Getting this error when submitting the form associated with this view. Not sure what exactly is the problem, considering I have a form with a very similar structure and it works fine.
#views.py
class Facture_Creer(SuccessMessageMixin, CreateView):
model = Facture
template_name = "facturation/nouvelle_facture.html"
form_class= FormulaireFacture
# permet de retourner a l'URL pointant vers le membre modifie
def get_success_url(self):
return reverse_lazy('facture_consulter',kwargs={'pk': self.get_object().id})
class Facture_Update(SuccessMessageMixin, UpdateView):
model = Facture
template_name = "facturation/nouvelle_facture.html"
form_class= FormulaireFacture
success_message = "Facture mise à jour avec succes"
# permet de retourner a l'URL pointant vers le membre modifie
def get_success_url(self):
return reverse_lazy('facture_consulter',kwargs={'pk': self.get_object().id})
#urls.py
urlpatterns = patterns('',
url(r'^$', TemplateView.as_view(template_name="facturation/index.html")),
url(r'^facture/$', FactureView.as_view()),
url(r'^facture/(?P<id>\d+)', FactureView.as_view(), name='facture_consulter'),
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'),

)

pk_url_kwarg. The name of the URLConf keyword argument that contains the primary key. By default, pk_url_kwarg is 'pk' . context_object_name. Designates the name of the variable to use in the context.
You need to pass an object identifier (pk or slug) so your views know which object they're operating on.
Just to take an example from your urls.py:
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'),
See how the second one has (?P<pk>\d+)/? That is passing a pk to the UpdateView so it knows which object to use. Thus if you go to facture/modifier/5/, then the UpdateView will modify object with pk of 5.
If you don't want to pass a pk or slug in your url, you'll need to override the get_object() method and get your object another way. Url here.

As Alex suggests: for default Django behaviour you have to use "pk" in your url pattern.
If you wish to change the object identifier for the primary key "pk" to a different name, you can define pk_url_kwarg. This is available since Django 1.4.

Hey all I used the new path() function and here is my working example that I'm sure will help:
views.py:
from django.views.generic.detail import DetailView
class ContentAmpView(DetailView):
model = Content
template_name = 'content_amp.html' # Defaults to content_detail.html
urls.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'),
]

Also note that in my settings.py, under TEMPLATES, I have 'APP_DIRS': True. More on path here.

Like Robin said, you can use pk_url_kwarg if you want custom pk name.
But as addition, issue Generic detail view must be called with either an object pk or a slug raises also in slug.
So if you want to create custom slug field (no need to use pk or slug name). You can override slug_field and slug_url_kwarg in your DetailView class.
Here is just another example if you want url as Slug Field.
models.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)
views.py
class ListPost(ListView):
model = Post
template_name = 'blog/list.html'
paginate_by = 2
context_object_name = 'posts'
class DetailPost(DetailView):
model = Post
template_name = 'blog/detail.html'
slug_field = 'url'
slug_url_kwarg = 'url'
urls.py
urlpatterns = [
path('', ListPost.as_view()),
path('<slug:url>/', DetailPost.as_view()),
]
