From fc9885f859617bab36c971f4eaa56240741f52c4 Mon Sep 17 00:00:00 2001 From: John Estabrook Date: Tue, 24 Sep 2024 22:48:25 -0500 Subject: http-api: T6736: separate REST API and GraphQL API activation The GraphQL API was implemented as an addition to the existing REST API. As there is no necessary dependency, separate the initialization of the respective endpoints. Factor out the REST Pydantic models and FastAPI routes for symmetry and clarity. --- src/services/api/rest/models.py | 276 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 276 insertions(+) create mode 100644 src/services/api/rest/models.py (limited to 'src/services/api/rest/models.py') diff --git a/src/services/api/rest/models.py b/src/services/api/rest/models.py new file mode 100644 index 000000000..034e3fcdb --- /dev/null +++ b/src/services/api/rest/models.py @@ -0,0 +1,276 @@ +# Copyright 2024 VyOS maintainers and contributors +# +# This library is free software; you can redistribute it and/or +# modify it under the terms of the GNU Lesser General Public +# License as published by the Free Software Foundation; either +# version 2.1 of the License, or (at your option) any later version. +# +# This library is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
