问题描述

提交与此视图关联的表单时出现此错误。考虑到我有一个结构非常相似的表单，而且工作正常，因此不确定是什么问题。

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'),
    url(r'^membre/ajouter/$', Membre_Creer.as_view(), name='membre_creer'),
    url(r'^membre/modifier/(?P<pk>\d+)/$', Membre_Update.as_view(), name='membre_update'),
    #url(r'membre/(?P<pk>\d+)/supprimer/$', Membre_Supp.as_view(), name='membre_delete')
)

urlpatterns += staticfiles_urlpatterns()

推荐答案

您需要传递对象标识符（pk或slug），以便您的视图知道它们正在操作的对象。

You need to pass an object identifier (pk or slug) so your views know which object they're operating on.

仅需t从您的 urls.py 中举个例子：

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'),

查看第二个如何具有（？P< pk> \d +）/ ？那是将pk传递给UpdateView，以便它知道要使用哪个对象。因此，如果转到 facture / modifier / 5 / ，则UpdateView将修改pk为5的对象。

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.

如果您不想在网址中传递pk或slug，则需要覆盖 get_object 方法并以另一种方式获取对象。网址。

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.
