from .models import Post
from django.views.generic import ListView
from taggit.models import Tag

def post_list(request, tag_slug=None):
object_list = Post.published.all()
tag = None 


if tag_slug:
tag = get_object_or_404(Tag, slug=tag_slug)
object_list = object_list.filter(tags__name__in=[tag]) # filter the 
all retrive objects depend on tags

urls.py
 path('', views.post_list, name='post_list'),
 path('tag//',views.post_list, name='post_list_by_tag'),
