最近在django项目中使用django-filer管理后台文件，就算我把django的setting中额语言设置成为了LANGUAGE_CODE = 'zh-Hans',页面仍然汉化无效。我在django-filer的依赖安装目录页发现了zh-Hans的翻译包。

根据博客https://*.com/questions/12101811/trans-string-not-working-on-templates-but-trans-variable-does/12223367我找到了django拉取翻译包的代码。

def to_locale(language):
    """Turn a language name (en-us) into a locale name (en_US)."""
    language, _, country = language.lower().partition('-')
    if not country:
        return language
    # A language with > 2 characters after the dash only has its first
    # character after the dash capitalized; e.g. sr-latn becomes sr_Latn.
    # A language with 2 characters after the dash has both characters
    # capitalized; e.g. en-us becomes en_US.
    country, _, tail = country.partition('-')
    country = country.title() if len(country) > 2 else country.upper()
    if tail:
        country += '-' + tail
    return language + '_' + country

　　实际上，LANGUAGE_CODE = 'zh-Hans',拉取的是zh_Hans包里面的翻译内容，但是django-filer的翻译包的中文目录名称是zh-Hans，修改名称后果然解决问题
