Django - is not a registered namespace

I am trying to process a form in django/python using the following code. home.html: <form action="{% url 'home:submit' %}" method='post'> views.py: def submit(request): a = request.POST(['initial']) return render(request, 'home/home.html', { 'error_message': "returned" }) urls.py: from django.conf.urls import url from . import views urlpatterns = [ url(r'^submit/$', views.submit, name='submit') ] when I try to run it in a browser I get the error: NoReverseMatch at /home/ u'home' is not a registered namespace and another error message indicating a problem with the form.
You should just change you action url in your template: <form action="{% url 'submit' %} "method='post'> On the note of url namespaces... In order to be able to call urls using home namespace you should have in your main urls.py file line something like: for django 1.x: url(r'^', include('home.urls', namespace='home')), for django 2.x and 3.x path('', include(('home.urls', 'home'), namespace='home'))
