django createview如何获取创建的对象 [英] django createview how to get the object that is created

问题描述

我有两个连接的形式。基本上用户填写第一个表单，然后重定向到第二个表单的数据的第二个值。
E.G.我有一个表单电影（第一个表格），然后我被重定向到添加演员到电影的表单（演员）。

在我的情况下电影= Chiamata和Actor = Offerta（我保留意大利人的名字，我需要：D）

罚款。

这些是我的urls在urls.py

  url（r'^ chiamata / $'，ChiamataCreate.as_view（） name ='chiamata_create'），
 url（r'^ chimamata /（？P< pk> \d +）/ offerta $'，OffertaCreate.as_view（），name ='offerta_create'），
  

我有这个创建视图

 code>类ChiamataCreate（CreateView）：
 template_name ='chiamata_form.html'
 form_class = ChiamataForm 
 success_url = reverse_lazy（'offerta_create'，args =（??，））
  

现在的问题是如何获得由chiamataForm创建的对象的PK。我需要将其添加到offerta_create的url。

解决方案

也许你可以使用 get_success_url ）方法（请参阅参考资料）

在这种情况下，它将像：

pre> def get_success_url（self）：
return reverse（'offerta_create'，args =（self.object.id，））


i've two concatenated form. Basically user fills in the first form and then is redirected to the second one which adds value to the data of the first form. E.G. I've a form Movie (first form) and then i'm redirected to the form (actor) which add the actor to the movie.

in my case the Movie = Chiamata and Actor = Offerta (i keep the italians name for what i need :D)

fine.

those are my urls in the urls.py

url(r'^chiamata/$', ChiamataCreate.as_view(),name='chiamata_create'),
url(r'^chimamata/(?P<pk>\d+)/offerta$', OffertaCreate.as_view(), name='offerta_create'),

i've this create view

class ChiamataCreate(CreateView):
    template_name = 'chiamata_form.html'
    form_class = ChiamataForm
    success_url=reverse_lazy('offerta_create',args=(??,))

now the problem is how i can get the PK of the object created by the chiamataForm. I need that to add it to the the url of offerta_create.

解决方案

maybe you could use get_success_url() method (see reference)

In this case, it'd be something like:

def get_success_url(self):
    return reverse('offerta_create',args=(self.object.id,))
