小编rya*_*yan的帖子

我试图建立一个朋友供稿，其中列出了我目前与之成为朋友的所有“节拍”对象。如何在我的视图集中访问用户以返回正确的对象？

楷模：

class Beat(models.Model):
    created_at = models.DateTimeField( default=datetime.now)
    title = models.CharField(max_length=255)
    description = models.TextField(blank=True, null=True)
    likes = models.IntegerField(default=0)
    artist = models.ForeignKey(UserProfile, null=True, blank=True)
    audio = models.FileField(upload_to="media_files/audio/",null=True, blank=True)
    beat_cover = models.ImageField(upload_to="media_files/img/",null=True, blank=True);
    admin_name = models.CharField(max_length=255, blank=True, null=True)

    class Meta:
        ordering = ['-created_at']

     def __unicode__(self):
        return unicode(self.admin_name)



class UserProfile(models.Model):
    user = models.OneToOneField(User, blank=True, null=True)
    admin_name = models.CharField(default="beat",max_length=255,blank=True, null=True)
    profile_pic = models.ImageField(upload_to="media_files/users/")

    def __unicode__(self):
        return unicode(self.admin_name)

序列化器：

class AllBeatStreamSerializer(serializers.ModelSerializer):

    class Meta:
        model = Beat
        fields = ('created_at', 'title', 'audio', 'artist' )
        depth = …
