Functions

func DiffModel

func DiffModel(curr, prev interface{}) []string

DiffModel 模型差异对比，返回gorm命名规范的更新数据 支持以下类型比对：常规数据类型(bool, int, float, string, time.Time)，嵌套可导出的非指针的 struct

func RegisterConverter

func RegisterConverter(entity ddd.IEntity, converter IConverter)

RegisterConverter 使用时直接 mysql.RegisterConverter(&do{}, converter)

func RegisterEntity2Model

func RegisterEntity2Model(entity ddd.IEntity, f1 Entity2Model, f2 Model2Entity)
