I am currently trying to implement a tag system into my Django project. I am trying to add the tags within each post, and have a category on the right hand side that displays maybe 10-20 of the tags. I am trying to implement this into the feed view, but i am unsure of how to call the slug for each tag in order to do /posts/tag/feed. So once you click on a tag it will redirect to the slug of the tag. Which would make the tag clickable. I tried to follow the link below but it only shows how to do it with the class view.

views.py
def post_feed(request):
if not request.user.is_staff or not request.user.is_superuser:
raise Http404
queryset_list = Post.objects.all()
tags = Tag.objects.all()
query = request.GET.get("q")
if query:
queryset_list = queryset_list.filter(
Q(title__icontains=query)|
Q(tags__icontains=query)|
Q(description__icontains=query)|
Q(user__first_name__icontains=query)|
Q(user__last_name__icontains=query)
).distinct()
paginator = Paginator(queryset_list, 5)
page_request_var = "page"
page = request.GET.get(page_request_var)
try:
queryset = paginator.page(page)
except PageNotAnInteger:
# If page is not an integer, deliver first page.
queryset = paginator.page(1)
except EmptyPage:
# If page is out of range (e.g. 9999), deliver last page of results.
queryset = paginator.page(paginator.num_pages)
context = {
"object_list": queryset,
"title": "List",
"page_request_var": page_request_var,
}
return render(request, "post_feed.html", context)
And here is my url
url(r'^tag/(?P<slug>[-\w]+)/$', post_feed, name='tagged'),
the Tag.objects.all() only pulls up the tags but doesnt request the slugs.
I am unsure of how to add this to my view without changing it.
from django.views.generic import DetailView, ListView
from taggit.models import Tag
from .models import Product
taggit view to add url and query slug:
class TagMixin(object):
def get_context_data(self, kwargs):
context = super(TagMixin, self).get_context_data(kwargs)
context['tags'] = Tag.objects.all()
return context
class ProductDetail(DetailView):
template_name = 'product/detail.html'
context_object_name = 'product'
model = Product
class ProductIndex(TagMixin, ListView):
template_name = 'product/index.html'
model = Product
paginate_by = '10'
queryset = Product.objects.all()
context_object_name = 'products'
class TagIndexView(TagMixin, ListView):
template_name = 'product/index.html'
model = Product
paginate_by = '10'
context_object_name = 'products'
def get_queryset(self):
return Product.objects.filter(tags__slug=self.kwargs.get('slug'))
I have been stuck on this a few days. Any advice would be helpful.
Here is my models.py, sorry had to format it this way to show up as the whole models code.
