Chapter 7 Unclear - patterns import not explained

[cspollar]

I could not find an explanation of why "patterns" is included in rango/urls.py. Previous and later examples of this file do not include "patterns".

The text in question is copied below.

Parameterised URL Mapping Now let’s have a look at how we actually pass the value of the category_name_url parameter to the category() function. To do so, we need to modify Rango’s urls.py file and update the urlpatterns tuple as follows.

urlpatterns = patterns('', url(r'^$', views.index, name='index'), url(r'^about/$', views.about, name='about'), url(r'^category/(?P[\w-]+)/$', views.show_category, name='show_category'),)

Hi! Well spotted. it is not needed. it should be:

urlpatterns = [ url(r'^$', views.index, name='index'), url(r'about/$', views.about, name='about'), url(r'^add_category/$', views.add_category, name='add_category'), url(r'^category/(?P[\w-]+)/$', views.show_category, name='show_category'), ]

I will update it shortly.

Thanks Leif
