NoReverseMatch at /videos/list/ Reverse for 'list_videos'找不到。 'list_videos'不是有效的视图函数或模式名称

Question

我正在尝试创建一个与YouTube非常相似的播放列表。但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。当我以为我已经完成时，这个错误突然发生了。我不知道我在哪里犯错误。请帮我解决这个问题。

视频/模型.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 

视频/视图.py

class VideosListView(ListView):
model = VideosList
context_object_name = 'videos_lists'  
template_name = "videos/videos_lists.html"
def get_queryset(self):
return VideosList.objects.filter(create_date__lte=timezone.now()).order_by('-create_date')


class VideosModelListView(ListView):
model = VideosModel
template_name = "videos/list_videos.html"
context_object_name = 'videos_list'  
def get_queryset(self,*args, **kwargs):
videoslist = get_object_or_404(VideosList, list_title=self.kwargs.get('list_title'))
return VideosModel.objects.filter(videos_lists=videoslist).order_by('-create_date')

videos/urls.py

app_name = 'videos'
urlpatterns = [
path('list/',views.VideosListView.as_view(),name ='videos_playlist'),
path('list/<str:list_title>/',views.VideosModelListView.as_view(),name ='list_videos'),
]

在您的视频/videos_list.html中，像这样更新<a>标签，

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