django-urlbrevity 0.1.0

为什么要简化字母表？

因为如果你要费心创建短URL，它需要易于阅读和听觉，而不必不断检查你是否读错或听错。

为什么使用Hashids？

因为假设你的模型主键是整数，这是一种在相对较小空间内编码元组的方法。当然，也可以使用 django.utils.http.int_to_base36。

使用方法

在你的settings模块中

INSTALLED_APPS = (
    # ...
    'urlbrevity',
    # ...
)

在你的根urlconf中

from django.conf.urls import patterns, url, include
import urlbrevity

urlpatterns = patterns("",
    # ...
    url(r'redirect/', include(urlbrevity.redirects)),
    # Or if you don't want to redirect ...
    url(r'no_redirect/', include(urlbrevity.no_redirects)),
    # ...
)

在你的模板中

{% load urlbrevity %}
<a href="{% url 'urlbrevity:short' my_model_instance|hashid %}">...</a>
or ...
<a href="{{ my_model_instance|short_url }}">

在你的Python代码中

import urlbrevity
obj = MyModel.objects.get(pk='...')
encoded = urlbrevity.encode_model_instance(obj=obj)
value = encoded.hash
url = reverse('urlbrevity:short', kwargs={'encoded_value': value})
# or ...
url2 = urlbrevity.short_url(obj)

# to re-inflate ...
obj_again = urlbrevity.decode_model_instance(value)

为什么要内部重定向？

因为移动设备是一个重要领域，即使在3G+连接上，重定向也是另一轮往返，可能会失败或变慢。如果可能的话，直接渲染预期输出更容易。
