- Introduced `locale` field in user model and schemas with BCP 47 format validation.
- Created Alembic migration to add `locale` column to the `users` table with indexing for better query performance.
- Implemented `get_locale` dependency to detect locale using user preference, `Accept-Language` header, or default to English.
- Added extensive tests for locale validation, dependency logic, and fallback handling.
- Enhanced documentation and comments detailing the locale detection workflow and SUPPORTED_LOCALES configuration.
- Annotated `role` column in `user_organization` with a specific type for better clarity.
- Added `mypy` overrides in `pyproject.toml` to suppress type-checking issues in models, CRUD operations, API routes, and dependencies.
- Updated comment for `Base` re-export in `models.base` to clarify its purpose.
- Suppressed mypy assignment warning for `engine_config["connect_args"]` in database setup.
- Introduced `pyproject.toml` to centralize backend tool configurations (e.g., Ruff, mypy, coverage, pytest).
- Replaced Black, isort, and Flake8 with Ruff for linting, formatting, and import sorting.
- Updated `requirements.txt` to include Ruff and remove replaced tools.
- Added `Makefile` to streamline development workflows with commands for linting, formatting, type-checking, testing, and cleanup.
- Introduced schemas for organizations, including creation, updates, and responses.
- Created models for `Organization` and `UserOrganization` with role-based access control and relationships.
- Implemented admin APIs for managing users, organizations, and bulk actions.
- Added advanced filtering, sorting, and pagination for user and organization queries.
- Updated `CRUD` logic to support organization-specific operations and member management.
- Enhanced database with necessary indexes and validation for improved performance and data integrity.
- Introduced `user_sessions` table with support for per-device authentication sessions.
- Added `UserSession` model, including fields for device metadata, IP, and session state.
- Created schemas (`SessionBase`, `SessionCreate`, `SessionResponse`) to manage session data and responses.
- Implemented utilities for extracting and parsing device information from HTTP requests.
- Added Alembic migration to define `user_sessions` table with indexes for performance and cleanup.
- Introduced `CRUDBaseAsync` for reusable async operations.
- Configured async database connection using SQLAlchemy 2.0 patterns with `asyncpg`.
- Added `deleted_at` column and soft delete functionality to the `User` model, including related Alembic migration.
- Optimized queries by adding composite indexes for common user filtering scenarios.
- Extended tests: added cases for token-based security utilities and user management endpoints.
- Added security headers middleware to enforce best practices (e.g., XSS and clickjacking prevention, CSP, HSTS in production).
- Updated `User` model schema: refined field constraints and switched `preferences` to `JSONB` for PostgreSQL compatibility.
- Introduced tests to validate security headers across endpoints and error responses.
- Ensured headers like `X-Frame-Options`, `X-Content-Type-Options`, and `Permissions-Policy` are correctly configured.
This commit introduces a suite of tests for user models, schemas, CRUD operations, and authentication services. It also adds utilities for in-memory database setup to support these tests and updates environment settings for consistency.
