Question

I tried to get data from ManyToManyField but found not luck. Will you please help me?
Here is My Song App Models.

  class Artist(models.Model):
    name = models.CharField(max_length=100)
    slug = models.SlugField(unique = True,max_length=100,help_text="Suggested value automatically generated from name. Must be unique.")


  class Album(models.Model):
    name = models.CharField(max_length=100)
    slug = models.SlugField(unique = True,max_length=100,help_text="Suggested value automatically generated from name. Must be unique.")
    path = models.CharField(max_length=100,null=True, blank=True)
    language = models.ForeignKey(Category)
    albumid = models.CharField(max_length=100)


  class Song(models.Model):
    title = models.CharField(max_length=100)
    artist = models.ManyToManyField(Artist)
    music = models.ForeignKey(Music)
    album = models.ForeignKey(Album)

Here is my view. I want to print Artist with titles. Titles are working fine. but not Artist

 def movie_details(request,slug):
    movies = get_object_or_404(Movie,slug=slug)
    # calculating wikipedia directory structer for images
    #image_name = movies.image
    name = movies.title
    album_name = Album.objects.get(name__exact=name)
    album_id = album_name.id
    song_list = Song.objects.filter(album=album_id)
    #image_path = generateWikiImage(image_name)
    #
    return render_to_response('base_movies.html',locals(),
                              context_instance=RequestContext(request)
                              )

I tried in template like this. {{song_list.artist}} and getting message like this <django.db.models.fields.related.ManyRelatedManager object at 0x024CBED0>
thanks

Answer 1

ManyRelatedManager is the object that handles the ManyToMany relation there. To get the list of objects that you’re looking for, you need to use its all() method.

In this case, you’d use {{song_list.artist.all}}, which will give you a QuerySet that you can then iterate over in your template.
