python(09)实践Django-国际化

Django 支持国际化，多语言，而本项目做国际化完全是因为个人不喜欢在页面上写N多中文的描述。

1. setting配置

MIDDLEWARE_CLASSES = (
    ...
    'django.middleware.locale.LocaleMiddleware',
)
LANGUAGE_CODE = 'en'
TIME_ZONE = 'UTC'
USE_I18N = True
USE_L10N = True
USE_TZ = True
#翻译文件所在目录，需要手工创建
LOCALE_PATHS = (
    os.path.join(BASE_DIR, 'locale'),
)
template中加
  'django.template.context_processors.i18n',

2. 生成需要翻译的文件
   python manage.py makemessages -l zh_hans
   python manage.py makemessages -l zh_hant

3. 编写文件
   locale/zh/LC_MESSAGES/django.po

msgid "Action"
msgstr "动作"

msgid "Execute"
msgstr "执行"

msgid "Update"
msgstr "更新"

msgid "Release"
msgstr "发布"

msgid "Sync"
msgstr "同步"

msgid "build_number"
msgstr "构建号"

4. 编译
   django-admin.py compilemessages

5. 页面上使用

var update_btn = '{% trans "Update" %}'.replace('99991937', cellData);
var sync_btn = '{% trans "Sync" %}'.replace('99991937', cellData);
var del_btn = '{% trans "Delete" %}'.replace('99991937', cellData);
