In the Tutorial, part 3 when describing the url patterns and conf stuff,
for the polls.views.detail ....
This is worth a review. When somebody requests a page from your Web site
-- say, "/polls/23/", Django will load this 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:
detail(request=<HttpRequest object>, poll_id=''23')
The poll_id='23' part comes from (?P<poll_id>\d+). Using parentheses
around a pattern "captures" the text matched by that pattern and sends it
as an argument to the view function; the ?P<poll_id> defines the name that
will be used to identify the matched pattern; and \d+ is a regular
expression to match a sequence of digits (i.e., a number).
I suggest you change the poll_id to 1, 2, or 3 as this is what a user has
setup in the tutorial previously. poll_id = '23' will bring up the 404
code.
Not a big deal, but when just starting out, it is nice to see things work.
