NoReverseMatchエラーログイン

Question

ユーザーがクリックするのログイン "私は彼らがログインとIEにリダイレクトされるようにしたい、www.exampledomain.com/accounts/usernameGoesHere/

後のURLにユーザー名を追加しようとしたときに

EDIT :: 私はそうのような空の文字列を受け入れるように、私のURLの正規表現パターンを変更：

url(r'^$|(?P<username>[0-9a-zA-Z._]+)/$', login_required(views.IndexView.as_view()), name = 'index'), 

今、私は最初のDjangoの管理者バックエンドにログインするたびに、それが必要としてページのレンダリングhttp://localhost:8000/accounts/FlashBanistan/またはhttp://localhost:8000/accounts/ に移動しますが、まったく同じwユーザー名が途中で失われていると私に伝えています。ここで

私のトップレベルのURLです：

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

# Namespace URLs 
app_name = "pto_request" 

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

、ここでは、アカウントのURLです：

from django.conf.urls import url 
from django.contrib.auth.decorators import login_required 
from accounts.views import (login_view, register_view, logout_view) 
from . import views 

app_name = 'accounts' 

urlpatterns = [ 
    # root url will look like www.website.com/accounts/ 

    url(r'^login/$', login_view, name='login'), 
    url(r'^logout/$', logout_view, name='logout'), 
    url(r'^register/$', register_view, name='register'), 
    url(r'^(?P<username>[0-9a-zA-Z._]+)/$', login_required(views.IndexView.as_view()), name = 'index'), 
] 

は、これは私のログイン図である：

def login_view(request): 
    title = "Login" 
    user_form = UserLoginForm(request.POST or None) 
    if user_form.is_valid(): 
     username = user_form.cleaned_data.get('username') 
     password = user_form.cleaned_data.get('password') 
     user = authenticate(username=username, password=password) 
     login(request, user) 
     return redirect(reverse('accounts:index', args=[username])) 
    return render(request, 'form.html', {'user_form':user_form, 'title':title}) 

これは私のログインですフォーム：

class UserLoginForm(forms.Form): 
    # Define form fields to include. 
    username = forms.CharField() 
    password = forms.CharField(widget=forms.PasswordInput) 
    # Check if user exists and logs in. 
    def clean(self, *args, **kwargs): 
     username = self.cleaned_data.get('username') 
     password = self.cleaned_data.get('password') 
     if username and password: 
      user = authenticate(username=username, password=password) 
      if not user: 
       raise forms.ValidationError('Username or password is incorrect.') 

     return super(UserLoginForm, self).clean(*args, **kwargs) 

、最終的にはこれは私が受けていますエラーのトレースバックログです：

urlpatterns = [ 
    url(r'^admin/', admin.site.urls), 
    url(r'^accounts/', include('accounts.urls', namaspace="accounts")),
