Question

我一直在遵循Django girls教程来学习Django Web框架。我已达到本教程的this part。现在，当我运行命令python manage.py migrate时，我完全陷入了困境。我什至不能再在本地主机上运行服务器，runserver会带来同样的错误。自从我更改settings.py文件以容纳Postgres数据库以来，所有这些错误开始出现。我非常需要帮助。

我从以前（版本11.4）安装了postgres。看到这些错误后，按照上述教程的说明，我将其删除，然后再次下载。这是无用的努力，因为出现了同样的问题。

Traceback (most recent call last):  File "/home/jpsofficedev/Documents/coding_for_girls/djangogirls/myvenv/lib64/python3.7/site-packages/django/db/backends/base/base.py", line 216, in ensure_connection

    conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
psycopg2.OperationalError: FATAL:  Ident authentication failed for user "jpsofficedev"

settings.py中的数据库设置

      'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'djangogirls',
        'USER': 'jpsofficedev',
        'PASSWORD': '',
        'HOST': '127.0.0.1',
        'PORT': '',
    }
}

我在Postgres的经验为空。对于某些教程和文档的建议也将不胜感激。

谢谢您的链接@DEEPAK KUMAR https://serverfault.com/questions/406606/postgres-error-message-fatal-ident-authentication-failed-for-user。我点击了此链接，并更改了

host all all 127.0.0.1/32 ident

到

host all all 127.0.0.1/32 trust 在pg_hba.conf文件中。这解决了我面临的问题。

当我运行命令“ python manage.py migration”时无法理解错误
