get_absolute_url() with multiple args

models.py, urls.py, views.py

I'm trying to set a get_absolute_url() function for the Entry class, but failing. I have successfully created such a function for the Category class, with only one arg, but am stuck on using multiple args as in the Entry class.

Currently, clicking a

<a href="/blog/{{ entry.get_absolute_url }}/">{{ entry.title }}</a>`

link, as appears on my index page, only returns the url below:

http://127.0.0.1:8000/blog//

I originally used returns without reverse like this:

def get_absolute_url(self):
    return "/%s/%s/%s/" % (self.pub_date.year, self.pub_date.month, self.slug)

but, whilst it worked from index.html with the earlier mentioned href, from other pages (i.e. category.html) this returned a URL with this appended upon the current URL, including for the Category class. Switching to reverse fixed this issue for Category, but I couldn't get it to work for Entry, because of the multiple args.

Please request any additional data as is desirable.

Edit: Well, I've managed to make it work with(the original code):

def get_absolute_url(self):
    return "%s/%s/%s/%s" % (self.pub_date.year, self.pub_date.month, self.pub_date.day, self.slug)

by changing the href at category.html to:

<a href="http://127.0.0.1:8000/blog/{{ entry.get_absolute_url }}">{{ entry.title }}</a>

i.e. I added the root http://127.0.0.1:8000, but I still can't get it to work with reverse()... I've tried args, kwargs, some other things... I'm not actually sure still what reverse() does differently though to a regular return. It did something differently, as before when I was using the "blog/{{ category.get_absolute_url }}" without the root, switching from return to return reverse() made it work; although I've now managed to get it to work with just return, by adding the root to the href as I did with Entry.

You can use kwargs with reverse. Something like:

Assuming your url pattern for blog detail is like:

url(r'^blog/(?P<year>)/(?P<month>)/(?P<slug>[-\w]+)/$', 'details', name='blog_details')

You can write get_absolute_url as:

def get_absolute_url(self):
    return reverse('blog_details', kwargs={'year': self.pub_date.year,
                                     'month': self.pub_date.month,
                                     'slug': self.slug})

And use it in template as you are using.
