How can i remove videos from later for individual users? - django

Question

views.py
here in views.py i have tried to make logic for remove any song from watch later but, i am not able to
build logic for it.Basically dont know how to bring watch_id(primary key) of my watch later model.
def deletewatchlater(request):
if request.method=="POSt":
user=request.user
video_id=request.POST['video_id']
# watch_id=request.POST['watch_id']
wat=Watchlater(user=user,video_id=video_id)
wat.delete()
messages.success(request,"Song delete from watch later")
return render(request,'watchlater.html')
def watchlater(request):
if request.method=="POST":
user=request.user
video_id=request.POST['video_id']
watch=Watchlater.objects.filter(user=user)
for i in watch:
if video_id==i.video_id:
messages.success(request,"Song is already added")
break
else:
wl=Watchlater(user=user,video_id=video_id)
wl.save()
messages.success(request,"Song added to watch later")
return redirect(f"/index/subpage/{video_id}")
wl=Watchlater.objects.filter(user=request.user)
ids=[]
for i in wl:
ids.append(i.video_id)
preserved=Case(*[When(pk=pk,then=pos) for pos,pk in enumerate(ids)])
song=Allmusic.objects.filter(sno__in=ids).order_by(preserved)
return render(request,'watchlater.html',{'song':song})
urls.py

OK I changed your models, view and template.
Changes are these
Creating a foreign key(song_id) in Watchlater, History, Likedsongs models with relationship between AllSongs.
In template we pass {{i.sno}} which is equal to song_id in Watchlater, History, Likedsongs models.
In Your view we get this song_id and filter Watchlater model with these fields(song_id and user) and delete.
