Question

当我尝试创建一个基于类的视图来修改我的模型Destino时出现以下错误。如果可能的话，我会在urls.py

中不使用slug或pk

错误：

URLS：

url(r'^modificarVC/modificar.html', modificarVC.as_view(), name='modificarDestino'),

视图：

class modificarVC(UpdateView):
    model = Destino
    template_name = "modificarVC/modificar.html"
    success_url = '/'

    def get_object(self):
        return Destino.objects.get(pk=self.request.GET.get('pk'))

Answer 1

正如一些评论所述，你做了一些与基于类的观点相悖的事情。关于你正在使用的UpdateView，它期望传入一个pk。

# urls.py
url(r'^modificarVC/modificar/(?P<pk>\d+)/$', modificarVC.as_view(), name='modificarDestino')

当您点击/modificarVC/modificar/5/等网址时，UpdateView会自动设置对象，方法是选择模型Destino中ID为5的对象。

# views.py
class modificarVC(UpdateView):
    model = Destino
    template_name = "modificarVC/modificar.html"
    success_url = '/'

Answer 2

您的错误消息提示有问题 - 您的请求网址未包含'pk'请求参数（请参阅“请求网址”）

Destino matching query does not exist.
Request Method: GET
Request URL:    http://localhost:8002/modificarVC/modificar.html

再次运行您的请求，但将pk参数作为查询参数添加到结尾：http://localhost:8002/modificarVC/modificar.html?pk=42

Django 1.7匹配查询不存在
