NoReverseMatch at / Reverse for 'password_chan

问题:

my views part:

@login_required
def password_change(request, 
        template_name='register.html',
        password_change_form=PasswordChangeForm,):
    if post_change_redirect is None:
        post_change_redirect = reverse('student:login')
    else:
        post_change_redirect = reverse_url(post_change_redirect)
    if request.method == 'POST':
        form = password_change_form(user=request.user, data=request.POST)
        if form.is_valid():
            form.save()
            update_session_auth_hash(request, form.user)
            return HttpResponseRedirect(post_change_redirect)
    else:
        form = password_change_form(user=request.user)
    context = {
        'form': form,
        'title': _('Password change'),
    }   
    return TemplateResponse(request, template_name, context)

@login_required
def password_change_done(request, 
    template_name='password_change_done.html',):

    context = {
        'title': _('Password change successful'),
    }
    return TemplateResponse(request, template_name, context)

my project urls:

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r'^stu/', include('student.urls', namespace='student')),
    url(r'^admin/', include(admin.site.urls)),
]

corresponding app urls:

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

urlpatterns = [
    url(r'^register/$', views.register, name='register'),
    url(r'^login/$', views.user_login, name='login'),
    url(r'^logout/$', views.user_logout, name='logout'),

    url(r'^restricted/', views.restricted, name='restricted'),
    url(r'^mains/', views.mains, name = 'mains'),
]

I'm following django-auth docs. I'm trying to implement them in my own app. Everything works fine. I've made my own login and logout views. But when I add 'password_change' and 'password_change_done' views it throws above exception.

I think that 'password_change_done' view didn't be able to resolve url as I've using 'namespacing' in my project level url's. How can I enforce it to use my namespacing i.e, 'student'?

Please! help me to make it correct....

Thanks! in Advance...

You should be able to use the current_app parameter to tell the URL resolver where your views are.

url(r'^change-password/$', auth_views.password_change, {'current_app': 'student'}, name='password_reset'),
url(r'^password-change-done/$', views.password_change_done,  {'current_app': 'student'}, name='password_change_done'),
