在布尔值分配中存储布尔变量 [英] Store boolean variable in url dispatching
本文介绍了在布尔值分配中存储布尔变量的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
以下url定义应通过url中是否存在 results / ：
The following url definition should pass whether results/ is present in the url:
url(r'^(?P<question_id>[0-9]+)/(?P<results>(results/)?)shorten/$', views.shorten, name='shorten')
当前它通过 results / 或无就足够简单了：
Currently it passes results/ or None which is sufficient for a simple:
if results:
pass
但是拥有 True 和 False 。
推荐答案
您可以有两个URL模式并传递结果在kwargs中：
You could have two URL patterns and pass results in the kwargs:
url(r'^(?P<question_id>[0-9]+)/results/shorten/$', views.shorten, {'results': True}, name='shorten'),
url(r'^(?P<question_id>[0-9]+)/shorten/$', views.shorten, {'results': False}, name='shorten'),
如果您不想这样做，那么当前还没有一种简单的方法可以将 results 字符串转换为布尔值。您可以编写一个中间件或装饰器，但这太过分了。
If you don't want to do this, then there isn't currently a simple way to cast the results string to a boolean value. You could write a middleware or decorator, but that would be overkill.
