get_absolute_url 带参数

Question

我的urls.py:

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

我的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', ???)

我的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)

是否可以使用 get_absolute_url 查看不同的个人资料？例如，当您在 /admin 中查看个人资料 "John" 时，您单击 "view on site" 并获得带有 john 数据的个人资料页面，而不是您的

Answer 1

您的视图必须能够接受额外的参数，最好是用户 ID，因为名称通常包含空格：

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)

然后你的urls.py变成：

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

最后是您的 models.py 和 get_absolute_url 方法：

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)
