我已经完成了这个，这个并遵循了这个领域的文档，但我仍然收到错误。我不知道如何调试它。最后追溯。

更新：使用 MySQL 后端是罪魁祸首。SQLite3 很好，但是传入 django 后端 MySQL 编译器代码的查询数据什么都不返回，并且当它自己执行时，返回一个错误。其他人有这个问题，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'),

输入一个博客。

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，但还看不到发生了什么。有人有什么想法吗？我正在运行百日草 0.14.1

I have change the timezone of mysql like this

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)

but the error was still existed.

总之，需要手动加载时区信息，问题就解决了。未知时区是问题所在。
