Django 1.9.2 AssertionError:数据库连接未设置为UTC

Question

我现在已经使用PostgreSQL设置了3台服务器,到目前为止还没有看到这个问题.我现在正在设置第一台没有在丹麦服务器上运行的服务器,并且从Web访问数据库时我开始出错.

我可以毫无问题地使用createsuperuser,它创建了我的超级用户.但是,当我尝试使用它登录我的网站时,我得到了错误.

File "/usr/lib64/python3.4/site-packages/django/db/models/sql/compiler.py",    line 1239, in cursor_iter

for rows in iter((lambda: cursor.fetchmany(GET_ITERATOR_CHUNK_SIZE)),
File "/usr/lib64/python3.4/site-packages/django/db/utils.py", line 102, in  inner

File "/usr/lib64/python3.4/site-packages/django/db/backends/postgresql/utils.py", line 6, in utc_tzinfo_factory
raise AssertionError("database connection isn't set to UTC")
AssertionError: database connection isn't set to UTC

我一直在看代码,错误来自这段代码.

from django.utils.timezone import utc
def utc_tzinfo_factory(offset):
    if offset != 0:
    raise AssertionError("database connection isn't set to UTC")
return utc

虽然我无法找到偏移量的起始位置,但我无法弄清楚Django如何确定我的偏移量已关闭.

我的postgresql数据库的时区设置为UTC,并验证了django文档中写的所有postgresql参数,我现在已经没想到为什么会这样.

我希望有人可以帮忙吗？

python3.4 -V:Python 3.4.3

psql -V:psql(PostgreSQL)9.2.15

django-admin --version:1.9.2

更新11/8-2016 - 来自DEBUG视图的完整堆栈

我在utc_tzinfo_factory中找到了偏移量的值,它的值为120.虽然我无法解释它是如何或为什么得到这个值.

下面是Django的调试页面中的副本,其中包含完整堆栈和变量的错误.

Answer 1

对于 18/06/2021，这是一个已知问题，它来自psycopg-2 / psycopg2-binary包。幸运的是，他们的 GitHub 页面上已经有一个未解决的问题，所以希望它很快得到修复。

作为临时修复，您可以将版本固定在requirements.txttopsycopg2-binary>=2.8,<2.9或 中psycopg2>=2.8,<2.9，具体取决于您使用的软件包。

感谢@vinkomlacic在评论中提到这一点。

Answer 2

我在正常运行UTC + 2的服务器上也遇到了同样的问题（在我的情况下是Europe / Oslo）。

原来，我服务器（Centos 7）上的系统zoneinfo文件已损坏，这在中很明显pg_timezone_names。

postgres=# select * from pg_timezone_names where name like 'UTC';
 name | abbrev | utc_offset | is_dst
------+--------+------------+--------
 UTC  | CEST   | 02:00:00   | t
(1 row)

运行yum update tzdata更新我的服务器的时区文件并重新启动PostgreSQL服务器后，该问题似乎已解决。

postgres=# select * from pg_timezone_names where name like 'UTC';
 name | abbrev | utc_offset | is_dst
------+--------+------------+--------
 UTC  | UTC    | 00:00:00   | f
(1 row)

我猜想我以前可能cat /usr/share/zoneinfo/Europe/Oslo > /etc/localtime没有先运行即可/etc/localtime更改系统时区，而是用Europe / Oslo的zoneinfo覆盖了UTC的zoneinfo。

Answer 3

如果您使用的是 psycopg2 2.9，请降级到 psycopg2==2.8.6 或 pip3 install psycopg2-binary==2.8.6。此问题是由 psycopg2 版本 2.9 的最新更新引起的。

Answer 4

这是我发现的一个简单的解决方法，可以为我解决这个问题。即设置：

USE_TZ = False

这有助于解决问题。默认情况下，它设置为 True，因此当我在 Heroku 上使用 PostgreSql 时会出现错误。也许 Django 引擎和数据库之间会发生一些同步。
