小编Dea*_*oke的帖子

我有一个RadioGroup rg1,我想获得所选单选按钮的值.

我知道我可以使用以下方法获取id所选单选按钮:

if(rg1.getCheckedRadioButtonId()!=-1)
int id= rg1.getCheckedRadioButtonId()

这给了我id,但我想要那个按钮的值.

如果输入包含空格分隔的int行,则 -

1 3

我可以使用该map()函数将其存储在数组中

arr = map(int,sys.stdin.readline().split())

或者甚至在两个单独的变量中

n,m = map(int,sys.stdin.readline().split())

有没有办法使用相同的方法来读取包含混合数据类型的输入行.例如.-

foo 3

where foo是一个字符串,3是一个整数？

我正在尝试将模板文件中的值传递给Django中views.py文件中的函数.

我的项目结构如下 -

myproject/
    manage.py
    myproject/
        __init__.py
        urls.py
        wsgi.py
        views.py
        settings.py
    orders/
        __init__.py
        models.py
        views.py
        urls.py
        tests.py
    restaurant/
        __init__.py
        models.py
        views.py
        urls.py
        tests.py

     requirements.txt

这是我的templates/menu.html档案 -

...
...    
{% for id,image,menu in imageList %}
    <div style = "display:inline-block">
        <img src="{{ MEDIA_URL }}{{ image }}">
        <p>{{ menu }}</p>
        <a href="{% url 'addCart' id %}">+</a>
        <a href="">-</a>
    </div>
{% endfor %}
...
...

的orders/urls.py是-

....
from orders.views import add_to_cart

urlpatterns = patterns('',
    url(r'^add/(?P<product_id>\d+)$', add_to_cart, name ='addCart'),
)

根源 …

安装bootstrap3之后

$ pip install django-bootstrap3

而我virtualenv很活跃.即

(venv)deathstroke@Batcomputer:~/Documents/DjangoProjects/venv/bin$ pip install django-bootstrap3

但是,给出了以下错误 -

Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/home/deathstroke/Documents/DjangoProjects/venv/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 338, in execute_from_command_line
    utility.execute()

    django.setup()

    app_config = AppConfig.create(entry)
  File "/home/deathstroke/Documents/DjangoProjects/venv/local/lib/python2.7/site-packages/django/apps/config.py", line 119, in create
    import_module(entry)
  File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module
    __import__(name)
ImportError: No module named bootstrap3

当我import bootstrap3在shell中运行时,它可以工作.

为什么我的Django应用程序没有找到或识别它？
