I have a model like this:
from wagtail.wagtailcore.models import Page
class Blog(Page):
created = models.DateTimeField(auto_now_add=True)
...
..
Right Now, my default, if my slug is hi-there, the blog post is accessible on site_url:/hi-there/ but I want it accessible via site:url/2014/02/05/hi-there/ The page has various methods like url, url_path which one should I override and what's the best practice to achieve something like this in wagtail?
