Well, you could minimize the amount of code you will have to repeat
for each and every view function by doing some OOP. For instance you
could probably do something like this in your views.py:
class AbstractView(object):
def __init__(self, request, *args, **kwargs):
# Do some generic stuff here
pass
def __call__(self, *args, **kwargs):
raise RuntimeError, "Not implemented"
class TestView(AbstractView):
def __call__(self, *args, **kwargs):
return render_to_response('some_template.html',{})
def create_view(klass):
def _func(request, *args, **kwargs):
return klass(request, *args, **kwargs)()
return _func
test = create_view(TestView)
This module provides the view "test".
In this case, you'd put the whole generic stuff you want _all_ your
views to perform into the __init__ method of the AbstractView class.
This is just a quick solution, but it should give you an idea of how
to share processing between views if the short processing requires
request-specific data.
I hope this helps (and isn't a really stupid solution for your problem ;-) )
