You’ll want to use card.get_absolute_url. See https://docs.djangoproject.com/en/2.0/ref/models/instances/#get-absolute-url In your get_absolute_url, you should probably use the reverse method to use the name of a URL rather than hard-coding it in the method. That’s the second example in that section.
From: django-users@googlegroups.com [mailto:django-users@googlegroups.com] On Behalf Of Lylio Sent: Wednesday, February 14, 2018 9:15 AM To: Django users Subject: Re: Basic note/trello app - how to link model object IDs Thanks for the reply Gonzalo, I really appreciate the feedback. So, conceptually I understand how the remaining pieces of this app fit together - but could I ask for just a little more of your help as I'm struggling with coding the details of what's needed. Let's start basic - I've got some 'cards' in my database and on one of the web pages the title of the card is presented in a list (with some CSS styling to present the list item as a rectangle): <ul> {% for card in cards.all %} <li class="card">{{ card.title }} </li> {% endfor %} </ul> I'd like to click on one of the items in the list and open up a new page showing all the database details for that particular list item (title, description, time of creation, etc). Roughly, would I change the list items into links: <ul> {% for card in cards.all %} <li class="card"><a href='card.html/get(this_object_id)>{{ card.title }}</a></li> {% endfor %} </ul> Then there would be a new view defined, something like def card(request): object = get(this_object_id) context = {'cards': object} return render(request, 'scrumbuddy/card.html', context) I know this code is incorrect, but is it roughly how I should proceed? Connecting the list item URL to the card view which I don't really understand how to do.

It isn't necessary, but it is a good idea What you need is to create a view that renders such template. I suggest you write your own view function that does that, but what you'd usually do is just use a generic view and either pass it the template you want to use, or name the template in a way the generic view will find it on its own.

Yes, in general, every Django model instance has an id (unless you specifically tell it not to), and you can use it to create urls for the detail view I mentioned earlier. This is a good start, but you'll later want to add a SlugField to your Card model, and use that instead of the id so urls look nicer. > I'm maybe asking a bit much here - but I'm unsure of how complex these > requirements are.

When in doubt, revisit the Django tutorial.
