Sometimes it's useful to dispatch to a different view method based on request.method - e.g. when building RESTful APIs where GET, PUT and DELETE all use different code paths. RestView is an extremely simple class-based generic view which (although it's a stretch to even call it that) which provides a simple mechanism for dividing up view logic based on the HTTP method.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 | """
Example usage:
class ArticleView(RestView):
def GET(request, article_id):
return render_to_response("article.html", {
'article': get_object_or_404(Article, pk = article_id),
})
def POST(request, article_id):
# Example logic only; should be using django.forms instead
article = get_object_or_404(Article, pk = article_id)
article.headline = request.POST['new_headline']
article.body = request.POST['new_body']
article.save()
return HttpResponseRedirect(request.path)
Then in your urls.py:
from my_views import ArticleView
urlpatterns = patterns('',
...
(r'^article/(\d+)/$', ArticleView()),
...
)
"""
from django.http import HttpResponse
import re
nonalpha_re = re.compile('[^A-Z]')
class RestView(object):
"""
Subclass this and add GET / POST / etc methods.
"""
allowed_methods = ('GET', 'PUT', 'POST', 'DELETE', 'HEAD', 'OPTIONS')
def __call__(self, request, *args, **kwargs):
method = nonalpha_re.sub('', request.method.upper())
if not method in self.allowed_methods or not hasattr(self, method):
return self.method_not_allowed(method)
return getattr(self, method)(request, *args, **kwargs)
def method_not_allowed(self, method):
response = HttpResponse('Method not allowed: %s' % method)
response.status_code = 405
return response

Hah! I was sure someone else had done this before (it's an obvious approach) but my Google-fu failed me.
