get_absolute_url with parameters

问题

My urls.py:

urlpatterns = [
        ...
        url(r'^profile/$', profile.profile, name='profile'),
]

My model:

class Reg(models.Model):
    name = models.CharField(max_length=32, primary_key=True)
    user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.PROTECT, 
        related_name='%(app_label)s_%(class)s_reg', null=True)
    ...

    def get_absolute_url(self):
        return reverse('core:profile', ???)

My views:

@login_required
def profile(request):
    context_dict = {}
    u = User.objects.get(username=request.user)
    context_dict['user'] = u
    r = reg.Reg.objects.get(user=u)
    context_dict['reg'] = r
    return render(request, 'core/reg.html', context_dict)

Is it possible use get_absolute_url to views different profiles? For example from the /admin when you look the profile "John", you click on the "view on site" and obtain the profile page with john datas, not yours

Your views must be able to accept an extra argument, preferably the user id, since names usually contain spaces:

from django.shortcuts import get_object_or_404

@login_required
def profile(request, user_id):
    context_dict = {}
    u = get_object_or_404(User, pk=user_id)
    context_dict['user'] = u
    r = reg.Reg.objects.get(user=u)
    context_dict['reg'] = r
    return render(request, 'core/reg.html', context_dict)

Then your urls.py becomes:

urlpatterns = [
        ...
        url(r'^profile/(?P<user_id>[0-9]+)/$', profile.profile, name='profile'),
]

And finally your models.py and the get_absolute_url method:

class Reg(models.Model):
    name = models.CharField(max_length=32, primary_key=True)
    user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.PROTECT, 
        related_name='%(app_label)s_%(class)s_reg', null=True)
    ...

    def get_absolute_url(self):
        return reverse('core:profile', user_id=self.id)
