You are going to have to write your own view, for precisely the reasons
you mentioned. However, you don't need to change the Django source.
Since your URL configuration file is processed first, you can override
any of the specific URLs that might otherwise be dispatched to the
comments' views and send them to your own view functions instead. So,
for example, you might currently have a line like
(r'comments/', include('django.contrib.comments.urls'))
in your urls.py. That list of url patterns is processed from front to
back and the first match is used, so you could divert the posting view
by including a line immediately prior to the above:
(r'comments/post/$', 'myapp.views.json.comment_post'),
(r'comments/', include('django.contrib.comments.urls')),
and so forth.
Overriding the standard URL paths like this is a good way to customise
certain paths.
