Trying to pass the Django TDD. manage.py test all passed, but the tests on treehouse are not passing.

Is there anything I missed in my code? Thank you.

songs/models.py 
from django.db import models


class Song(models.Model):
    title = models.CharField(max_length=255)
    artist = models.CharField(max_length=255) 
    performer = models.ForeignKey('Performer')
    length = models.IntegerField()

    def __str__(self):
        return '{} by {}'.format(self.title, self.artist)

class Performer(models.Model):
    name = models.CharField(max_length=255)

    def __str__(self):
        return self.name
songs/views.py 
from django.shortcuts import render
from django.views import generic

from .models import Song, Performer


class SongListView(generic.ListView):
    model = Song
    context_object_name = 'songs'
    template_name = 'songs/song_list.html'


class PerformerDetailView(generic.DetailView):
    model = Performer
    context_object_name = 'performer'
    template_name = 'songs/performer_detail.html'

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['performer'] = Performer.objects.get(pk=self.kwargs['pk'])
        return context


class SongDetailView(generic.DetailView):
    model = Song
    context_object_name = 'song'
    template_name = 'songs/song_detail.html'

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['song'] = Song.objects.get(pk=self.kwargs['pk'])
        return context
songs/templates/songs/performer_detail.html 
{% extends 'base.html' %}

{% block title %}{{ performer }}{% endblock %}

{% block content %}
<h2>{{ performer }}</h2>
<ul>
    {% for song in performer.song_set.all %}
        <li>{{ song }}</li>
    {% endfor %}

I can't spot anything wrong with your code. I ran into this issue as well but was able to submit the code successfully the third time I tried it. If it's passing the TDD.manage.py tests, I recommend you try reloading the submit page or using a different browser to see if that helps.

Hello Zhengyu.

Are you sure it is passing all the tests in the workspaces? Because I have tested it in workspaces and it does not pass (I simply copied and pasted your code in the right files).

To be precise:

I have run the tests one by one (out commenting the other tests) and: The models look ok, they both pass the test.

The views return errors, so out of 5 tests I got 3 errors...

Really! Would you be able to post the Trace back here?

I did not work in the workspaces. I downloaded the project files and worked on locally. In the meantime, I will to work put it up to the workspaces and try again. Thanks a lot.

Never mind, I probably know what is going on here now. The error might do to the urls.py file. Class views are not supported, because the urls.py is waiting for functional views.
