在Django中使用多语言
配置中间件
MIDDLEWARE = [
......
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.locale.LocaleMiddleware', # 此行重点
'django.middleware.common.CommonMiddleware',
......
]
配置翻译文件目录
- 根目录下创建目录
locale
# 国际化翻译文件目录
LOCALE_PATHS = [
os.path.join(BASE_DIR, 'locale'), # 翻译文件所在目录，请手动创建目录
]
创建语言文件
python manage.py makemessages -l zh_Hans
python manage.py makemessages -l en
如果上述报错：Can’t find msguniq. Make sure you have GNU gettext tools 0.15 or newer installed
则需要安装 gettext，访问https://mlocati.github.io/articles/gettext-iconv-windows.html 下载安装包，一路next即可
在需要翻译的地方使用_函数
# 导入
from django.utils.translation import gettext_lazy as _
_("你好") # 纯字符串
_('Today is %(month)s %(day)s.') % {'month': m, 'day': d} # 携带变量的字符串
把函数标记的字符串，自动加入到翻译文件中
python manag服务器托管网e.py makemessages
文件内容如下

msgid "你好" # 标记的字符串
msgstr "hello" # 对应语言需要显示的字符串
msgid "Today is %(month)s %(day)s." # %(params_name)s 为申明变量
msgstr "今天是%(month)s月%(day)s日"
翻译完后，需要编译翻译文件
python manage.py compilemessages
如果需要动态切换语言，可以使用activate函数
from django.utils.translation import activate
示例
from django.utils.translation import activate, get_language_info
from django.utils.translation import gettext_lazy as _
activate("en")
print(_("你好")) # hello
activate("zh-Hans")
print(_("你好")) # 你好
m = 1
d = 2
print(_('Today is %(month)s %(day)s.') % {'month': m, 'day': d}) # 今天是1月2日
