Method Details

getChild(self, path, request)

Retrieve a 'child' resource from me.

Implement this to create dynamic resource generation -- resources which are always available may be registered with self.putChild().

This will not be called if the class-level variable 'isLeaf' is set in your subclass; instead, the 'postpath' attribute of the request will be left as a list of the remaining path elements.

For example, the URL /foo/bar/baz will normally be:
 | site.resource.getChild('foo').getChild('bar').getChild('baz').
However, if the resource returned by 'bar' has isLeaf set to true, then the getChild call will never be made on it.
Parameters:
path - a string, describing the child
request - a twisted.web.server.Request specifying meta-information about the request that is being made for this child.
Overrides:
twisted.web.resource.Resource.getChild (inherited documentation)

loadModel(self, path, request)

Load a model, for the given path and request.
Returns:
Deferred

loadModelNow(self, path, request)

Override this rather than loadModel if your model-loading is synchronous.
