Re: Problem with get_absolute_url() in admin

[Joakim Hove]

Thank you;

my main problem was with the sites model - and the default value for
SITE_ID == 1. I had no intention of hardcoding the URL.

Re: Problem with get_absolute_url() in admin

[Anthony Anonde]

the example.com is am example django give for Site. Which means there is a 
way for you to manage more than one site at a time, basically using the 
site_id.
To you Questions, i don't understand why you want to hard code your uri 
routing like that when you can easily use the app_name and name convention 
which is more dynamic then hard coding it like that: 
for example at the model Transaction urls.py 
app_name = "trans"
url(r'(?P-/d+)$', views.func, name='account_trans'),

def get_absolute_url(self):
return reverse("trans:account_trans",  kwargs={"pk":self.pk})


and you will be just fine hope this help

It's enabled by default. And from the admin you can edit that hostname and add 
more sites.
Because Django supports multiple sites with a single admin, it generates fully 
qualified URLs for the "view on site" functionality, if django.contrib.sites is 
in INSTALLED_APPS.

OK - so that might be a smoking gun that I have not configured the "sites" 
model correctly? I have so far not really related to the "sites" 
functionality at all.

It is the default hostname for django.contrib.sites[1] with SITE_ID = 1.

Re: Problem with get_absolute_url() in admin

[Joakim Hove]

Thank  you for answering;

but I do not agree fully with your answer:

1. It is the @permalink decorator which is removed from Django 2.x - not
the get_abolute_url() method.
2. I agree using the reverse in the get_absolute_url() is nicer, and I have
also tried that - but the ersults were the same ... ;-(
3. Yes - I should upgrade

 In version 2 of Django that function has been removed.

For v 1.10 here is a link that might help: 
https://docs.djangoproject.com/en/1.10/ref/models/instances/#get-absolute-url

Here is another link that might be of help: 
https://stackoverflow.com/questions/13503645/what-is-permalink-and-get-absolute-url-in-django?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa

Hope this helps.

BTW the first link says V1.10 is obsolete and is no longer supported!!!

Problem with get_absolute_url() in admin

[Joakim Hove]

Hello,

I have a model `Transaction` which can be viewed at the url: 
/transaction/view/$ID/ - if I just enter that url in the browser, or in 
template everything works. But when I have the following get_abolute_url() 
method:

def get_absolute_url(self):
 return "/transaction/view/{}/".format( self.id )

things do not work from the Admin. When I click on the "View on Site" link 
i am redirected to "http://example.com/transaction/view/23635/"; and I get 
an error message about failed XML parsing. I have no clue where the 
"example.com" address comes from - that string is not in my codebase. If I 
hardcode the get_absolute_url to:

def get_absolute_url(self):
 return "http://127.0.0.1:8000/transaction/view{}/".format(self.id)

That works in development, but needless to say that is not a very good 
approach.

I am on Django 1.10


Regard Joakim
