From: David Garcia Date: Tue, 25 Aug 2020 14:10:07 +0000 (+0200) Subject: Change add_relation function in libjuju.py to accept saas X-Git-Tag: release-v9.0-start~24 X-Git-Url: https://osm.etsi.org/gitweb/?a=commitdiff_plain;h=refs%2Fchanges%2F39%2F9639%2F4;p=osm%2FN2VC.git Change add_relation function in libjuju.py to accept saas Before, app_1, endpoint1, app_2, endpoint2 parameters were needed. Now we directly pass the endpoint names of the relation with the right format. If "app:endpoint", it is understood that the endpoint it of a charm in the current model. If "name", it is understood that the endpoint is a consumed endpoint from another model. This function allows to cross-model-relate charms to external models Change-Id: I84ab45ba735a1960ab742d9ec731c357ec1042c6 Signed-off-by: David Garcia --- diff --git a/n2vc/libjuju.py b/n2vc/libjuju.py index d8b0858..ceb5e02 100644 --- a/n2vc/libjuju.py +++ b/n2vc/libjuju.py @@ -705,21 +705,18 @@ class Libjuju: async def add_relation( self, model_name: str, - application_name_1: str, - application_name_2: str, - relation_1: str, - relation_2: str, + endpoint_1: str, + endpoint_2: str, ): """Add relation - :param: model_name: Model name - :param: application_name_1 First application name - :param: application_name_2: Second application name - :param: relation_1: First relation name - :param: relation_2: Second relation name + :param: model_name: Model name + :param: endpoint_1 First endpoint name + ("app:endpoint" format or directly the saas name) + :param: endpoint_2: Second endpoint name (^ same format) """ - self.log.debug("Adding relation: {} -> {}".format(relation_1, relation_2)) + self.log.debug("Adding relation: {} -> {}".format(endpoint_1, endpoint_2)) # Get controller controller = await self.get_controller() @@ -727,13 +724,9 @@ class Libjuju: # Get model model = await self.get_model(controller, model_name) - # Build relation strings - r1 = "{}:{}".format(application_name_1, relation_1) - r2 = "{}:{}".format(application_name_2, relation_2) - # Add relation try: - await model.add_relation(relation1=r1, relation2=r2) + await model.add_relation(endpoint_1, endpoint_2) except JujuAPIError as e: if "not found" in e.message: self.log.warning("Relation not found: {}".format(e.message)) diff --git a/n2vc/n2vc_juju_conn.py b/n2vc/n2vc_juju_conn.py index 690d3be..31bdd6e 100644 --- a/n2vc/n2vc_juju_conn.py +++ b/n2vc/n2vc_juju_conn.py @@ -709,10 +709,8 @@ class N2VCJujuConnector(N2VCConnector): try: await self.libjuju.add_relation( model_name=model_1, - application_name_1=app_1, - application_name_2=app_2, - relation_1=endpoint_1, - relation_2=endpoint_2, + endpoint_1="{}:{}".format(app_1, endpoint_1), + endpoint_2="{}:{}".format(app_2, endpoint_2), ) except Exception as e: message = "Error adding relation between {} and {}: {}".format( diff --git a/n2vc/tests/unit/test_libjuju.py b/n2vc/tests/unit/test_libjuju.py index 27f0454..a789bc8 100644 --- a/n2vc/tests/unit/test_libjuju.py +++ b/n2vc/tests/unit/test_libjuju.py @@ -670,9 +670,7 @@ class AddRelationTest(LibjujuTestCase): mock_add_relation.side_effect = JujuAPIError(result) self.loop.run_until_complete( - self.libjuju.add_relation( - "model", "app1", "app2", "relation1", "relation2", - ) + self.libjuju.add_relation("model", "app1:relation1", "app2:relation2",) ) mock_warning.assert_called_with("Relation not found: not found") @@ -696,9 +694,7 @@ class AddRelationTest(LibjujuTestCase): mock_add_relation.side_effect = JujuAPIError(result) self.loop.run_until_complete( - self.libjuju.add_relation( - "model", "app1", "app2", "relation1", "relation2", - ) + self.libjuju.add_relation("model", "app1:relation1", "app2:relation2",) ) mock_warning.assert_called_with("Relation already exists: already exists") @@ -719,9 +715,7 @@ class AddRelationTest(LibjujuTestCase): with self.assertRaises(JujuAPIError): self.loop.run_until_complete( - self.libjuju.add_relation( - "model", "app1", "app2", "relation1", "relation2", - ) + self.libjuju.add_relation("model", "app1:relation1", "app2:relation2",) ) mock_disconnect_controller.assert_called_once() @@ -738,13 +732,31 @@ class AddRelationTest(LibjujuTestCase): mock_get_model.return_value = juju.model.Model() self.loop.run_until_complete( - self.libjuju.add_relation( - "model", "app1", "app2", "relation1", "relation2", - ) + self.libjuju.add_relation("model", "app1:relation1", "app2:relation2",) + ) + + mock_add_relation.assert_called_with( + "app1:relation1", "app2:relation2" + ) + mock_disconnect_controller.assert_called_once() + mock_disconnect_model.assert_called_once() + + def test_saas( + self, + mock_add_relation, + mock_disconnect_controller, + mock_disconnect_model, + mock_get_model, + mock_get_controller, + ): + mock_get_model.return_value = juju.model.Model() + + self.loop.run_until_complete( + self.libjuju.add_relation("model", "app1:relation1", "saas_name",) ) mock_add_relation.assert_called_with( - relation1="app1:relation1", relation2="app2:relation2" + "app1:relation1", "saas_name" ) mock_disconnect_controller.assert_called_once() mock_disconnect_model.assert_called_once()
