NoReverseMatch at /polls/
'polls' is not a registered namespace とエラーが出ました。
http://localhost:8000/polls/ にアクセスした時にこのエラーが出ました。
base.htmlは
{% load staticfiles %} {% load bootstrap3 %} <html lang="en"> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1"> <!-- The above 3 meta tags *must* come first in the head; any other head content must come *after* these tags --> <meta name="description" content=""> <meta name="author" content=""> <link rel="icon" href="../../favicon.ico"> <title>Starter Template for Bootstrap</title> <!-- Bootstrap core CSS --> <link href="static/css/bootstrap.min.css" rel="stylesheet"> <style type="text/css"> body { padding-top: 50px; } </style> </head> <body> <nav class="navbar navbar-inverse navbar-fixed-top"> <div class="container"> <div class="navbar-header"> <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar"> <span class="sr-only">Toggle navigation</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> <a class="navbar-brand" href="{% url 'index' %}">Tutorial</a> </div> <div id="navbar" class="collapse navbar-collapse"> <ul class="nav navbar-nav"> <li class="{% block nav_polls %}{% endblock %}"><a href="{% url 'polls:index' %}">polls</a></li> <li class=""><a href="{% url 'admin:index' %}">admin</a></li> </ul> </div><!--/.nav-collapse --> </div> </nav> <div class="container"> {% bootstrap_messages messages %} {% block contents %}{% endblock %} </div><!-- /.container --> <!-- Bootstrap core JavaScript ================================================== --> <!-- Placed at the end of the document so the pages load faster --> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script> <script>window.jQuery || document.write('<script src="../../assets/js/vendor/jquery.min.js"><\/script>')</script> <script src="{% static 'js/bootstrap.min.js' %}"></script> </body> </html>
のように書いています。
親アプリのurls.pyに
from django.conf.urls import include,url from django.contrib import admin from polls.views import index urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^polls/',include('polls.urls', namespace="polls")), url(r'^$/',index,name='index'), ]
とnamespace="polls" を追加すると
Traceback (most recent call last): File "/Users/XXX/Desktop/djangostudy/django/django/utils/autoreload.py", line 220, in wrapper fn(*args, **kwargs) File "/Users/XXX/Desktop/djangostudy/django/django/core/management/commands/runserver.py", line 120, in inner_run self.check(display_num_errors=True) File "/Users/XXX/Desktop/djangostudy/django/django/core/management/base.py", line 363, in check include_deployment_checks=include_deployment_checks, File "/Users/XXX/Desktop/djangostudy/django/django/core/management/base.py", line 350, in _run_checks return checks.run_checks(**kwargs) File "/Users/XXX/Desktop/djangostudy/django/django/core/checks/registry.py", line 73, in run_checks new_errors = check(app_configs=app_configs) File "/Users/XXX/Desktop/djangostudy/django/django/core/checks/urls.py", line 40, in check_url_namespaces_unique all_namespaces = _load_all_namespaces(resolver) File "/Users/XXX/Desktop/djangostudy/django/django/core/checks/urls.py", line 57, in _load_all_namespaces url_patterns = getattr(resolver, 'url_patterns', []) File "/Users/XXX/Desktop/djangostudy/django/django/utils/functional.py", line 36, in __get__ res = instance.__dict__[self.name] = self.func(instance) File "/Users/XXX/Desktop/djangostudy/django/django/urls/resolvers.py", line 397, in url_patterns patterns = getattr(self.urlconf_module, "urlpatterns", self.urlconf_module) File "/Users/XXX/Desktop/djangostudy/django/django/utils/functional.py", line 36, in __get__ res = instance.__dict__[self.name] = self.func(instance) File "/Users/XXX/Desktop/djangostudy/django/django/urls/resolvers.py", line 390, in urlconf_module return import_module(self.urlconf_name) File "/Users/XXX/.pyenv/versions/3.5.0/lib/python3.5/importlib/__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 986, in _gcd_import File "<frozen importlib._bootstrap>", line 969, in _find_and_load File "<frozen importlib._bootstrap>", line 958, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 673, in _load_unlocked File "<frozen importlib._bootstrap_external>", line 662, in exec_module File "<frozen importlib._bootstrap>", line 222, in _call_with_frames_removed File "/Users/XXX/Desktop/djangostudy/djangostudy/urls.py", line 8, in <module> url(r'^polls/',include('polls.urls', namespace="polls")), File "/Users/XXX/Desktop/djangostudy/django/django/conf/urls/__init__.py", line 44, in include 'Specifying a namespace in django.conf.urls.include() without ' django.core.exceptions.ImproperlyConfigured: Specifying a namespace in django.conf.urls.include() without providing an app_name is not supported. Set the app_name attribute in the included module, or pass a 2-tuple containing the list of patterns and app_name instead.
とエラーが出ました。
from django.conf.urls import include,url from django.contrib import admin from polls.views import index app_name="polls" urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^polls/',include('polls.urls', namespace="polls")), url(r'^$/',index,name='index'), ]
と書いても同じエラーが出ました。
どう直せばよいのでしょうか？

urls.pyを以下のようにし
python
1from django.conf.urls import include,url 2from django.contrib import admin 3from polls.views import index 4 5urlpatterns = [ 6 url(r'^admin/', admin.site.urls), 7 url(r'^polls/',include('polls.urls')), 8 url(r'^$/',index,name='index'), 9]
インクルードしているpolls/urls.pyに、app_name="polls" と定義してください。
