在 Django 1x 中,我可以在 URL 中使用两个 id 来创建 URL,如下所示:

网址.py

('^profile/(?P<cpk>[0-9]+)/env/(?P<envid>[0-9]+)/$', views.EnvironmentDetailView.as_view(), name='environment'),

HTML 模板

"{% url 'myapp:environment' cpk=environment.client.id envid=environment.id %}"

模型.py

class Environment(models.Model):
    ...
    ...
    def get_absolute_url(self):
            return reverse('myapp:envmanager', args =[self.client.pk])

视图.py

class EnvironmentDetailView(generic.DetailView):
    '''Detail view of environment'''
    model = Environment
    pk_url_kwarg ="envid"
    template_name = 'myapp/environment.html'

但是当我升级到 Django 2.0 时,我尝试了:

网址.py

path('profile/<int:client_id>/env/<int:pk>/', views.EnvironmentDetailView.as_view(), name='environment'),

html模板

"{% url 'myapp:environment' client_id=environment.client.id pk=environment.id %}"

视图.py

class EnvironmentDetailView(generic.DetailView):
    '''Detail view of environment'''
    model = Environment
    pk_url_kwarg ="environment_id"
    template_name = 'myapp/environment.html'

并得到了这个错误

AttributeError: Generic detail view EnvironmentDetailView must be called with either an object pk or a slug.

您如何正确引用具有两个 id 的 URL 链接?
