Several weeks back I was exposed to Python and Django for the first time, and it really got me thinking. While I'm not a huge fan of Python syntax, I really did like the setup for Django, and how it implements MVC. One of the first things that I loved was this little tid-bit for linking up URL requests to views:
from django.conf.urls.defaults import *
urlpatterns = patterns('',
(r'^polls/$', 'mysite.polls.views.index'),
(r'^polls/(?P<poll_id>\d+)/$', 'mysite.polls.views.detail'),
(r'^polls/(?P<poll_id>\d+)/results/$', 'mysite.polls.views.results'),
(r'^polls/(?P<poll_id>\d+)/vote/$', 'mysite.polls.views.vote'),
)
urlpatterns = patterns('',
(r'^polls/$', 'mysite.polls.views.index'),
(r'^polls/(?P<poll_id>\d+)/$', 'mysite.polls.views.detail'),
(r'^polls/(?P<poll_id>\d+)/results/$', 'mysite.polls.views.results'),
(r'^polls/(?P<poll_id>\d+)/vote/$', 'mysite.polls.views.vote'),
)
In that block, Django is defining regular expressions that map to Python functions, and defining how to pull named variables out of that regular expression, so that if you requested /polls/23/ becomes a call to the mysite.polls.views module to do the following:
# mysite.polls.views is the module, details is the function
detail(request=<HttpRequest object>, poll_id='23')
detail(request=<HttpRequest object>, poll_id='23')
Isn't that cool? I'd love to be able to do that in ColdFusion, but it looks like there are a number of hurtles I have to get past before I can make this work:
- How do I make ColdFusion get the variables out of that URL path?
- How do I make ColdFusion look at a URL that doesn't exist?
