entari-plugin-database

Entari plugin for SQLAlchemy ORM

功能

提供数据库服务支持，管理多个数据库连接
依赖注入会话与 ORM 模型数据
依据类型注解或 SQLDepends 的复杂依赖关系注入
- 例如 Sequence[Model] 会注入所有模型
- 声明 SQLDepends(select(Model).where(Model.field == value)) 会注入查询结果
- 通过配合 arclet.entari.param, 可以在 SQLDepends 的查询语句中使用 param 声明其他的依赖注入参数
自动数据库迁移
- 通过 alembic 实现
- 检测到模型变更时，自动生成并应用迁移脚本
- 根据模型的 __bind_key__ 属性，支持多数据库迁移
- 允许开发者自定义迁移脚本

多数据库

插件配置项 binds 可以根据 bind_key 声明多个数据库连接
ORM 模型可以通过 __bind_key__ 属性指定使用哪个数据库连接
默认数据库连接使用 "" 作为 bind_key

迁移

ORM 模型的变更会被自动检测并生成迁移脚本
本插件会根据模型的结构自动计算 revision
ORM 模型可以声明 __revision__ 属性来指定特定的 revision
迁移记录将存储在用户目录下的 .entari/data/database/migrations_lock.json 文件中
