Django Issues with Multi Authentication in Tasty Pie SessionAuthentication Not Working

Question

I'm trying to get 'Multi Authentication' to work in Tasty Pie. So far ApiKeyAuthentication() works making external calls, but when I use the API on my own Django site 'SessionAuthentication' (the same site the API is hosted on) it fails the authentication despite the user being logged in.

Have I missed something?

Tasty Pie Doc on Multi Authentication here

My Resource:

class CommonMeta:
    """
    Based Mata to which all other model resources extend/inherit.
    """
    # MultiAuthentication is used here, wraps any number of other authentication classes,
    # attempting each until successfully authenticating.
    authentication = MultiAuthentication(ApiKeyAuthentication(), SessionAuthentication())
    authorization = UserObjectsOnlyAuthorization()



class ContactResource(MultipartResource, ModelResource):
    class Meta(CommonMeta):
        queryset = Contact.objects.all()
        resource_name = 'contacts'
        list_allowed_methods = ['get']
        detail_allowed_methods = ['get', 'put', 'post']
        excludes = ['id']

My AJAX request:

 $.ajax({
          url: '/api/v1/contacts/' + id + "/",
          type: 'PUT',
          data: {"company": "test"},

          // On success.
          success: function(data) {
            alert('Load was performed.');
          }

       });

    };

I think it's working as it should, you may have just missed one important note on Tasty Pie docs

It requires that the user has logged in & has an active session. 
They also must have a valid CSRF token.

You need to pass a valid CSRF token for SessionAuthentication to work.

Here is an example:

First setup a function to send a csrftoken with every ajax request

function csrfSafeMethod(method) {
    // these HTTP methods do not require CSRF protection
    return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
}

Then on your ajax setup:

 $.ajaxSetup({
            crossDomain: false, // obviates need for sameOrigin test
            beforeSend: function(xhr, settings) {
                if (!csrfSafeMethod(settings.type)) {
                    xhr.setRequestHeader("X-CSRFToken", $.cookie('csrftoken'));
                }
            }
        });

Last in your template don't forget to include the {% csrf_token %} tag!
