   all             postgres                                md5

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     md5
# IPv4 local connections:
host    all             all             127.0.0.1/32            md5
# IPv6 local connections:
host    all             all             ::1/128                 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local   replication     postgres                                peer
#host    replication     postgres        127.0.0.1/32            md5
#host    replication     postgres        ::1/128                 md5
local   all         postgres                          md5

编辑:

\du 命令给出:

testdb1=# \du
                             List of roles
 Role name |                   Attributes                   | Member of 
-----------+------------------------------------------------+-----------
 archit    | Superuser, Create role, Create DB, Replication | {}
 postgres  | Superuser, Create role, Create DB, Replication | {}

如有任何帮助，我们将不胜感激。

删除数据库并重新创建数据库。

在 settings.py 中写入 'PORT'='5432' 或 '5433' 因为这是所有 postgresql 中的公共(public)端口。

然后做syncdb或者migrate。
