I have this solution so far:

class MyBasicAuthentication(BasicAuthentication):
    def __init__(self, *args, **kwargs):
        super(MyBasicAuthentication, self).__init__(*args, **kwargs)

    def is_authenticated(self, request, **kwargs):
        from django.contrib.sessions.models import Session
        if 'sessionid' in request.COOKIES:
            s = Session.objects.get(pk=request.COOKIES['sessionid'])
            if '_auth_user_id' in s.get_decoded():
                u = User.objects.get(id=s.get_decoded()['_auth_user_id'])
                request.user = u
                return True
        return super(MyBasicAuthentication, self).is_authenticated(request, **kwargs)

which seems to do what I want. If user is logged on, then session contains _auth_user_id, if not, the key is missing.

Anyone can think of any problems this approach may cause?

You may want to check out this ticket on tastypie’s GitHub:

https://github.com/toastdriven/django-tastypie/issues/197

The author suggests a very clean approach to authenticate the call with both the session and the API key methods.

There goes the snippet:

class ApiKeyPlusWebAuthentication(ApiKeyAuthentication):
def is_authenticated(self, request, **kwargs):
    if request.user.is_authenticated():
        return True

    return super(ApiKeyPlusWebAuthentication, self).is_authenticated(request, **kwargs)

def get_identifier(self, request):
    if request.user.is_authenticated():
        return request.user.username
    else:
        return super(ApiKeyPlusWebAuthentication, self).get_identifier(request)

Once the user is logged in through your API, you have a Django user session. If you want to check if the user is still logged in (on page refresh for example). You can do:

from tastypie.resources import Resource

class LoggedInResource(Resource):
    class Meta:
        pass

    def get_list(self, request, **kwargs):

        from django.http import HttpResponse

        if request.user.is_authenticated():
            return HttpResponse(status=200)
        else:
            return HttpResponse(status=401)

Client check:

$.ajax({
    type: "GET",
    url: '/api/loggedin/',
    success: function(data) {
        // logged in
    },
    error: function() {
        // not logged in
    }
});

Why not just as simple as the following:

class CommAuthentication(BasicAuthentication):
    def __init__(self, *args, **kwargs):
        super(CommAuthentication, self).__init__(*args, **kwargs)

    def is_authenticated(self, request, **kwargs):
        return request.user.is_authenticated()

I just start to learn tastypie. the above code seemed works for me. Any advantage of your solution ?
