Zinnia 在后端 MySQL 的 QuerySet.datetimes() 中返回了无效值

Question

我已经在这方面完成了 this, and this and followed the docs，但我仍然遇到错误。我不知道如何调试它。回溯在最后。

更新：使用 MySQL 后端是罪魁祸首。 SQLite3没问题，但是传入django后端的查询数据MySQL编译代码returns什么都没有，自己执行的时候，returns报错。其他人有这个问题吗？是否有解决方法，或者我完全错了？

重现步骤：

使用MySQL作为数据库。

访问以下视图：

from zinnia.views.archives import EntryIndex
url(r'^testing',
        EntryIndex.as_view(),
        name='zinnia_entry_archive_index'),

输入博客。

刷新视图。

繁荣。

Database returned an invalid value in QuerySet.datetimes(). Are time zone definitions for your database and pytz installed?

我已将其追溯到 zinnia.views.archives.EntryIndex.as_view，但还看不出发生了什么。有人有什么想法吗？我是运行百日草 0.14.1

Answer 1

总之，需要手动加载时区信息，问题解决。未知时区是问题所在。

Answer 2

我已经像这样更改了 mysql 的时区

mysql> SET GLOBAL time_zone = '+8:00';
Query OK, 0 rows affected (0.00 sec)

mysql> SET time_zone = '+8:00';
Query OK, 0 rows affected (0.00 sec)

mysql> SELECT @@global.time_zone, @@session.time_zone;
+--------------------+---------------------+
| @@global.time_zone | @@session.time_zone |
+--------------------+---------------------+
| +08:00             | +08:00              |
+--------------------+---------------------+
1 row in set (0.00 sec)

但错误依然存在。
