如何在Django / Django Rest Framework中使用已选择的主键（pk）继续新视图的URL

Question

From my index view I list the available "clubs" in my database, when a user select a club it re-directs them to the club home page. I have included a player registration page but I have no idea how I can render this page based on what club the user selected previously in the index. So what I would like to do is output the url like so: http://127.0.0.1:8000/account/club_home/3/player_registration/ "3" being the primary key of the selected club.

urls.py:

url(r'^club_home/$', views.club_home, name='club_home'),
url(r'^club_home/(?P<pk>\d+)/$', views.club_home, name='club_home_with_pk'),
url(r'^club_home/player_registration/$', views.RegisterPlayer.as_view(), name='player_register'),

views.py:

class Index(TemplateView):
template_name = 'index.html'

def get(self, request):
    users = User.objects.all()
    clubs = ClubInfo.objects.all()

    args = {'users': users,
            'clubs': clubs}
    return render(request, self.template_name, args)


def club_home(request, pk=None):
if pk:
    club = ClubInfo.objects.filter(pk=pk)
    user = request.user
else:
    club = ClubInfo.objects.filter(user=request.user)
    user = request.user
args = {'club': club,
        'user': user
        }
return render(request, 'club_home_page.html', args)

class RegisterPlayer(APIView):
    renderer_classes = [TemplateHTMLRenderer]
    template_name = 'player_registration.html'

    def get(self, request):
        serializer = PlayerRegistrationSerializer()
        return Response({'serializer': serializer})

   def post(self, request):
        serializer = PlayerRegistrationSerializer(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response({'serializer': serializer})

model:

from django.db import models
from django.contrib.auth.models import User

class ClubInfo(models.Model):

user = models.OneToOneField(User, on_delete=models.CASCADE)
club_name = models.CharField(max_length=50, default='')
club_logo = models.ImageField(upload_to='profile_pics', blank=True)
club_address1 = models.CharField(max_length=30)
club_address2 = models.CharField(max_length=30, default='')
club_address3 = models.CharField(max_length=30, default='')
club_town = models.CharField(max_length=30)
club_county = models.CharField(max_length=30)
club_country = models.CharField(max_length=30)
# slug = models.SlugField(max_length=150, unique=True)

def __str__(self):
    return self.club_name


class PlayerRegistration(models.Model):

club_name = models.ForeignKey(ClubInfo, on_delete=models.CASCADE)
first_name = models.CharField(max_length=20)
last_name = models.CharField(max_length=20)
dob = models.DateField(max_length=8)
email = models.EmailField(max_length=50)
phone = models.CharField(max_length=12)
mobile = models.CharField(max_length=15)
emergency_contact_name = models.CharField(max_length=40)
emergency_contact_mobile = models.CharField(max_length=15)
address1 = models.CharField(max_length=30)
address2 = models.CharField(max_length=30, default='')
address3 = models.CharField(max_length=30, default='')
town = models.CharField(max_length=30)
county = models.CharField(max_length=30)
country = models.CharField(max_length=30)

def __str__(self):
    return "%s %s" % (self.first_name, self.last_name)

serialiser:

 class UserSerializer(serializers.HyperlinkedModelSerializer):
 class Meta:
    model = User
    fields = ('url', 'username', 'email', 'groups')


class PlayerRegistrationSerializer(serializers.ModelSerializer):

class Meta:
    model = PlayerRegistration
    fields = '__all__'
    labels = {
        'dob': ('D.O.B'),
    }
    widgets = {
        'dob': DateInput(attrs={'type': 'date'})
    }

Answer 1

您应该只保留club_home端点URL模式并添加player_registration ，这样您调用的视图（ views.RegisterPlayer ）将收到club_home主键作为参数：

url(r'^club_home/(?P<pk>\d+)/player_registration/$', views.RegisterPlayer.as_view(), name='player_register')

Answer 2

I accomplished this by creating a session key for the primary key. So when the user selects the club a session is created for this pk and i can then use it throughout the project:

# set a session variable
self.request.session['key'] = 'value'

# get a session variable
self.request.session.get('key', None)
