NoReverseMatch in Django (url ploblem)

[Jeff Gaoey]

I'm a beginner of Django I want to set my url with database field_name 
instead of use primary key from Django tutorial. This is my code.

*mysite***dwru/urls.py**
urlpatterns = [
url(r'^$', include('product.urls', namespace="product")),]
*myapp***product/urls.py**
urlpatterns = [
   url(r'^$', views.index, name='index'),
   url(r'^(?P[-_\w]+)/$', views.product_list_from_index, 
name='catalog'),]
**product/views.py**def product_list_from_index(request, name_catalog):
   catalog = get_object_or_404(Catalog, name_catalog=name_catalog)
   context = {
   'catalog': catalog}
   return render(request,'product/product_list.html', context)

**product/models.py**class Catalog(models.Model):
  name_catalog = models.CharField(max_length=45)
  product = models.ManyToManyField(Product)
**template/product/index.html**{% for catalog in catalog_list %}
{{ 
catalog.name_catalog }}{% endfor %}

Then I add Catalog field with "TestCa01" then it shown an error

NoReverseMatch at /Reverse for 'catalog' with arguments '(u'TestCa01',)' and 
keyword arguments '{}' not found. 1 pattern(s) tried: 
[u'$(?P[-_\\w]+)/$']

it kind of some problem with this line in template

{% url 'product:catalog' catalog.name_catalog %}

any Idea?
