Question

我正在尝试理解，当我使用我创建的用户注册表单时，为什么会出现NoReverseMatch错误：

根据我的情况，我参考了相关文件/信息：

我有主管道网址.py名为神经康复的文件/网址.py在

from django.conf.urls import include, url, patterns
from django.conf import settings
from django.contrib import admin
from .views import home, home_files

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^$', home, name='home'),

    url(r'^', include('userprofiles.urls')),
    #Call the userprofiles/urls.py

    url(r'^(?P<filename>(robots.txt)|(humans.txt))$', home_files, name='home-files'),


]

# Response the media files only in development environment
if settings.DEBUG:
    urlpatterns += patterns('',
        url(r'^media/(?P<path>.*)$','django.views.static.serve',{'document_root': settings.MEDIA_ROOT,}),
)

我有一个名为userprofiles的模块/应用程序，其中有userprofiles/网址.py这种方式的文件：

^{pr2}$

对位于userprofiles中的CBVAccountRegistrationView的urlregister调用/网址.py因此：

from django.shortcuts import render
from django.contrib.auth import login, logout, get_user, authenticate
from django.http import HttpResponse, HttpResponseRedirect
from django.template import RequestContext, loader

# Importing classes for LoginView form
from django.views.generic import FormView, TemplateView, RedirectView
from django.contrib.auth.forms import AuthenticationForm
from django.core.urlresolvers import reverse, reverse_lazy

from .mixins import LoginRequiredMixin
from .forms import  UserCreateForm

class AccountRegistrationView(FormView):
    template_name = 'signup.html'
    form_class = UserCreateForm

    # Is here in the success_url in where I use reverse_lazy and I get
    # the NoReverseMatch
    success_url = reverse_lazy('accounts/profile')
    #success_url = '/accounts/profile'

    # Override the form_valid method
    def form_valid(self, form):
        # get our saved user with form.save()
        saved_user = form.save()
        user = authenticate(username = saved_user.username,
                            password = form.cleaned_data['password1'])

        # Login the user, then we authenticate it
        login(self.request,user)

        # redirect the user to the url home or profile
        # Is here in the self.get_success_url in where I  get
        # the NoReverseMatch
        return HttpResponseRedirect(self.get_success_url())

我在其中制作注册表单的表单类UserCreateForm位于userprofiles中/表单.py文件是这样的：

from django import forms
from django.contrib.auth.forms import UserCreationForm, AuthenticationForm
from django.contrib.auth.models import User
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Submit

class UserCreateForm(UserCreationForm):

    def __init__(self, *args, **kwargs):
        super(UserCreateForm, self).__init__(*args, **kwargs)
        self.helper = FormHelper()
        self.helper.add_input(Submit('submit', u'Save'))

    email = forms.EmailField(required=True)

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

    def save(self, commit=True):
        user = super(UserCreateForm, self).save(commit=False)
        user.email = self.cleaned_data['email']

        if commit:
            user.save()
        return user

我的模板是userprofiles/templates/注册.html文件：

{% extends 'base.html' %}
{% load crispy_forms_tags %}
{% block title %}Register{% endblock %}
{% block content %}

<div>
    {% crispy form %}
    {% csrf_token %}

</div>
{% endblock %}

当我转到我的注册用户表单，并按下submitthisavemyuser，我有它的那个尝试重定向到最近创建的用户的配置文件，但我得到了这个错误

我在这件事上可能会发生什么。看来反过来偷懒不管用？在

如有任何帮助，我们将不胜感激：）

Answer 1

reverse_lazy()函数采用view函数或url名称来解析它，而不是url路径。所以你应该叫它

success_url = reverse_lazy('profile/')
#             -^ use url name

但是，我不确定'/'字符在url名称中是否有效。在

如果必须使用path解析到url，请使用^{}函数。在
