Hello people,
I'm trying to write a short module to enable me to cleanup my urls.py
a bit since I'm anticipating deployment nightmares.
I'm trying to be a bit clever about this. Since my application is only
going to be used internally, and it's not in a publishing environment,
I've decided to go along the route of creating a decorator and url
registry for my application.
There is however a slight problemette.
For some reason, and i've no idea why, even though the views module is
being loaded it's not registering the views
## start code
### settings.py
DEFAULT_VIEW_MODULE = 'views'
ROOT_URLCONF = 'project.UrlRegistry'
### UrlRegistry.py
from django.conf.urls.defaults import patterns
import sys
class UrlRegistryResolver:
def __init__(self):
self._patterns = []
self._load_patterns_from_views()
def _load_patterns_from_views(self):
for app in settings.INSTALLED_APPS:
try:
views = "%s.%s" % (app,settings.DEFAULT_VIEW_MODULE)
module = __import__(views,'','',[''])
except ImportError:
pass
return
def RegisterPattern(self,pattern,**kwargs):
def __decorator(view):
self._patterns += patterns(view.__module__,
(pattern,view.__name__,kwargs))
return view
return __decorator
sys.modules[__name__] = UrlRegistryResolver()
## application/views.py
from project import UrlRegistry
import pprint
pp = pprint.PrettyPrinter(indent=2)
@UrlRegistry.register_pattern(r'^test_noargs/')
def testview1(request):
str = StringIO("Test Worked!<br /><pre>")
pp.pprint(UrlRegistry.urlpatterns,str)
return HttpResponse(str.getvalue())
## end code
If someone could anyone shed some light on why the above code is not
working, it would be worth beer tokens? I'm sure it's i'm doing
something fatally dumb. If so, please point me in the direction of the
corner with the 'Dunce' hat.
Ta, muchly
