childFactory(self, ctx, name)Used by locateChild to return children which are generated dynamically. Note that higher level interfaces use only locateChild, and only nevow.rend.Page.locateChild uses this. segment is a string represnting one element of the URI. Request is a nevow.appserver.NevowRequest. The default implementation of this always returns None; it is intended to be overridden. |
getDynamicChild(self, segment, request)Deprecated, use childFactory instead. The name is different and the order of the arguments is reversed. |
locateChild(self, ctx, segments)Locate a child page of this one. ctx is a nevow.context.PageContext representing the parent Page, and segments is a tuple of each element in the URI. An tuple (page, segments) should be returned, where page is an instance of nevow.rend.Page and segments a tuple representing the remaining segments of the URI. If the child is not found, return NotFound instead. locateChild is designed to be easily overridden to perform fancy lookup tricks. However, the default locateChild is useful, and looks for children in three places, in this order: - in a dictionary, self.children - a member of self named child_<childname>. This can be either an attribute or a method. If an attribute, it should be an object which can be adapted to IResource. If a method, it should take the context and return an object which can be adapted to IResource. - by calling self.childFactory(ctx, name). Name is a single string instead of a tuple of strings. This should return an object that can be adapted to IResource.
