From aaa46ef28230ca316a699b5e6cee96e424f1dc7a Mon Sep 17 00:00:00 2001 From: Misaka Date: Mon, 9 Feb 2026 22:39:14 +0800 Subject: [PATCH] feat: migrate configuration to .env environment variables This commit implements a complete migration from JSON-based configuration to .env environment variables, providing better security and flexibility. Key Changes: - Add python-dotenv dependency for environment variable support - Create config/env_loader.py with type conversion utilities - Add from_env() class methods to all config dataclasses - Update ConfigLoader to prioritize environment variables - Add save_to_env() method for .env file management - Implement database connection factory pattern - Add base DAO and connection classes for better abstraction - Support both SQL Server and MySQL with unified interface - Create migration script (scripts/migrate_to_env.py) - Update GUI to read/write .env files - Add comprehensive migration documentation New Files: - config/env_loader.py - Environment variable loader - db/base_connection.py - Base database connection interface - db/base_dao.py - Base DAO with common utilities - db/connection_factory.py - Factory for creating connections - db/mysql_connection.py - MySQL-specific connection - db/sqlserver_connection.py - SQL Server-specific connection - db/table_name_converter.py - SQL dialect converter - scripts/migrate_to_env.py - Configuration migration tool - docs/ENV_MIGRATION.md - Complete migration guide - .env.example - Environment variable template Testing: - Verified MySQL connection (8.0.44) - Tested all DAO operations - Confirmed 150 tables accessible - Validated configuration loading Co-Authored-By: Claude Sonnet 4.5 --- .gitignore | 6 +- config/defaults.py | 47 +-- config/env_loader.py | 201 ++++++++++++ config/loader.py | 118 ++++++- config/schema.py | 181 ++++++++++- db/base_connection.py | 84 +++++ db/base_dao.py | 100 ++++++ db/bip_users_dao.py | 148 +++++++-- db/connection.py | 219 ++++--------- db/connection_factory.py | 90 ++++++ db/discrete_material_plan_dao.py | 88 ++--- db/materials_to_be_deleted_dao.py | 316 ++++++++++++------ db/materials_to_be_deleted_records_dao.py | 373 ++++++++++++++++------ db/mysql_connection.py | 142 ++++++++ db/production_contract_data_dao.py | 51 ++- db/sqlserver_connection.py | 147 +++++++++ db/table_name_converter.py | 140 ++++++++ docs/ENV_MIGRATION.md | 262 +++++++++++++++ gui/config_manager.py | 19 +- gui/settings_tab.py | 148 +++++++-- requirements.txt | 2 + scripts/migrate_to_env.py | 226 +++++++++++++ 22 files changed, 2545 insertions(+), 563 deletions(-) create mode 100644 config/env_loader.py create mode 100644 db/base_connection.py create mode 100644 db/base_dao.py create mode 100644 db/connection_factory.py create mode 100644 db/mysql_connection.py create mode 100644 db/sqlserver_connection.py create mode 100644 db/table_name_converter.py create mode 100644 docs/ENV_MIGRATION.md create mode 100644 scripts/migrate_to_env.py diff --git a/.gitignore b/.gitignore index 7310a3a..6f39f13 100644 --- a/.gitignore +++ b/.gitignore @@ -21,4 +21,8 @@ tests/ # 用户配置文件（包含敏感信息） config/user_settings.json -nul \ No newline at end of file +nul + +# 环境变量 +.env +.env.local \ No newline at end of file diff --git a/config/defaults.py b/config/defaults.py index a30fe54..83b7a96 100644 --- a/config/defaults.py +++ b/config/defaults.py @@ -3,7 +3,7 @@ """ 默认配置值 -定义所有配置项的默认值。 +定义所有配置项的默认值，从环境变量加载。 """ from config.schema import ( ERPConfig, @@ -12,49 +12,14 @@ from config.schema import ( ExtractionConfig, ValidationConfig, AppConfig, + SQLServerConfig, + MySQLConfig, + DatabaseType, ) -# 默认配置 -DEFAULT_APP_CONFIG = AppConfig( -
