Adding django-reroute to your project

django-reroute is a drop-in replacement for django.conf.urls.defaults:

# Replace
from django.conf.urls.defaults *

# with
from reroute import *

Although it’s better to be explicit:

# Replace
from django.conf.urls.defaults import handler404, handler500, patterns, url, include

# with
from reroute import handler404, handler500, patterns, url, include

HTTP verb dispatching

verb_url patterns can match HTTP verbs in addition to regexes:

from reroute.verbs import verb_url

urlpatterns = patterns('myapp.views',
    url('^regular$', 'regular_old_view'),
    verb_url('GET', '^restful$', 'restful_view')
)

verb_url pattern regexes can be overloaded, enabling routing solely based on HTTP verb:

urlpatterns = patterns('myapp.views',
    verb_url('GET', '^restful$', 'restful_view'),
    verb_url('PUT', '^restful$', 'another_restful_view')
)

Restful resource example:

paychecks = patterns('myapp.views.employees.paychecks',
    verb_url('GET',     '^paychecks$', 'index_paychecks'),
    verb_url('POST',    '^paychecks$', 'add_paycheck'),
)

urlpatterns = patterns('myapp.views.employees',
    verb_url('GET',     '^employees$', 'index_employees'),
    verb_url('POST',    '^employees$', 'add_employee'),

    verb_url('GET',     '^employees/(?P<employee_id>\d+)$', 'show_employee')
    verb_url('PUT',     '^employees/(?P<employee_id>\d+)$', 'update_employee')
    verb_url('DELETE',  '^employees/(?P<employee_id>\d+)$', 'delete_employee'),

    url('^employees/(?P<employee_id>\d+)/', include(paychecks)),
)

Rerouting through wrappers

You can configure a list of view wrappers for a set of url patterns:

from reroute import reroute_patterns

def params_wrapper(view, request, *args, **kwargs):
    # Provide uniform access of GET, POST or PUT parameters
    # through request.PARAMS

    if request.method == 'POST':
        request.PARAMS = dict(request.POST.iteritems())
    else:
        request.PARAMS = dict(request.GET.iteritems())

    return view(request, *args, **kwargs)

urlpatterns = reroute_patterns([params_wrapper], 'myapp.views',
    verb_url('GET', '^restful$', 'restful_view'),
    verb_url('PUT', '^restful$', 'another_restful_view')
)

A wrapper is any callable that takes the arguments: view, request, *args, **kwargs:

class Wrapper(object):
    def __call__(self, view, request, *args, **kwargs):
        return view(request, *args, **kwargs)

urlpatterns = reroute_patterns([Wrapper()], 'myapp.views',
    verb_url('GET', '^restful$', 'restful_view'),
    verb_url('PUT', '^restful$', 'another_restful_view')
)

And you can even get fancy and create your own drop-in replacement for patterns:

from functools import partial
import logging

def wrapper_one(view, request, *args, **kwargs):
    logging.debug("wrapper one")
    return view(request, *args, **kwargs)

def wrapper_two(view, request, *args, **kwargs):
    logging.debug("wrapper two")
    return view(request, *args, **kwargs)

patterns = partial(reroute_patterns, [wrapper_one, wrapper_two])

urlpatterns = patterns('myapp.views',
    verb_url('GET', '^restful$', 'restful_view'),
    verb_url('PUT', '^restful$', 'another_restful_view')
)
