django rest框架如何国际化字段

Question

我遵循了Django文档来设置国际化。

我需要返回的各种选择字段的翻译取决于所要求的语言。

例如，我有以下选择字段；

CHOICE_TYPES = (('short', _('Short Term')),('long', _('Long Term')), ('mixed', _('Mixed')),)

我已经按照文档设置了我的语言环境和.po文件。例如：

msgid "Short Term"
msgstr "단기계약"

我在请求中使用Accept-Language头请求语言。

但Django似乎没有看到现场环境，或者还有另一个步骤我没有为DRF采取行动。

当我使用django-hvad进行模型翻译时，Django确实看到了语言请求，并且它们被正确地返回。

任何帮助都将不胜感激。

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': ['templates'],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [

                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

# replicated locale folder in 3 locations as I thought Django couldn't find it 
LOCALE_PATHS = (
    '../locale',
    '<full_path>locale',
    '<full_path>/<app_name>/locale',
)

models.py

from django.utils.translation import ugettext_lazy as _

CHOICES = (('short', _('Short Term')),('long', _('Long Term')), ('mixed', _('Mixed')),)

# In the relevant model/s
term = models.CharField(max_length=10, choices=CHOICES, default='short')

serializers.py

class SomethingSerializer(TranslatableModelSerializer):
    class Meta:
        depth = 1
        model = Something
        fields = (...., ...., 'term')

在区域设置/ja/LC_MESSAGES中

django.po

msgid ""
msgstr ""
"Project-Id-Version: PACKAGE VERSION\n"
"Report-Msgid-Bugs-To: \n"
"Language: ja\n"
"MIME-Version: 1.0\n"
"Content-Type: text/plain; charset=UTF-8\n"
"Content-Transfer-Encoding: 8bit\n"
"Plural-Forms: nplurals=1; plural=0;\n"
"X-Translated-Using: django-rosetta 0.7.12\n"

#: common/models.py:8
msgid "Short Term"
msgstr "test translation"

最后，我运行了如下命令；

$ ./manage.py makemessages -l ja
processing locale ja
$ ./manage.py compilemessages -l ja
processing file django.po in /<Path>/locale/ja/LC_MESSAGES
processing file django.po in /<Path>/locale/ja/LC_MESSAGES
processing file django.po in /<Path>/<App Name>/locale/ja/LC_MESSAGES

我太愚蠢了。它翻译得很好，只是我没有在序列化程序中正确地调用它。

在我的串行化程序中，我有；

class SomethingSerializer(TranslatableModelSerializer):
    class Meta:
        depth = 1
        model = Something
        fields = (...., ...., 'term')

鉴于我应该请求'term‘的显示名称，如下所示；

class SomethingSerializer(TranslatableModelSerializer):
    term = serializers.SerializerMethodField()
    class Meta:
        depth = 1
        model = Something
        fields = (...., ...., 'term')

  def get_term(self,obj):
    return obj.get_term_display()
