Issues with URL conf in Django

So I'm working on a project that displays titles of and songs and albums released by a particular artiste from a database. I'm kinda stuck. I'm trying to create a page that displays the songs in an album when you click on the album link. When the link is clicked, I want the URL to display the name of the artiste and the title of the album but i keep getting served with the same error. It is matching the name of the album with artiste names.

How do I make the page display the songs in the album.

Here's the codes for views

 def home(request):
    artistes = Artiste.objects.all()
    return render(request, 'music/home.html', locals())


 def details(request, artiste):
    artistes = get_object_or_404(Artiste, name=artiste)
    album = Artiste.objects.get(name=artiste).album_set.all()
    single = Artiste.objects.get(name=artiste).song_set.filter(single=True)
    return render(request, 'music/details.html', {'artistes': artistes, 'single': single, 'album':album})


def album_details(request,name,album):
    albums = get_object_or_404(Album, title=album)
    artistes = get_object_or_404(Artiste, name=name)
    single = Album.objects.get(title=album).song_set.filter(single=False)
     return render(request, 'music/album_detail.html', {'albums': albums, 'single': single})

url patterns

app_name = 'music'

urlpatterns = [
    url(r'^$', views.home, name='home'),
    url(r'^(?P<artiste>.+)/$', views.details, name='details'),
    url(r'^(?P<name>.+)/(?P<album>.+)/$', views.album_details, name='album_details')
]

album details page

<body>
    {% if artistes.album_set.all %}
        {% for songs in album %}
            <h4>Albums</h4>
            <!--<img src="{{album.art}}"><br>
            -->
            <a href="{% url 'music:album_details' songs.artiste songs.title %}">{{songs.title}}</a>
            <h5>{{songs.artiste}}</h5>
            <h5>{{songs.title}}</h5>
        {% endfor %}
    {% else %}
         <h3>No albums available</h3>
         <h5>Check Out Songs </h5>
        <ul>
        {% for song in artistes.song_set.all %}
            <li>{{song}} - mp3</li>
        {% endfor %}
         </ul>
    {% endif %}


</body>
</html>

Solution

Your URLs are too generic. .+ matches everything, including things like "Wizked/Starboy" which you intended to be caught by the album_details URL.

You can fix this by switching the order of those URL patterns, but you should also make them less generic - eg r'^(?P<artiste>\w+) etc.
