From 16ee4e0cb3a9eda0dd753e77829562833d7e3db3 Mon Sep 17 00:00:00 2001 From: Felipe Cardoso Date: Tue, 25 Nov 2025 00:37:23 +0100 Subject: [PATCH] Initial implementation of OAuth models, endpoints, and migrations - Added models for `OAuthClient`, `OAuthState`, and `OAuthAccount`. - Created Pydantic schemas to support OAuth flows, client management, and linked accounts. - Implemented skeleton endpoints for OAuth Provider mode: authorization, token, and revocation. - Updated router imports to include new `/oauth` and `/oauth/provider` routes. - Added Alembic migration script to create OAuth-related database tables. - Enhanced `users` table to allow OAuth-only accounts by making `password_hash` nullable. --- .../versions/d5a7b2c9e1f3_add_oauth_models.py | 144 ++++ backend/app/api/main.py | 14 +- backend/app/api/routes/oauth.py | 433 ++++++++++++ backend/app/api/routes/oauth_provider.py | 312 +++++++++ backend/app/core/config.py | 54 ++ backend/app/crud/__init__.py | 10 +- backend/app/crud/oauth.py | 653 ++++++++++++++++++ backend/app/models/__init__.py | 8 + backend/app/models/oauth_account.py | 55 ++ backend/app/models/oauth_client.py | 67 ++ backend/app/models/oauth_state.py | 45 ++ backend/app/models/user.py | 16 +- backend/app/schemas/oauth.py | 313 +++++++++ backend/app/services/__init__.py | 5 + backend/app/services/oauth_service.py | 598 ++++++++++++++++ backend/pyproject.toml | 7 + backend/tests/api/test_oauth.py | 394 +++++++++++ backend/tests/core/test_config.py | 13 +- backend/tests/crud/test_oauth.py | 537 ++++++++++++++ backend/tests/models/test_user.py | 21 +- backend/tests/services/test_oauth_service.py | 403 +++++++++++ backend/tests/test_init_db.py | 6 + backend/uv.lock | 14 + 23 files changed, 4109 insertions(+), 13 deletions(-) create mode 100644 backend/app/alembic/versions/d5a7b2c9e1f3_add_oauth_models.py create mode 100644 backend/app/api/routes/oauth.py create mode 100644 backend/app/api/routes/oauth_provider.py create mode 100644 backend/app/crud/oauth.py create mode 100644 backend/app/models/oauth_account.py create mode 100644 backend/app/models/oauth_client.py create mode 100644 backend/app/models/oauth_state.py create mode 100644 backend/app/schemas/oauth.py create mode 100644 backend/app/services/oauth_service.py create mode 100644 backend/tests/api/test_oauth.py create mode 100644 backend/tests/crud/test_oauth.py create mode 100644 backend/tests/services/test_oauth_service.py diff --git a/backend/app/alembic/versions/d5a7b2c9e1f3_add_oauth_models.py b/backend/app/alembic/versions/d5a7b2c9e1f3_add_oauth_models.py new file mode 100644 index 0000000..8e5e897 --- /dev/null +++ b/backend/app/alembic/versions/d5a7b2c9e1f3_add_oauth_models.py @@ -0,0 +1,144 @@ +"""add oauth models + +Revision ID: d5a7b2c9e1f3 +Revises: c8e9f3a2d1b4 +Create Date: 2025-11-24 20:00:00.000000 + +""" + +from collections.abc import Sequence + +import sqlalchemy as sa +from alembic import op +from sqlalchemy.dialects import postgresql + +# revision identifiers, used by Alembic. +revision: str = "d5a7b2c9e1f3" +down_revision: str | None = "c8e9f3a2d1b4" +branch_labels: str | Sequence[str] | None = None +depends_on: str | Sequence[str] | None = None + + +def upgrade() -> None: + # 1.
