Hello -
I'm playing around with a blog application and I want it to have a
tagging feature. I have the usual ManyToMany relationship set up with
Post and Tag (I'm not going to past my model since I think everyone is
familiar with this kind of setup).
I have three Posts tagged as follows:
Post1: articles, python, django
Post2: articles, python
Post3: articles, music
Essentially, I would like to be able to go to a URL like:
http://blog/tag/articles/python/django
And get Post1 as a result.
Likewise, I'd like to go to:
http://blog/tag/articles/python
And get Post1 and Post3 as a result.
I have a URL entry set up as follows:
(r'^blog/tag/(.*)', 'ssrc.blog.views.tags'),
I have my tags view set up like so:
def tags(request, url=""):
if url:
posts = {}
for post in Post.objects.all():
for tag in [part for part in url.split("/") if part != ""]:
try:
post.tags.get(name__exact=tag)
posts[post.id] = post
except:
posts[post.id] = None
results = [post for post in posts.values() if post != None]
if len(results) == 0:
raise Http404
else:
return render_to_response("blog/tags.html", {
'posts': results,
})
This works. My question is just if there's a better way to accomplish
this. I realize that it'd be a lot cleaner if I just used hierarchical
categories. However, I'd like to keep this as flexible as possible by
using simple tags.
I apologize if this might have been covered elsewhere -- I did my best
to search the site and archives ahead of time, but I could have missed
something.
Thanks!
-Joe
