Types

type Controller

type Controller interface {
	// add update 验证
	Validator() error
	//添加数据生成uuid
	SetCode() error
	//添加数据绑定用户id
	SetUser(c *gin.Context, data interface{}) error

	// 表名
	TableName() string
	// 自身实例 用于found one
	Object() interface{}
	// 自身实例 用于found list
	Objects() interface{}

	// 以下三个方法用于辅助默认方法实现curd，过于复杂的直接override
	// Where 搜索条件
	// Search(db *gorm.DB, key string) *gorm.DB
	// 查询的补充条件
	Joins(db *gorm.DB) *gorm.DB
	// 处理列表返回结果
	Result(data interface{}) interface{}
}
