问题描述

Django 1.11.5版，

Django version 1.11.5,

views.py

class SignupPage(CreateView):
    form_class = forms.UserSignupForm
    success_url = reverse_lazy('login')
    template_name = 'signup.html'

website / urls.py

website/urls.py

from django.conf.urls import url
from django.contrib.auth import views as auth_views
from django.contrib.auth.views import LoginView,LogoutView
from . import views

app_name = 'website'

urlpatterns = [

    url(r'^login/', auth_views.LoginView.as_view(template_name='signin_2_w.html'), name='login'),
    url(r'^logout/$', auth_views.LogoutView.as_view(), name='logout'),
    url(r'^signup/', views.SignupPage.as_view(), name='sign_up'),

forms.py

class UserSignupForm(UserCreationForm):

    class Meta:
        fields = ('username','email','password1','password2')


        model = get_user_model()

    def __init__(self,*args,**kwargs):
        super().__init__(*args,**kwargs)
        self.fields['username'].label = "Display Name"
        self.fields['email'].label = "Email Address"
        self.fields['password1'].label = "Password"
        self.fields['password2'].label = "Confirm Password"

proj / urls.py

proj/urls.py

urlpatterns = [

    url(r'^admin/', admin.site.urls),
    url(r'^$',views.HomePage.as_view(),name='home'),
    url(r'^website/',include('website.urls',namespace='website')),
    url(r'^website/',include('django.contrib.auth.urls')),
    url(r'^website/',views.StreamyePage.as_view(),name='streamye'),
    url(r'^thanks/$',views.ThanksPage.as_view(),name='thanks'),
    url(r'^congrats/$',views.CongratsPage.as_view(),name='congrats'),
    url(r'^aboutus/$',views.AboutusPage.as_view(),name='about_us'),

HTML

<ul class="nav navbar-nav navbar-right">
            {% if user.is_authenticated %}
            <li><a href="{% url 'logout' %}">Logout</a></li>
            {% else %}
             <li><a href="{% url 'login' %}">Login</a></li>
             <li><a href="{% url 'sign_up' %}">Signup</a></li>
            {% endif %}
          </ul>

在上面的代码中，注册页面向我抛出错误- django.urls.exceptions .NoReverseMatch：找不到'sign_up'的反向符号。'sign_up'不是有效的视图函数或模式名称。

In the above code, the signup page is throwing me a error -- "django.urls.exceptions.NoReverseMatch: Reverse for 'sign_up' not found. 'sign_up' is not a valid view function or pattern name."

请有人帮我解决问题！
预先感谢！

Please someone help me out where im wrong! Thanks in advance!

推荐答案

您必须修复模板中的链接以定位网站网址：

You have to fix the links in the template to target the website urls :

 {% if user.is_authenticated %}
        <li><a href="{% url 'website:logout' %}">Logout</a></li>
        {% else %}
         <li><a href="{% url 'website:login' %}">Login</a></li>
         <li><a href="{% url 'website:sign_up' %}">Signup</a></li>
 {% endif %}
