我有一个DetailView,如果当前登录的用户创建了一个userprofile,它将显示userprofile。如果用户没有创建配置文件,我需要一个else条件。由于我是django和python的新手,甚至更新的CBV,我无法弄清楚我的下一步。我希望def get_object()中有一种方法可以重定向到UserProfile。 如果没有userprofile,则会导致Related Object DoesNotExist错误。如何编写else或except条件以重定向到ProfileView(表单以创建配置文件)
PS:UserProfile是创建配置文件,UserProfileView是查看a 创建的配置文件,UserProfileUpdate将更新现有的配置文件。
我不想通过网址传递PK
我是django 2.0,python 3.6.3
专门寻找如何从DetailView方法重定向except / if案例

我知道您的问题已经很老了,但是没有人真正回答过,所以我想我会
我建议在您的用户模型上创建一个方法,以检查是否有用户配置文件,例如:
def has_profile(self):
return hasattr(self, 'userprofile')
'hasattr'将返回True或False。 现在,您可以在分派中完成
def dispatch(self, request, *args, **kwargs):
if not self.request.user.has_profile():
return redirect('users:userprofile')
return super().dispatch(request, *args, **kwargs)

class UserProfileView(DetailView):
model = UserProfile
context_object_name = 'userprofile'
template_name = 'x.html'
def get(self, request, *args, **kwargs):
from django.http import Http404
try:
self.object = self.get_object()
context = self.get_context_data(object=self.object)
return self.render_to_response(context)
except Http404:
# redirect is here
from django.shortcuts import redirect
from django.urls import reverse_lazy
return redirect(reverse('users:userprofile_create'))

所以经过互联网搜索后,这是我能想到的最佳答案。希望其他人会发现这个有用,或者一个知识更丰富的人有更优化的解决方案。
class UserProfileView(DetailView):
model = UserProfile
context_object_name = 'userprofile'
template_name = 'x.html'
def dispatch(self, request, *args, **kwargs):
try:
self.object = self.request.user.userprofile
except:
return redirect('users:userprofile')
self.get_object()
return super(UserProfileView, self).get(request, *args, **kwargs)
def get_object(self):
self.object = self.request.user.userprofile
return self.object
我在这里所做的(或者更确切地说django为我做的)是使用派遣。通过使用dispatch,我只能过滤那些具有配置文件的用户继续获取配置文件或使用get_object方法返回UserProfile对象。如果用户没有配置文件,则dispatch方法中的except条件会将用户重定向到配置文件创建页面。如果用户具有配置文件,则调度调用(覆盖。我不确定使用哪个术语)get_object方法来获取现有对象。总而言之,get_object方法可以仅返回对象作为响应。所以我尝试重定向的尝试(注释的代码部分)无法正常工作,因为django不会允许它。如果我的任何解释是错误的,请指出我的缺点
