Remove it.

-Adding-A-Method-To-The-Openstack-Api - -==================================== -The interface is a mostly RESTful API. REST stands for Representational State Transfer and provides an architecture "style" for distributed systems using HTTP for transport. Figure out a way to express your request and response in terms of resources that are being created, modified, read, or destroyed. - -
-
-Routing - -------- -To map URLs to controllers+actions, OpenStack uses the Routes package, a clone of Rails routes for Python implementations. See http://routes.groovie.org/ for more information. -URLs are mapped to "action" methods on "controller" classes in ``cinder/api/openstack/__init__/ApiRouter.__init__`` . -See http://routes.groovie.org/manual.html for all syntax, but you'll probably just need these two: - - mapper.connect() lets you map a single URL to a single action on a controller. - - mapper.resource() connects many standard URLs to actions on a controller. - -
-
-Controllers-And-Actions - ------------------------ -Controllers live in ``cinder/api/openstack``, and inherit from cinder.wsgi.Controller. -See ``cinder/api/openstack/servers.py`` for an example. -Action methods take parameters that are sucked out of the URL by mapper.connect() or .resource(). The first two parameters are self and the WebOb request, from which you can get the req.environ, req.body, req.headers, etc. - -
-
-Serialization - -------------- -Actions return a dictionary, and wsgi.Controller serializes that to JSON or XML based on the request's content-type. -If you define a new controller, you'll need to define a ``_serialization_metadata`` attribute on the class, to tell wsgi.Controller how to convert your dictionary to XML. It needs to know the singular form of any list tag such as ``[servers]`` list contains ``[server]`` tags, and which dictionary keys are to be XML attributes as opposed to subtags such as ``[server id="4"/]`` instead of ``[server][id]4[/id][/server]``. -See `cinder/api/openstack/servers.py` for an example. -Faults ------- -If you need to return a non-200, you should -return faults.Fault(webob.exc.HTTPNotFound()) - -
