Question

我有一个错字，但只是在我处理了这段代码之后才弄乱了：

我尝试重定向到另一个表单并使用相对链接，我们最终使用redirect_lazy并在应用程序中使用url.py：url（r'^ step1 / $'，views.step1，name ='步骤1' ），

我们从一种形式重定向到另一种形式，当您的应用拥有自己的网址时，它不会将相对网址重定向到某个表单：它可能会导致重大问题......无论如何，如果有人卡在那里我会分享整个解决方案。

............................................... ......................... 我有一个问题，我认为是来自使用login_required。这说明修复是使用我在重定向中执行的lazy_reverse，这消除了网站广泛崩溃，并在下面显示相同的错误消息。现在它被孤立到了自己的视野。我认为这是渲染，但我不确定该怎么做......任何帮助都会很棒：

                    *makeProfile app:*

views.py

@login_required

def step1(request):

   title =" Step 1 of 4 "

   profile, created = Profile.objects.get_or_create(user=request.user)
   form = step1Form(request.POST or None, instance=profile)

   context ={
     "title":title,
     "form":form

}

   if form.is_valid():
     instance =form.save(commit=False)
     instance.user = request.user


     name = form.cleaned_data.get("name")
     surname = form.cleaned_data.get("surname")
     country = form.cleaned_data.get("country")
     state = form.cleaned_data.get("state")
     city = form.cleaned_data.get("city")
     statusType = form.cleaned_data.get("statusType")


     instance.name = name
     instance.surname = surname
     instance.country = country
     instance.state = state
     instance.city = city
     instance.statusType = statusType

     instance.save()

     return HttpResponseRedirect(reverse_lazy('makeProfile:step2'))

  return render (request, "makeProfile/step1.html", context)

对堆栈溢出有一些答案，但他们在重定向上使用reverse_lazy解决了这个问题，所以不确定我的是什么。

非常感谢你，如果你读完了所有这些。

Answer 1

我认为你需要这样做;

urlpatterns = [

   url(r'^step1/$', 'views.step1', name='step1'),
   url(r'^step2/$', 'views.step2', name='step2'),
   url(r'^step3/$', 'views.step3', name='step3'),
   url(r'^step4/$', 'views.step4', name='step4'),

]

Answer 2

您有拼写错误，应该是IS MISSING，而不是urlpatterns。

urlpatters

您不需要在step1视图中使用urlpatters = [ url(r'^$', 'views.step1', name='step1'), url(r'^$', 'views.step2', name='step2'), url(r'^$', 'views.step3', name='step3'), url(r'^$', 'views.step4', name='step4'), ]，因为在加载url配置后，视图中的调用会发生。您可以使用重定向快捷方式进一步简化代码。

reverse_lazy

由于重定向上的login_required而使用reverse_lazy，但问题仍然存在：作为循环导入
