您需要传递一个对象标识符（pk或slug），以便您的视图知道它们在操作哪个对象

以您的

url.py

为例：

url(r'^facture/ajouter/$', Facture_Creer.as_view(), name='facture_creer'),
url(r'^facture/modifier/(?P<pk>\d+)/$', Facture_Update.as_view(), name='facture_update'),

url（r'^facture/ajour/$，facture\u Creer.as\u view（），name='facture\u Creer'），
url（r“^facture/modifier/（？P\d+）/$”，facture\u Update.as\u view（），name='facture\u Update'），

查看第二个如何具有

（？p\d+）/

？这就是将pk传递给UpdateView，以便它知道要使用哪个对象。因此，如果您转到

facture/modifier/5/

，那么UpdateView将修改pk为5的对象

如果不想在url中传递pk或slug，则需要重写该方法并以另一种方式获取对象。Url。

正如Alex所建议的：对于默认的Django行为，您必须在Url模式中使用“pk”

如果希望将主键“pk”的对象标识符更改为其他名称，可以定义。这是从Django 1.4开始提供的。

更新：在Django 2.0.2中，将其更改为：

url(r'^facture/modifier/<int:pk>/$', Facture_Update.as_view(), name='facture_update'),

url（r'^facture/modifier/$，facture\u Update.as\u view（），name='facture\u Update'），

嘿，我使用了新的

path（）

函数，下面是我的工作示例，我相信这会有所帮助：

views.py：

from django.views.generic.detail import DetailView

class ContentAmpView(DetailView):

    model = Content
    template_name = 'content_amp.html'  # Defaults to content_detail.html

URL.py：

from django.urls import path

from .views import ContentAmpView

# My pk is a string so using a slug converter here intead of int
urlpatterns = [
    path('<slug:pk>/amp', ContentAmpView.as_view(), name='content-amp'),
]

从django.url导入路径
从.views导入ContentAmpView
#我的pk是一个字符串，所以在这里使用段塞转换器intead of int
URL模式=[
路径（'/amp'，ContentAmpView.as_view（），name='content-amp'），
]

如Robin所说，如果您想要自定义pk名称，可以使用pk_url_kwarg

但作为补充，必须使用对象pk或slug中的slug调用问题通用细节视图
因此，如果您想创建自定义slug字段（无需使用pk或slug名称）。您可以在DetailView类中重写slug\u字段
和slug\u url\u kwarg

如果您希望url作为Slug字段，这里只是另一个示例
型号.py
class Post(models.Model):
    title = models.CharField(max_length=255)
    url = models.SlugField()
    body = models.TextField()
    image = models.ImageField(upload_to='blog/', blank=True, null=True)

class ListPost(ListView):
    model = Post

    paginate_by = 2
    context_object_name = 'posts'

class DetailPost(DetailView):
    model = Post
    template_name = 'blog/detail.html'

来自django.contrib导入管理
从django.url导入路径

URL模式=[
路径（'admin/'，admin.site.url），

有道理。问题似乎出在def get_success_url（self）上：返回reverse_lazy（'facture_consulter'，kwargs={'pk'：self.get_object（）.id}）部分。你知道从CreateView中取出保存对象的方法吗？不管怎样，找到了。谢谢你的快速回答
