I am sorry I know this is an old topics.
But I spent the whole day and still unable to fix this problem.

Request Method:	GET
Request URL:	http://192.168.71.58:8007/1/
Django Version:	1.4
Exception Type:	NoReverseMatch
Exception Value:	Reverse for ''blog.views.add_comment'' with arguments '(1L,)' and keyword arguments '{}' not found. The following is my urls.py urlpatterns = patterns('', url(r'^admin/', include(admin.site.urls)), url(r'^(\d+)/$', 'blog.views.post'), url(r'^add_comment/(\d+)/', 'blog.views.add_comment'), ) my tempalte: <form action="{% url 'blog.views.add_comment' post.id %}" method="POST">{% csrf_token %} <div> Name: {{ form.author }} <p>{{ form.body|linebreaks }}</p> </div> <div><input type='submit' value='Submit'></div> </form> I tested the add_comment, it seems works. http://192.168.71.58:8007/add_comment/1/ It works. any idea? Thanks!!!

either remove the quotes from {% url 'blog.views.add_comment' %} (so it's {% url blog.views.add_comment %}) or {% load url from future %}

Loading from future is the better option, I think.

and for future reference:

Reverse for ''blog.views.add_comment'' with arguments '(1L,)' and keyword arguments '{}' not found.

notice how there's two single quotes there, not a double quote? that's your clue, right there

Tears!!!!!!!!!!!!!!!!!!!!!!!!
thanks!!!!!

But I am confused.
For example,
the following code needs to add single quote.

{% block content %}
<a href="{% url 'admin:todo_datetime_add' %}">Add Todo items</a>

Is there a link to give me detailed description?
I want to learn it and never get stuck again.

Thanks!!

In this case, you are using a 'named URL' in the Admin namespace. Here's two links that may help you learn a bit more about this topic.

also, that won't work with double quotes either, unless you import
future, and a bunch of other things.

Just import url from future, since this will be the default behavior
in the near future

Thanks.
I am going to read it.
Have a great weekend!
