[PATCHv5 0/8] Storage server and targets support
From: Royce Lv <lvroyce@linux.vnet.ibm.com> v4>v5, remove storage server list reload function, merge storage server and targets v3>v4, fix inconsistency between doc and json schema v1>v3, fix racing problem, fix style. Add parameters to GET request so that we will query storage server as: /storageservers?target_type=netfs Query all servers of any type supported(now only netfs): /storageservers Query all storage targets on a server: /storageservers/host-name/storagetargets Query a given type of storage targets: /storageservers/host-name/storagetargets?target_type=netfs Royce Lv (8): Support params for GET method Add testcase for GET param Storage server: Update API.md storage server: update controller.py storage server: Update model and mockmodel storage target: Update API.md storage target: Update controller and json schema storage target: Add model support docs/API.md | 22 +++++++++++ src/kimchi/API.json | 20 ++++++++++ src/kimchi/control/base.py | 8 ++-- src/kimchi/control/storageserver.py | 63 +++++++++++++++++++++++++++++++ src/kimchi/control/utils.py | 2 + src/kimchi/mockmodel.py | 28 ++++++++++++++ src/kimchi/model.py | 74 +++++++++++++++++++++++++++++++++++++ src/kimchi/root.py | 2 + tests/test_rest.py | 37 +++++++++++++++++++ 9 files changed, 253 insertions(+), 3 deletions(-) create mode 100644 src/kimchi/control/storageserver.py -- 1.8.1.2

you have get and validate in father class once _get_resources Here you get and validate it in child class.
why not in father:
@cherrypy.expose def index(self, *args): method = validate_method(('GET', 'POST')) if method == 'GET': params = parse_param() validate_params(params, self, 'get_list') try: return self.get(params) I reload this method because we don't want a get_list, then iterate each element because targets can be fetched at a time. But I think your suggestion is valuable, and I'm working on split the get() method in controller to adjust these scenerios so that we don't need to regularly reload class without need of writing get for Resource.
