According to the error, your pattern starts with $, which is an obvious mistake.

But the "url.py" you quote has ^.

Maybe it was using an old version, or you haven't copied the right one.

Greetings,

Dear Luis,

FYI:

post_detail.html
-----------------------
{% extends "blog/base.html" %}

{% block content %}
    <div class="post">
        {% if post.published_date %}
            <div class="date">
                {{ post.published_date }}
            </div>
        {% endif %}
        <h1>{{ post.title }}</h1>
        <p>{{ post.text|linebreaks }}</p>
    </div>
{% endblock %}

post_list.html
--------------------
{% extends "blog/base.html" %}
{% block content %}
{% for post in posts %}
    <div class="post">
        <h1><a href="{% url "post_detail" pk=post.pk %}">{{ post.title }}</a></h1>
        <p align="justify">{{ post.text|linebreaks }}</p>
        <p align="right" class="date">Web published: {{ post.published_date }}</p>
    </div>
{% endfor %}
{% endblock content %}

Thanks in Advance,

Sankar B

<h1><a href="{% url "post_detail" pk=post.pk %}">{{ post.title }}</a></h1>

try:

<h1><a href="{% url "post_detail" post.pk %}">{{ post.title }}</a></h1>

If not found then check your project url.py , do you have something like


urlpatterns = [
    url(r'^$', include('myapp.urls') ),
    ....
]

As Remco said your problem are with your pattern because starts with $ or have  ^$

[projectname]/
├── [projectname]/
│   ├── __init__.py
│   ├── settings.py
│   ├── urls.py     <--  The error is here 
│   └── wsgi.py
└── manage.py
└── blog/
       └── __init__.py
       └── models.py
       └── managers.py
       └── views.py
       └── urls.py

In the urls.py do you have somethig like this ?

urlpatterns = patterns('',
    url(r'^$', include('blog.urls')),    <--  The error is here 
    url(r'^admin/', include(admin.site.urls)),
)
