get_absolute_url

get_absolute_url(), which returns a URL for displaying individual model records on the website (if you define this method then Django will automatically add a "View on Site" button to the model's record editing screens in the Admin site). A typical pattern for get_absolute_url() is shown below.

def get_absolute_url(self):
    """Returns the url 
    to access a particular instance of the model."""
    
    return reverse('model-detail-view', args=[str(self.id)])

Note: Assuming you will use URLs like /myapplication/mymodelname/2 to display individual records for your model (where "2" is the id for a particular record), you will need to create a URL mapper to pass the response and id to a "model detail view" (which will do the work required to display the record). The reverse() function above is able to "reverse" your url mapper (in the above case named 'model-detail-view') in order to create a URL of the right format.
Of course to make this work you still have to write the URL mapping, view, and template!
