Working with pk arguments within an included URL

[GavinB841]

Hi,

To briefly explained:

• I have a main site which provides links to multiple sports club pages.
• Currently once clicked it opens the club home page and displays information based on that club by passing in the pk.
• I then have many other pages associated to the clubs. e.g. Teams, Player Registration, Shop etc.
• But when I click on the navbar for example "Player Registration" I have no idea how to continue the URL with the originally selected PK and how to use that PK in the view.

***Current I have these pages working off the authenticated user but realistically I want it working off the originally selected club***

I am not sure how to write the view to allow for this to work and then pass the pk argument into the nav bar url simiarlary how I did it on the main site:

<a href="{% url 'clubs:club_home_with_pk' pk=club.pk %}">

Would really appreciate any help been stuck on this for a few months now. 

Below is an example of the Clubs Teams I need this to work for:

Urls.py:

urlpatterns = [
    path('', views.club_home, name='club_home'),
    path('<int:pk>/', include([
        path('home/', views.club_home, name='club_home_with_pk'),
        path('teams/', views.TeamInfo.as_view(), name='teams'),
    ])),

Nav bar for club pages:

<li><a class="nav-link" href="{% url 'clubs:club_home' %}">Home</a></li>
<li><a class="nav-link" href="{% url 'clubs:teams' %}">Team</a></li>
<li><a class="nav-link" href="{% url 'clubs:pitches' %}">Pitches</a></li>
<li><a class="nav-link" href="{% url 'clubs:memberships' %}">Memberships</a></li>

Views.py

def club_home(request, pk=None):
    if pk:
        club = ClubInfo.objects.filter(pk=pk)
        club_posts = ClubPosts.objects.filter(club_id=club[0])
    elif request.user.is_authenticated:
        club = ClubInfo.objects.filter(user=request.user)
        club_posts = ClubPosts.objects.filter(club_id=club[0])
    # photo = model.club_logo.ImageField(storage=profile_pics)
    args = {'club': club,
            'club_posts': club_posts
            }
    return render(request, 'club_home_page.html', args)


class TeamInfo(APIView):
    renderer_classes = [TemplateHTMLRenderer]
    template_name = 'teams.html'

    def get(self, request):
        form = TeamForm()
        user = ClubInfo.objects.filter(user=request.user).first()
        teams = Team.objects.filter(club_id=user.pk)
        return Response({'form': form,
                         'teams': teams,
                         })

    def post(self, request):
        form = TeamForm(data=request.data)
        user = ClubInfo.objects.filter(user=request.user).first()
        teams = Team.objects.filter(club_id=user.pk)
        if form.is_valid():
            form.save()
            return Response({'form': form,
                             'teams': teams
                             })

I think I had a similar scenario a few weeks ago. One option that you have is to store the originally selected PK to the session object. Whenever you load a page, for you can retrieve the PK from the session object. Most likely you'll do this on the get_queryset function

Hi Simon, 

That’s a great idea, I’ve only ever worked with built in sessions for logging in. Would you have a link to some documentation or an example that would help me as I’m relatively new to Django and this has been holding me back months now. 

Thanks

Gavin

Hi Gavin,

Please see this one. https://docs.djangoproject.com/en/2.1/topics/http/sessions/. It first needs to be setup in your settings.py. 

Basically, this is just a field in the database that gets retrieved whenever you want.

# set a session variable

self.request.session['key'] = 'value'

# get a session variable

self.request.session.get('key', None)
