Positional parameters

Lets say we would like to make some pretty URLs for some lists that we have on our site. We have a "show_list" method that takes a user and an id as parameters. The "normal" way would be to have http://ourdomain.com/show_list?user=amix&id=13. But with positional paramteres, this can be written http://ourdomain.com/show_list/amix/13:

import cherrypy

class Root:

    def show_list(self, user, id):
        return "user: %s <br /> id: %s" % (user, id)
    show_list.exposed = True

cherrypy.quickstart(Root())

This also works well when you don't know the number of path components beforehand. Just take advantage of Python's arbitrary arguments:

class Root:

    def view(self, *path):
        return ", ".join(["(%s)" % p for p in path])
    view.exposed = True

Older versions

	replace this	with this
2.2	cherrypy.quickstart(Root())	cherrypy.root = Root() cherrypy.server.start()
2.0	import cherrypy	from cherrypy import cpg as cherrypy

You can read more about positional paramters for 2.2 in the CherryPy book (http://www.cherrypy.org/chrome/common/2.2/docs/book/chunk/index.html#id3326679)

CherryPy 2.1 allowed positional parameters for methods named "default".

CherryPy 2.0 had no allowance for positional parameters.
