get_success_url（）只需要3个参数（2） [英] get_success_url() takes exactly 3 arguments (2 given)

问题描述

我正在使用

django-registration-redux（1.4）

< blockjote>

为我的django注册（django 1.8）,,但是，从来没有我注册的网页将显示错误

,,但是在views_valid中的views.py，第43行是编辑功能，似乎没有关于注册表？

views.py

  @login_required 
 def edit_thing（request，slug）：
＃抓取对象... 
 thing = ProductsTbl.objects.get（slug = slug）
如果thing.user！=请求。用户：
 raise Http404 
＃设置我们正在使用的表单... 
 form_class = ProductsTblForm 
如果request.method =='POST'：
＃grab来自提交表单的数据
 form = form_class（d ata = request.POST，files = request.FILES，instance = thing）＃**第43行** 
如果form.is_valid（）：
＃保存新数据
 form.save （）
返回重定向（'thing_detail'，slug = thing.slug）
＃否则只需创建窗体
 else：
 form = form_class（instance = thing）
＃并渲染模板
 return render（request，'things / edit_thing.html'，{
'thing'：thing，
'form'：form，
}） 
 
 
 
 
 
 
 urls.py 
 
  
 
 从django.conf.urls导入模式，url，include 
从django导入admin 
。 view.generic import TemplateView 
从设计器导入视图
 from designer.backends import MyRegistrationView 
 from django.conf import settings 
 from django.contrib.auth.views import（
 password_reset，
 password_reset_done，
 password_reset _confirm，
 password_reset_complete，
）
 
 .... 
 urlpatterns = [
 .... 
 url（r'^ accounts / register / $'，MyRegistrationView.as_view（），name ='registration_register'），
 .... 
] 
  
 
 
 
 
 
 registration_form.html 
 
 
 
 
 
 < h1>注册表单< / h1> 
< form role =formaction =method =post> 
 {％csrf_token％} 
 {{form.as_p}} 
< input type =submitvalue =提交/> 
< / form> 
 {％endblock content％} 
  
 ,,虽然有这个错误，我的数据库仍然写在用户和密码,,,。 
可以任何人告诉我为什么我有这个错误，非常感谢你
 
 
 backends.py 
 
 
 
 
 
  from registration.backends.simple.views import RegistrationView 
 
 class MyRegistrationView（RegistrationView） ：
 def get_success_url（self，request，user）：
＃我们要在＃成功注册后重定向到的命名URL 
 return（'home'）
  
 
 
解决方案
   get_success_url  方法不会请求一个论据。删除它。
  class MyRegistrationView（RegistrationView）：
 def get_success_url（self，user）：
＃在＃成功注册后我们要重定向到的命名URL 
 return（'home'）
  
在这种情况下，由于您始终重定向到 home 视图，您可以设置  success_url  代替：
  class MyRegistrationView（RegistrationView）：
 success_url ='home'
  
 
every one ,, I am using

  
django-registration-redux (1.4)
for my django registration(django 1.8),,however ,,when never I registered the web will show the error

,,but the views.py in form_valid, line 43 it is the editing function,,it seems not about the register??

  
views.py


@login_required
def edit_thing(request, slug):
# grab the object...
    thing = ProductsTbl.objects.get(slug=slug)
    if thing.user != request.user:
        raise Http404
# set the form we're using...
    form_class = ProductsTblForm
    if request.method == 'POST':
# grab the data from the submitted form
        form = form_class(data=request.POST,files=request.FILES,instance=thing)#**line 43**
        if form.is_valid():
            # save the new data
            form.save()
            return redirect('thing_detail', slug=thing.slug)
# otherwise just create the form
    else:
        form = form_class(instance=thing)
# and render the template
    return render(request, 'things/edit_thing.html', {
        'thing': thing,
        'form': form,
    })

,,though got this error ,,my databases still wrote in the user and password,,,.
can any one tell me why I got this error,,thank you very much

  
backends.py


from registration.backends.simple.views import RegistrationView

class MyRegistrationView(RegistrationView):
    def get_success_url(self, request, user):
# the named URL that we want to redirect to after # successful registration
        return ('home') 

解决方案
The get_success_url method does not take request as an argument. Remove it.
class MyRegistrationView(RegistrationView):
    def get_success_url(self, user):
        # the named URL that we want to redirect to after # successful registration
        return ('home') 
In this case, since you always redirect to the home view, you could set success_url instead:
class MyRegistrationView(RegistrationView):
    success_url = 'home'
