Django how to define common url

I am implementing a directory service and as you know listing URLs appear on a lot of places. I am aware of using the {% url %} tag, it's still not bullet proof for cases like global listing url structure changes, say I had {% url id=listing.id %} and had to add slug to the URL like {% url id=listing.id slug=listing.slug %}

While global search & replace is an option, however I am curious if there is a canonical way to approach this issue.

Currently my approach is have a listingurl.html which only has {% url id=listing.id slug=listing.slug %} and wherever needs to have the url will just include listingurl.html, however I am not sure if implementing a custom filter would be more efficient?

The best way to handle it IMHO is to add a get_absolute_url method to your model. Then, instead of working about reversing the URL in the template, you can just call that method:

@models.permalink
def get_absolute_url(self):
    return ('listing_view_name', {'id': self.id, 'slug': self.slug})

Then:

<a href="{{ listing.get_absolute_url }}">{{ listing }}</a>

Not 100% sure this works and if it is the most elegant solution:

some_template.html

{% include 'listing.html' with url_thing %}

listing.html

{% url url_thing id=object.id %}
