Django view initialization ordering issues

mixins.py

class BaseViewMixin(object):

    def dispatch(self, request, *args, **kwargs):
        # Set earlier to let get_loggedin_user() and get_context_user() work.
        # They run before the get() and post() methods are called.
        self.request = request
        self.args = args
        self.kwargs = kwargs

        # Run checks before entering the view.
        # Note that is_authorized() does not have access to self.object yet,
        # as the normal get() and post() methods are not entered.
        if not self.is_authorized():
            html = render_to_string("403.html", {}, context_instance=RequestContext(request))
            return HttpResponseForbidden(html)

        # Give all subclasses a chance to fetch database values that depend on the context user,
        # before entering the global get/post code that does everything. In contrast to overriding get/post, the init()
        # function can call super() first, to let the parent class initialize, and then initialize itself.
        # A get/post function can't run super first, since that would execute the whole view.
        self.init()

        # Run the complete request, returning a response
        return super(PermissionMixin, self).dispatch(request, *args, **kwargs)

    def init(self):
        # Hook to override in subclasses
