Django Humanize naturaltime templatetag 仅部分翻译

Question

Django 2.1 版

我有一个显示事件的应用程序。我想显示事件发生在多长时间之前或未来多长时间。为此，我使用了 humanize 包中的 naturaltime 模板标签。

{{ event.date|naturaltime }}

# my model in models.py
class Event(models.model):
    # ... other fields
    date = models.DateTimeField(...)

我希望结果是荷兰语，所以我在 settings.py 中更改了语言：LANGUAGE_CODE = 'nl-nl'

问题来了： 当当前时间与模型中设置的 datetime 时间差大于 24 小时时，只进行部分平移。 过去的例子：

# english
one hour ago
# dutch, correct
een uur geleden

# enlish
6 days, 2 hours ago
# dutch translation, only partial
6 dagen, 2 uur ago

未来时间的例子

# english
2 hours from now
# dutch translation, correct
over 2 uur

# enlish
1 month from now
# dutch translation, only partial
1 maand from now

如您所见，当时差大于 24 小时时，“以前”和“从现在”部分不会被翻译。

我钻研了源码，找到了以下相关信息，但还是找不到罪魁祸首。 Naturaltime调用默认模板标签timesince/timeuntil时差超过1天。 timesince 模板标签翻译正确，但是当结果被传递回 naturaltime 以添加 'ago' 和 'from now' 部分时，这个结果根本不会被翻译。

是我做错了什么还是人性化包或荷兰语翻译文件中的错误？

PS。我没有使用任何自定义翻译文件

我不知道是什么问题，但是升级到 Django 2.2 解决了这个问题。
