内联管理员表单中的自定义字段视图

I am using inline model admin and many to many relation. I have two model classes User and Videodata and i linked them with many to many relation. Below is my models

我使用内联模型管理员和许多关系。我有两个模型类User和Videodata，我将它们与多对多的关系联系起来。以下是我的模特

class User(models.Model):
    user_id = models.CharField(max_length=40,unique=True)
    user_name = models.CharField(max_length=40)
    user_email = models.EmailField()
    user_city = models.CharField(max_length=40)
    videos_watched = models.ManyToManyField('VideoData', through='WatchedVideo')
    class Meta:
        ordering = ['user_id']
        verbose_name = 'User MetaData'
        verbose_name_plural = 'Users MetaData'
    def __unicode__(self):
        return self.user_id

class VideoData(models.Model):
    video_id = models.CharField(max_length=40,unique=True)
    video_name = models.CharField(max_length=40) 
    class Meta:
        verbose_name = 'User_Video MetaData'
        verbose_name_plural = 'Users_Video MetaData'
    def __unicode__(self):
        return self.video_id

class WatchedVideo(models.Model):
    user = models.ForeignKey(User, to_field = 'user_id')
    videoData = models.ForeignKey(VideoData, to_field = 'video_id')
    time  = models.PositiveIntegerField(null = True)

In User table i see video data but with video_id but i want video_name to be displayed there. I am attaching a link of current output.

在用户表中，我看到视频数据，但有video_id，但我想在那里显示video_name。我附加了当前输出的链接。

你可以在上面看到视频ID是有，但我想要视频名称。我怎样才能做到这一点？？

Add method __str__ to VideoData:

def __unicode__(self):
    return self.video_id

def __str__(self):
    return self.video_name
