	redis "github.com/eehsiao/go-models-redis"
)

// User : json struct that to store into redis
type User struct {
	Host       string `json:"host"`
	User       string `json:"user"`
	SelectPriv string `json:"select_priv"`
}

//new redis dao
redUserModel := &RedUserModel{
    Dao: redis.NewDao().SetConfig("127.0.0.1:6379", "", 0).OpenDB(),

How-to

How to design model data logical

Redis

1.

create a data struct, and add the tag json:"name"

type User struct {
	Host       string `json:"host"`
	User       string `json:"user"`
	SelectPriv string `json:"select_priv"`
	IntVal     int    `json:"user,string"`
}

if you have integer value, you can add a transfer type desc. such as json:"user,string"

2.

create redis dao

m := redis.NewDao().SetConfig("127.0.0.1:6379", "", 0).OpenDB()

3.

directly use the go-redis command function

redBool, err = m.HSet(userTable, redKey, serialStr).Result()
