1. 安装gettext

2. 在项目主目录下创建locale文件夹

LOCALE_PATHS = (
    os.path.join(BASE_DIR, 'locale'),
)

3. 生成需要的语言

python manage.py makemessages -l zh_Hans
python manage.py makemessages -l jp

4. 在视图中选择要使用的语言

from django.shortcuts import render
from django.http import HttpResponse
from django.utils.translation import ugettext as _
from django.utils import translation

# Create your views here.

def about_us(request):
    language = request.GET.get('language', 'en')
    translation.activate(language)

    output = _('hello world')
    return HttpResponse(output)


def index(request):
    language = request.GET.get('language', 'en')
    translation.activate(language)
    return render(request, 'index.html', {})

5. 在django.mo文件中的msgstr ""中添加翻译后的文字

6. 编译

python manage.py compilemessages

7. 在浏览器中访问localhost:8000/index?language=zh_hans
