Long: `根据数据库连接配置生成模型代码，输出到 ./database，并支持基于 ./database/.transform.yaml 的类型/命名转换。
|
||
|
||
配置：通过 -c/--config 指定配置文件（默认 config.toml），从 [Database] 段读取：
|
||
Username, Password, Database, Host, Port, Schema, SslMode, TimeZone
|
||
|
||
行为：
|
||
- 解析 go.mod 以识别项目模块名
|
||
- 连接 PostgreSQL（gorm + postgres driver），校验连通性
|
||
- 调用 go.ipao.vip/gen 生成模型与相关文件到 ./database
|
||
- 根据 .transform.yaml 应用转换规则
|
||
|
||
示例：
|
||
atomctl gen -c config.toml model`,
|
||
RunE: commandGenModelE,
|
||
