How to generate urls in django


In Django's template language, you can use {% url [viewname] [args] %} to generate a URL to a specific view with parameters. How can you programatically do the same in Python code?

What I need is to create a list of menu items where each item has name, URL, and an active flag (whether it's the current page or not). This is because it will be a lot cleaner to do this in Python than the template language.


If you need to use something similar to the {% url %} template tag in your code, Django provides the django.core.urlresolvers.reverse(). The reverse function has the following signature:

reverse(viewname, urlconf=None, args=None, kwargs=None)

Be aware that using reverse() requires that your urlconf module is 100% error free and can be processed - iow no ViewDoesNotExist errors or so, or you get the dreaded NoReverseMatch exception (errors in templates usually fail silently resulting in None).

I'm using two different approaches in my The first is the permalink decorator:

from django.db.models import permalink

def get_absolute_url(self): 
    """Construct the absolute URL for this Item."""
    return ('', [str(])
get_absolute_url = permalink(get_absolute_url)

You can also call reverse directly:

from django.core.urlresolvers import reverse

def get_absolute_url(self): 
    """Construct the absolute URL for this Item."""
    return reverse('', None, [str(])
