未找到'list_videos‘在/ NoReverseMatch /list/ Reverse处的视频。“list_videos”不是有效的视图函数或模式名称

Question

嗯，我正在尝试创建一个与YouTube非常相似的播放列表。但是播放列表只能由超级用户从管理面板创建，其他用户只能看到该播放列表和播放列表中的视频。当我认为我做完了，然后突然发生了这个错误。我不知道我在哪里弄错了。请帮我解决这个问题。

视频/models.py

class VideosList(models.Model):

    list_title = models.CharField(max_length=255)
    list_cover = models.ImageField(upload_to='list cover', height_field=None, width_field=None, max_length=None,blank =True)
    create_date = models.DateField(default = timezone.now)

    def __str__(self):
        return self.list_title

class VideosModel(models.Model):

    
    videos_lists = models.ForeignKey(VideosList,on_delete=models.CASCADE) 
    video_title = models.CharField(max_length=250)
    video_url = models.URLField(max_length=1200)
    video_discription = models.TextField()
    create_date = models.DateField(default = timezone.now)


    def __str__(self):
        return self.video_title

        return VideosList.objects.filter(create_date__lte=timezone.now()).order_by('-create_date')

    model = VideosModel

在您视频/videos_list.html更新<a>标记中，

<a href="{% url 'videos:list_videos' all_lists.videos_lists.list_title %}"> {{ all_lists.list_title }}</a>
