under apache. How can I debug django-piston application?

I usually debug Piston apps by:

1. Setting my handlers to use Basic Authentication, even if I'm normally using something else.
2. Use curl to make requests
3. Use pdb (or ipdb) to set a breakpoint in my handler if desired.

You can conditionally change to BasicAuthentication like this:

auth = {'authentication': WhateverYouAreUsingForAuthentication(realm="YourSite")}

if getattr(settings, "API_DEBUG", None):
    from piston.authentication import HttpBasicAuthentication
    auth = {'authentication': HttpBasicAuthentication(realm="Spling")}

some_handler = Resource(SomeHandler, **auth)

To pass a username and password using curl, use the -u option:

curl -u username:password http://localhost:8000/api/some/endpoint/

So in your local settings module, just set API_DEBUG=True whenever you want to use basic auth.
