Django Paranoia comes with the same decorators as Django: require_http_methods, require_GET, require_POST, require_safe. Use these the exact same way you would in Django. But instead import them from this library, for example:
from django_paranoia.decorators import require_POST @require_POST def something_sensitive(request, ...): ...
This will return a HTTP 405 Not Allowed response as usual. But it will also send a warning that an attempt to access with something other than a POST was made.
