regex URL mapping

[Tomas Brabenec]

Hi all,

how can I use regular expression for url mapping?
In CP wiki is this example:

## example begin

def root_index(name):
return "Hello, %s!" % name

def branch_leaf(size):
return str(int(size) + 3)

mappings = [
(r'^/([^/]+)$', root_index),
(r'^/branch/leaf/(\d+)$', branch_leaf),
]

## example end


If I try add this to my code, its not working:


## code begin

import cherrypy

from context import Index
from context import Page2
from context import Page3

## Old mapping
#root = Index.Index()
#root.pg2 = Page2.Page2()
#root.pg2.edit = Page2.Edit()
#root.pg3 = Page3.Page3()
#cherrypy.tree.mount(root)

## New mapping
mappings = [
(r'^/([^/]+)$', Index.Index()),
(r'^/pg2(\d+)-(.*)/$', Page2.Page2()),
(r'^/pg2-edit(\d+)-(.*)/$', Page2.Edit()),
(r'^/pg3/$', Page3.Page3())
]
cherrypy.tree.mount(mappings)

if __name__ == '__main__':
import os.path
thisdir = os.path.dirname(__file__)
cherrypy.quickstart(config=os.path.join(thisdir, 'tutorial.conf'))

## code end


Where is a problem?

Now, I try use Routes, but in this not working regular expression :-(

## code begin

import cherrypy

from context import Index
from context import Page2
from context import Page3

d = cherrypy.dispatch.RoutesDispatcher()

m = d.mapper
m.explicit = True
m.minimization = False
d.connect('index', '/', controller=Index.Index(), action='index')
d.connect('pg2', r'/pg2-(\d+)-(.*)/$', controller=Page2.Page2(),
action='index') # url example: http://myserver/pg2-1234-astalavista/
d.connect('pg2_edit', r'/pg2-edit-(\d+)-(.*)/$',
controller=Page2.Edit(), action='index') # url example:
http://myserver/pg2-edit-54-astalavista/
d.connect('pg3', '/pg3/$', controller=Page3.Edit(), action='index')

conf = {'/' : {'request.dispatch' : d}}
cherrypy.tree.mount(root=None, config=conf)

cherrypy.engine.start()

## code end

URLs "/" and "/pg3/" works correctly, but URLs with regular expression
not working (I get 404 Not Found), why?

Any idea ?

Here is resolution for my problem:

d.connect('pg2', '/pg2-{oid:(\d+)}-{name:(\w+)}/',
controller=Page2.Page2(), action='index')
d.connect('pg2_edit', '/pg2-edit-{oid:(\d+)}-{name:(\w+)}/',
controller=Page2.Edit2(), action='index')

or

d.connect('pg2', '/pg2-{oid}-{name}', controller=Page2.Page2(),
action='index', requirements=dict(oid=r"\d+", name=r"\w+"))
d.connect('pg2_edit', '/pg2-edit-{oid}-{name}/',
controller=Page2.Edit2(), action='index', requirements=dict(oid=r"\d+",
name=r"\w+"))

If you need regex you may want to look at selector:
