Often, blogs will have a page showing all posts on a particular topic. Create a new template, “topic.html”:
{% extends "index.html" %}
{% block title %}ODGB Topic: {{ topic.title }}{% endblock %}
{% block headline %}Dead Guys Topic: {{ topic.title }}{% endblock %}
Create a new function in views.py:
def topicalPosts(request, topicSlug):
topic = get_object_or_404(Topic, slug=topicSlug)
posts = Post.objects.filter(live=True, topics=topic).order_by('-date')
context = {'postings': posts, 'topic': topic}
return render_to_response('topic.html', context)
And add Topic to the list of models being imported:
from Blog.postings.models import Post, Topic
In urls.py, make this view use the URL /topic/slug:
(r'^topic/(.+)$', 'topicalPosts'),
This will send any request for the URL …/postings/topic/slug to the “topicalPosts” function. Go ahead and view it as http://127.0.0.1:8000/postings/topic/slug, replacing “slug” with the slug for one of your topics, such as http://127.0.0.1:8000/postings/topic/war.
