Python Django Class-based Views Customizing Class-based Views Custom Mixin

Mixins task 4/4 - Task 1 no longer passing

I've gone through the task a few times with different approaches, and cant seem to see what I'm doing wrong. Each individual step seems right. (and tasks 1 to 3 all pass on their own). What am I missing?

from django.contrib.auth.mixins import LoginRequiredMixin, SuccessMessageMixin
from django.core.urlresolvers import reverse_lazy
from django.views import generic

from . import mixins
from . import models

class ArticleList(generic.ListView):
    model = models.Article

class ArticleDetail(generic.DeleteView, generic.DetailView):
    model = models.Article
    template_name = 'articles/article_detail.html'

class ArticleCreate(LoginRequiredMixin, SuccessMessageMixin, generic.CreateView):
    fields = ('title', 'body', 'author', 'published')
    model = models.Article
    success_message = "Article Created!"

class ArticleUpdate(LoginRequiredMixin, SuccessMessageMixin, generic.UpdateView):
    fields = ('title', 'body', 'author', 'published')
    model = models.Article

    def get_success_message(self):
        obj = self.get_object()
        return "{} updated!".format(obj.title)

class ArticleDelete(LoginRequiredMixin, generic.DeleteView):
    model = models.Article
    success_url = reverse_lazy('articles:list')

class ArticleSearch(generic.ListView):
    model = models.Article

    def get_queryset(self):
        qs = super().get_queryset()
        term = self.kwargs.get('term')
        if term:
            return qs.filter(body__icontains=term)
        return qs.none()
from django.contrib import messages

class SuccessMessageMixin:
    success_message = ""

    def get_success_message(self):
        return self.success_message

    def form_valid(self,form):
        formmessage = self.get_success_message()
        return super().form_valid(form)

I re-typed everything, and it passed with no changes. Must have been some hidden characters in "cut-'n-paste"
