  • 多模式配置文件

配置方式: conf/app.yaml 中 devMode = dev 对应conf/app-dev.yaml

GetDevMode

    type dba struct {
    	User        string
    	Password    string
    	Host        string
    	Name        string
    	MaxIdleConn int
    	MaxOpenConn int
    	// db log mode
    	Log bool
    }
    config := gt.Configger()
    dbS := &dba{
        user:     config.GetString("app.db.user"),
        password: config.GetString("app.db.password"),
        host:     config.GetString("app.db.host"),
        name:     config.GetString("app.db.name"),
    }
    // or
    dbS := &dba{}
    gt.Configger().GetStruct("app.db", dbS)

CacheManager

    ce = gt.NewCache()
    data := CacheModel{
		Time: 50 * CacheMinute,
		Data: user,
	}

	// key can use user.ID,user.Name,user
	// because it can be interface
	// set
	err := ce.Set(user, data)
	t.Log("set err: ", err)

	// get
	reply, _ := ce.Get(user)
	t.Log("user data :", reply.Data)

AesEnDe

log.Println("[加密测试]:", AesEn("123456"))
log.Println("[解密测试]:", AesDe("lIEbR7cEp2U10gtM0j8dCg=="))

Time

// 时间格式化2006-01-02 15:04:05
type CTime time.Time
// 时间格式化2006-01-02
type CDate time.Time

JSONType

// 返回json类型
type CJSON []byte

Validator

func TestValidator(t *testing.T) {

	type Test struct {
		ID   int64  `json:"id" valid:"required,min=0,max=5"`
		Name string `json:"name" valid:"required,len=2-5" trans:"用户名"`
	}

	// form request data
	var maps = make(map[string][]string)
	maps["name"] = append(maps["name"], "梦1")
	info := Valid(maps, Test{})
	log.Println(info)

	// json request data
	var test = Test{
		ID:   6,
		Name: "梦1",
	}
	log.Println(Valid(test, Test{}))

}

CustomLog

func TestNewFileLog(t *testing.T) {

	myLog.Info("项目路径", projectPath)
	for {
		time.Sleep(1 * time.Second)
		myLog.Error("测试")
	}
}

SnowflakeId

func TestId(t *testing.T) {
	id, err := NewID(1)
	if err != nil {
		log.Print(err)
		return
	}
	t.Log(id.String())
}

前提: 运行nsq, 参考docker-compose.yaml

Extend Examples

Crud Selectsql

    sql := "update `user` set name=? where id=?"
    t.Log("[Info]:", crud.Select(sql, "梦sql", 1).Exec())
    var user []*User
	cd := crud.Params(
		Data(&user),
		//ClientPage(1), // serch()分页需要
		//EveryPage(2),
	).
		Select("select *from user").
		Select("where id > 0")
	if true {
		cd.Select("and 1=1")
	}
	cd.Search() // 查询 + 分页
    t.Log(crud.Pager()) // Search()分页数据
	//cd.Single() // 注释Search使用Single()直接查询

Crud Update

    type UserPar struct {
		Name string `json:"name"`
	}
	crud := crud.Params(
		//Table("user"),
		Model(User{}),
		Data(&UserPar{
			//ID:   1,
			Name: "梦S",
		}),
	)
	t.Log(crud.Update().RowsAffected())
	t.Log(crud.Select("`name` = ?", "梦").Update().RowsAffected())
	t.Log(crud.Error())

Transcation

    cd := crud.Begin()
	cd.Params(
		Table("user"),
		Data(&User{
			ID:   11234,
			Name: "梦S",
		}),
	).Create()
	if cd.Error() != nil {
		cd.Rollback()
	}
	cd.Params(
		Data(&User{
			Name: "梦SSS2",
		})).Create()
	if cd.Error() != nil {
		cd.Rollback()
	}
	// add select sql test
	var u []User
	cd.Params(Data(&u)).Select("select * from `user`").Select("where 1=1").Single()
	cd.Params(Data(&u)).Select("select * from `user`").Select("where 1=1").Single()
	//cd.DB().Raw("select * from `user`").Scan(&u)

	cd.Commit()
	if cd.Error() != nil {
		cd.Rollback()
	}

Use Gorm

模型定义需遵循:模型定义

// example 1:
// 根据模型定义自动生成表
gt.NewDBTool().AutoMigrate(&User{},&Order{})
// 直接使用gorm:
db := gt.NewCrud().DB()

Mock Data

使用mock参数, 生成随机数据, 将不会进行数据库查询

    GetBySearch(params cmap.CMap) Crud     // search
    GetByData(params cmap.CMap) Crud       // get data no search
    GetMoreBySearch(params cmap.CMap) Crud // more search    
    // 以上三种支持mock参数,传递的参数mock=1即可

Crud clone

// 关于crud的
一个crud = gt.NewCrud()对象中的参数是共享的,通用的增删改查针对同一张表可复用  
如果进行了表关联或改变了模型, 需要重新cd = gt.NewCrud(),否则继续使用crud容易影响到其他使用这个变量的地方

ps:
1.不支持CJSON类型, 请使用tag: faker:"-"进行过滤
2.不支持图片等实体文件数据
3.默认随机生成,如有长度等其他要求,请参考:faker_test

  • 约定
    1.模型结构体json 内容与表字段保持一致
    2.返回格式参考result
    3.多表关联命名, 模型中其他表字段命名: 他表名 + "_" + 他表字段名
    n....
