and fuction for upload image:

def upload_gallery_image(instance,filename):
return f"images/memory/{instance.memory.memory_title}/gallery/{filename}"

views.py:

class ShowmMemries(View):
def get(self,request,*args, **kwargs):
    memories=Memory.objects.filter(is_active=True)
    if request.user.is_authenticated:
        list_memory_liked=MemoryLike.objects.filter(user_liked_id=request.user.id).values("memory_id")
        list_memory_liked_id=[memory["memory_id"] for memory in list_memory_liked]
        return render(request,'MemoriseFerdowsApp/showmemory.html',context={'memories':memories,'list_memory_liked_id':list_memory_liked_id})
    return render(request,'MemoriseFerdowsApp/showmemory.html',context={'memories':memories})

I may be missing something but it looks like you may just need to make one of your carousel-item's active. From the bootstrap carousel docs:

Initial active element required The .active class needs to be added to one of the slides. Otherwise, the carousel will not be visible.
