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久之前或将来。 为此，我使用人性化软件包中的naturaltimetemplatetag。

{{ event.date|naturaltime }}

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

我希望结果以荷兰语显示，因此我更改了settings.py中的语言： LANGUAGE_CODE = 'nl-nl'

这里是问题：当当前时间与模型中设置的日期时间之间的时差大于24小时时，转换仅是部分的。 过去时间的例子：

# 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，'ago'和'from now'部分不会被翻译。

我深入研究了源代码，找到了以下相关信息，但仍然找不到罪魁祸首。 当差异超过1天时，Naturaltime会调用默认的模板标签timesince / timeuntil。 timesince templatetag可以正确翻译，但是当将结果传递回自然时间以添加'ago'和'from now'部分时，此结果完全不会翻译。

NL语言环境.po文件

# line 259-262 and 302-305, seems working
msgid "an hour ago"
msgid_plural "%(count)s hours ago"
msgstr[0] "een uur geleden"
msgstr[1] "%(count)s uur geleden"
...
msgid "an hour from now"
msgid_plural "%(count)s hours from now"
msgstr[0] "over een uur"
msgstr[1] "over %(count)s uur"

# line 253-254 and 310-311, not working
msgid "%(delta)s ago"
msgstr "%(delta)s geleden"
...
msgid "%(delta)s from now"
msgstr "over %(delta)s"

我是在做错什么还是人性化软件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

我不知道问题是什么，但是升级到Django 2.2可以解决问题。
