Django – is not a registered namespace


I am trying to process a form in django/python using the following code.


<form action="{% url 'home:submit' %}" method='post'>

def submit(request):
    a = request.POST(['initial'])
    return render(request, 'home/home.html', {
        'error_message': "returned"

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 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'))
