You are going down the wrong path. You do not want to enumerate all
existing job values that might appear in url path segment in your URLConf.
Rather you want to describe via a regular expression what a job value might
look like, and put that in the url pattern. If you have not run through the
tutorial I would suggest you do so, as it covers this subject. In
particular I'd suggest you carefully go through:
http://docs.djangoproject.com/en/dev/intro/tutorial03/#design-your-urls
