python - 如何从 Django 查询集中检索项目？

Question

我正在尝试在查询集中获取视频元素，但无法检索它。

user_channel = Everything.objects.filter(profile = request.user, playlist = 'Channel')
print user_channel[0] #returns the first result without error   
print user_channel[0]['video'] #returns error

模型.py：

class Everything(models.Model):
    profile = models.ForeignKey(User)
    playlist = models.CharField('Playlist', max_length = 2000, null=True, blank=True)
    platform = models.CharField('Platform', max_length = 2000, null=True, blank=True)
    video = models.CharField('VideoID', max_length = 2000, null=True, blank=True)
    video_title = models.CharField('Title of Video', max_length = 2000, null=True, blank=True)
    def __unicode__(self):
        return u'%s %s %s %s %s' % (self.profile, self.playlist, self.platform, self.video, self.video_title)

Answer 1

试试这个，你会得到基于过滤器的视频列表

user_channel = Everything.objects.filter(profile = request.user, playlist = 'Channel')
video = [x.video for x in user_channel]
print video/print video[0]

Answer 2

user_channel[0]不是字典。采用

user_channel[0].video
