# Domain 层规范
|
|
|
|
## 实体定义
|
|
|
|
```go
|
|
package entity
|
|
|
|
import "mayfly-go/pkg/model"
|
|
|
|
type Db struct {
|
|
model.Model // 必须嵌入基础模型
|
|
model.ExtraData // 辅助字段（展示用、非查询条件）
|
|
|
|
Code string `json:"code" gorm:"size:32;not null;index:idx_db_code"`
|
|
Name string `json:"name" gorm:"size:255;not null;"`
|
|
InstanceId uint64 `json:"instanceId" gorm:"not null;"`
|
|
}
|
|
|
|
type Status int8
|
|
const (
|
|
StatusActive Status = 1
|
|
StatusInactive Status = 0
|
|
)
|
|
```
|
|
|
|
## ExtraData 使用原则
|
|
|
|
- ✅ **使用 ExtraData**: 前端展示字段、关联名称、状态文本、可选扩展信息
|
|
- 🚫 **必须独立字段**: 查询条件、排序字段、分组统计、索引字段、核心业务字段
|
|
|
|
## Repository 接口
|
|
|
|
```go
|
|
package repository
|
|
|
|
type Db interface {
|
|
base.Repo[*entity.Db]
|
|
GetDbList(condition *entity.DbQuery, orderBy ...string) (*model.PageResult[*entity.DbListPO], error)
|
|
}
|
|
```
