python - Django 1.9.1 NoReverseMatch when using django.auth -


i'm trying learn django following book "django example" , due conflicting versions i'm running problem when trying use django.auth url settings in settings.py. im getting totally frustrated since have no idea how begin debugging error. or advice appreciated here's relevant part of settings.py file

from django.core.urlresolvers import reverse_lazy login_redirect_url = reverse_lazy('dashboard') login_url = reverse_lazy('login') logout_url = reverse_lazy('logout')

app views.py:

from django.shortcuts import render, redirect django.shortcuts import httpresponse django.contrib.auth import authenticate, login, logout .forms import loginform django.contrib.auth.decorators import login_required # create views here. @login_required def dashboard(request):     return render(request, 'account/dashboard.html', {'section': 'dashboard'})

urls.py

from django.conf.urls import url . import views  app_name = 'account' urlpatterns = {     url(r'^$', views.dashboard, name='dashboard'),     url(r'^login/$', 'django.contrib.auth.views.login', name='login'),     url(r'^logout/$', 'django.contrib.auth.views.logout', name='logout'),     url(r'^logout-then-login/$', 'django.contrib.auth.views.logout_then_login', name='logout_then_login'), }

main urls.py :

from django.conf.urls import url, include django.contrib import admin  urlpatterns = [     url(r'^admin/', admin.site.urls),     url(r'^account/', include('account.urls')),  ]

error message

updated settings.py :

login_redirect_url = reverse_lazy('account:dashboard') login_url = reverse_lazy('account:login') logout_url = reverse_lazy('account:logout')

when use app_name sets namespace used when include() urls.py somewhere else.

so there's no url name "login", instead it's called "account:login", , that's name have pass reverse(). 

login_redirect_url = reverse_lazy('account:dashboard') login_url = reverse_lazy('account:login') logout_url = reverse_lazy('account:logout')

relevant docs: url namespaces , included urlconfs

if using django-extensions (you should), can use management command show_urls nicely formatted list of url routes registered in project.

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
