[Django]-How to return the current page url inside a wagtail app's model.py file

A Page model has a field url_path. You thus can access the page URL with:

class PageUrl(Page):

    def returnPageUrl(self):
        return self.url_path

or you can make use of full_url to obtain the full url (including the hostname, etc.):

class PageUrl(Page):

    def returnPageUrl(self):
        return self.full_url

That being said, since it is already a field, I think there is not much use to define an extra method for this.
