=== Adding URLs to urls.py ===

 

 

ROOT_URLCONF = 'workshop_mysite.urls'

 

Time for an example. Edit mysite/urls.py so it looks like this:

This is worth a review. When somebody requests a page from your Web site -- say, "/polls/23/", Django will load the ''urls.py'' Python module, because it's pointed to by the ROOT_URLCONF setting. It finds the variable named urlpatterns and traverses the regular expressions in order. When it finds a regular expression that matches -- r'^polls/(?P<poll_id>\d+)/$' -- it loads the function detail() from polls/views.py. Finally, it calls that detail() function like so:

 

 

The '23' part comes from (\d+). Using parentheses around a pattern "captures" the text matched by that pattern and sends it as an argument to the view function; the \d+ is a regular expression to match a sequence of ''digits'' (i.e., a number).
