In order to use get_absolute_url, first of all you need to have named urls.
Lets imagine we have the following named url.
....
url(r'^accounts/(P?<pk>d+)/$',
DetailView.as_view(
template_name='accounts/details.html',
), name='account_details')
....
In order to referece this url in a template you have to alternatives,
actually 3:
1) You can hardcode the url, eg. /accounts/1
2) Do a reverse url lookup, eg. {% url account_details pk=1%}
3) Use the get_absolute_url method on your instance, eg.
account.get_absolute_url
As you can see, using the get_absolute_url makes for a less hardcoded url;
changin parameters in your view wouldn't mean having to go back in your
templates and updating each one of the references to the url.
In order to define a get_absolute_url in your model you need to use the
@permalink decorator.
@models.permalink
def get_absolute_url(self):
return ('account_details', #name of the view you are reversing
(), # a tuple of all the positional parameter your view takes
{'pk':self.id}, # a dict of all the named arguments your view takes
)
