django - 访问模板内的foreignKey

Question

嗯，这很简单。2个具有ManyToMany关系的模型:

class Artist(models.Model):
   name = models.CharField(max_length=100, unique=True)
   slug = models.SlugField(max_length=100, unique=True,
            help_text='Uniq value for artist page URL, created from name')
   birth_name = models.CharField(max_length=100, blank=True)


class Song(models.Model):
   title = models.CharField(max_length=255)  
   slug = models.SlugField(max_length=255, unique=True,
            help_text='Unique value for product page URL, create from name.')
   youtube_link = models.URLField(blank=False)
   artists = models.ManyToManyField(Artist)

我的 View 应该显示最新的 5 首歌曲:

def songs(request, template_name="artists/songs.html"):
   song_list = Song.objects.all().order_by('-created_at')[:5]
   return render_to_response(template_name, locals(),
                          context_instance=RequestContext(request))

问题出在模板中...我想显示艺术家姓名但只是不知道该怎么做，我尝试过:

{% for song in song_list %}
    {{ artists__name }} - {{ song.title }} 
{% endfor %}  

非常感谢任何帮助!

Answer 1

尝试将模板代码更改为:

{% for song in song_list %}
  {% for artist in song.artists.all %}
    {{ artist.name }} - {{ song.title }} 
  {% endfor %}
{% endfor %}
