[英]How to retrieve items from a django queryset?
我正在尝试在queryset中获取视频元素,但是在检索它时遇到了麻烦。
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
Models.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)
试试看,您会获得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]
user_channel[0]
不是字典。 采用
user_channel[0].video
