At the moment I have this URL working / /ter /graph I have an IndexPage(LivePage) with its def child_ter(self, ctx): return TerPage() def child_graph(self, ctx): return GraphPage() mehods. TerPage() an GraphPage() pick the firs element of a global list and show it in differents ways. I'd like now to enalble urls like /ter/1, /ter/2, /ter/n so the n element of the list is picked instead of the first one. How is the correct way to make that argument reach TerPage and GraphPage instances? Greets! -- Juanjo Conti

I really and truly hope not.
why not? urls are very important and using child_XXX methods is sometimes not very convinient. having a central place to set up urls makes it also possible to "reverse"-construct urls. like "give me the url to method XXX, with args X,Y,Z" that makes it very easy to change urls later on without going through all templates.

Convenience at the cost of maintainability is not worth it. Trust me, if your project is going to reach any kind of size, you do NOT want "django esque" URL dispatchers. I've seen it go bad, I've experienced it go bad.

FWIW, you can subclass your page objects to create more generic ways to deal with REST like arguments, as well as child page dispatch. This is what I do in Enamel: http://open.thusa.co.za/enamel/browser/trunk/enamel/pages.py#L68 http://open.thusa.co.za/enamel/browser/trunk/enamel/pages.py#L47 Then you can mix the page object appropriately and do something like class FooPage(rend.Page): # Whatever... class MyPage(pages.Standard): childPages = { 'Foo' : FooPage } arbitraryArguments = True def render_foo(self, c, d): return c.tag[ "You passed ", self.arguments[0], "instead of 'Foo'" ] HTH

sorry i can't trust you on that one, because i am involved in a very big project at the moment. i'm not allowed to talk about it yet, but i is probably the biggest application of python in austria (ok, that is not really hard ;) ) and i wrote a similar service (but way not as large) with nevow's traditional way of dealing with urls. and this one is very hard to maintain, because the url system is not abstracted out of the code and templates. so maintainability IS the reason i use a django like url dispatch system. i'm not a native speaker so convenience was probably the wrong word to choose. but it very much depends on the type of project. for some projects (also relatively large ones) it has been the right decision to stick with nevow's default way of handling urls.

I am reading at http://python.net/crew/mwh/nevowapi/nevow.rend.ChildLookupMixin.html Is there an error in childFactory doc? It mentions the segment and request parameters which aren't there. -- Juanjo Conti
