Our idea is to convert an incoming OCCI request into an OpenStack request, so that we can pass it downstream so as to be processed by nova. However, we should call the final application in each of the controlers instead of just modifying the request, in order to be able to process the response from nova and "re-occi-fy" it. In order to do so, the controllers should receive the application. - This change modifies the BaseController so that in receives the app. If the controller returns a response (because it calls the application, gets the response and process it or by any other reason), that response will be used. If it returns None, the application will be called. - Also modifies the compute controller so that it implements the create_resources() function.
- Rename ooi.api.compute.ComputeController to ooi.api.compute.Controller - Move ooi.api.BaseController to ooi.api.base.Controller
OpenStack does some checks searching for a version string in the URL, so we need to change the script path in the request to match what they're looking for. This change modifies the controllers so that they receive the version, and adds a helpher method that prepares the request for passing it down to the application.
Depending on what OCCI objects we have and depending on the rendering we should render one thing or another. This collection should be used to do so. Currently only supports the rendering of collections of resources, that are rendered to their locations in both text/occi and text/plain
Build the location, based on its kind location and their uuid
With the new code the controllers should call the application themselves, get the response, and "re-occi-fy" it. We do this in the compute controller so we call nova, capture the response, parse it, build the OCCI objects and return an OCCI collection so that it is properly rendered.
Still missing the creation of links and mixins of the compute resource.
Fix tests. Use a dictionary for the responses of the fake app. Moved function to openstack.helpers.

Based on the compute one, includes tests.

This needs rebasing after merging the compute part. |
