Okay, I got it.
There was a typo in the hard-coded url pattern. The following actually does
not work:
** code **
(r'^/1/add_random_samurai/$', self.admin_site.admin_view(
self.add_random_samurai))
** /code **
But this does:
** code **
(r'^1/add_random_samurai/$',
self.admin_site.admin_view(self.add_random_samurai))
** /code **
Basically, I added an extra slash and that's why it wasn't picking it up. So
to catch any number, I just use:
** code **
(r'^\d+/add_random_samurai/$',
self.admin_site.admin_view(self.add_random_samurai))
** / code **
I'm still not sure if this will create the samurai in the correct province.
I think I can extract this information from the request though. We shall
see.
