Django Form: NoReverseMatch

Getting an error: NoReverseMatch: Reverse for 'post_new' not found. 'post_new' is not a valid view function or pattern name.

my form in base.html:

> <form action="{% url 'post_new' %}" method="post">
>     {% csrf_token %}
>     Name:<br>
>     <input type="text" name="name"><br>
>     Text:<br>
>     <input type="text" name="text">
>     <input type="submit" value="Submit"> 
  </form>

views.py:

def post_new(request):
    posts = Post.objects.all()
    name = request.POST['name']
    print(name)
    return render(request, 'blog/base.html', {'posts': posts})

urls.py:

urlpatterns = [
    url(r'^$', views.base),
    url(r'^post_new/$', views.post_new, name='post_new'),
]

It seems that you might have an app in your Django project called blog. Assuming this is the case, you need to use namespaces. In your main urls.py file, you should have something like this: 

urlpatterns = [
    url(r'^blog/', include('blog.urls', namespace="blog")),
]

You can keep the urlpatterns the same in the urls.py under your blog app. With this namespace set you can reference the post_new view in your templates by doing the following:

<form action="{% url 'blog:post_new' %}" method="post">

This looks for the view called post_new in the blog app.
