Features:

...

Install:

go get github.com/astaxie/beego/orm

Quick Start

Simple Usage

package main

import (
	"fmt"
	"github.com/astaxie/beego/orm"
	_ "github.com/go-sql-driver/mysql" // import your used driver
)

// Model Struct
type User struct {
	Id   int    `orm:"auto"`
	Name string `orm:"size(100)"`
	orm.Manager
}

func init() {
	// register model
	orm.RegisterModel(new(User))

	// set default database
	orm.RegisterDataBase("default", "mysql", "root:root@/my_db?charset=utf8", 30)
}

func main() {
	o := orm.NewOrm()

	user := User{Name: "slene"}

	// insert
	id, err := o.Insert(&user)

	// update
	user.Name = "astaxie"
	num, err := o.Update(&user)

	// read one
	u := User{Id: user.Id}
	err = o.Read(&u)

	// delete
	num, err = o.Delete(&u)	
}

Next with relation

type Post struct {
	Id    int    `orm:"auto"`
	Title string `orm:"size(100)"`
	User  *User  `orm:"rel(fk)"`
	orm.Manager
}

var posts []*Post
qs := o.QueryTable("post")
num, err := qs.Filter("User__Name", "slene").All(&posts)

Use Raw sql

var maps []Params
num, err := o.Raw("SELECT id FROM user WHERE name = ?", "slene").Values(&maps)
if num > 0 {
	fmt.Println(maps[0]["id"])
}

Transaction

o.Begin()
...
user := User{Name: "slene"}
id, err := o.Insert(&user)
if err != nil {
	o.Commit()
} else {
	o.Rollback()
}
