[Kimchi-devel] [PATCHv9 1/8] Support params for GET method

From: Royce Lv <lvroyce(a)linux.vnet.ibm.com&gt; GET filter parameter will be splited in two types: 1. flag_filter: pass to libvirt api and filter when resource query. flag_filters start with "_" 2. field_filter: take effect in filter out final result. field_filters are keys of dict returned by 'GET' Then we can call it like: GET /collection?filter_field=value Signed-off-by: Royce Lv <lvroyce(a)linux.vnet.ibm.com&gt; --- src/kimchi/control/base.py | 31 ++++++++++++++++++++++++------- src/kimchi/control/storagepools.py | 4 ++-- src/kimchi/control/storagevolumes.py | 2 +- 3 files changed, 27 insertions(+), 10 deletions(-) diff --git a/src/kimchi/control/base.py b/src/kimchi/control/base.py index 185c8d8..55678b1 100644 --- a/src/kimchi/control/base.py +++ b/src/kimchi/control/base.py @@ -212,10 +212,10 @@ class Collection(object): return res.get() - def _get_resources(self): + def _get_resources(self, flag_filter): try: get_list = getattr(self.model, model_fn(self, 'get_list')) - idents = get_list(*self.model_args) + idents = get_list(*self.model_args, **flag_filter) res_list = [] for ident in idents: # internal text, get_list changes ident to unicode for sorted @@ -234,19 +234,36 @@ class Collection(object): args = self.resource_args + [ident.decode("utf-8")] return self.resource(self.model, *args) - def get(self): - resources = self._get_resources() + def filter_data(self, resources, fields_filter): data = [] for res in resources: - data.append(res.data) + if all(key in res.data and res.data[key] == val \ + for key, val in fields_filter.iteritems()): + data.append(res.data) + return data + + def get(self, filter_params): + def _split_filter(params): + flag_filter = dict() + fields_filter = params + for key, val in params.items(): + if key.startswith('_'): + flag_filter[key] = fields_filter.pop(key) + return flag_filter, fields_filter + + flag_filter, fields_filter = _split_filter(filter_params) + resources = self._get_resources(flag_filter) + data = self.filter_data(resources, fields_filter) return kimchi.template.render(get_class_name(self), data) @cherrypy.expose - def index(self, *args): + def index(self, *args, **kwargs): method = validate_method(('GET', 'POST')) if method == 'GET': try: - return self.get() + filter_params = cherrypy.request.params + validate_params(filter_params, self, 'get_list') + return self.get(filter_params) except InvalidOperation, param: error = "Invalid operation: '%s'" % param raise cherrypy.HTTPError(400, error) diff --git a/src/kimchi/control/storagepools.py b/src/kimchi/control/storagepools.py index 782f5a6..e3236a7 100644 --- a/src/kimchi/control/storagepools.py +++ b/src/kimchi/control/storagepools.py @@ -63,9 +63,9 @@ class StoragePools(Collection): return resp - def _get_resources(self): + def _get_resources(self, filter_params): try: - res_list = super(StoragePools, self)._get_resources() + res_list = super(StoragePools, self)._get_resources(filter_params) # Append reserved pools isos = getattr(self, ISO_POOL_NAME) isos.lookup() diff --git a/src/kimchi/control/storagevolumes.py b/src/kimchi/control/storagevolumes.py index d541807..cd15bcc 100644 --- a/src/kimchi/control/storagevolumes.py +++ b/src/kimchi/control/storagevolumes.py @@ -70,7 +70,7 @@ class IsoVolumes(Collection): super(IsoVolumes, self).__init__(model) self.pool = pool - def get(self): + def get(self, filter_params): res_list = [] try: get_list = getattr(self.model, model_fn(self, 'get_list')) -- 1.8.1.2
