Beego ———— orm实现获取数据并写入到数据库中

新建一个controller文件，当用户访问http://localhost:8080/registe这个地址时提交get，get方法返回一个页面让用户填写数据并post提交，post获得数据，并解析，我写了两种方式，一个是，根据关键词，并初始化一个新的结构体，让其插入到数据库中，

package controllers

import (
	"github.com/astaxie/beego"
	"fmt"
	_ "demo2/models"
	"demo2/models"
	"github.com/astaxie/beego/orm"
)

type Demo4Controlle struct {
	beego.Controller
}

func (this *Demo4Controlle) Get() {

	this.TplName = "register.html"
}


func (this *Demo4Controlle)Post(){

	user := models.User{}

	err := this.ParseForm(&user)
	if err!= nil {
		this.Ctx.WriteString("获取表格失败！"+fmt.Sprint(err))
	}else {
		orm:=orm.NewOrm()

		_, e := orm.Insert(&user)
		if e != nil {

			this.Ctx.WriteString("插入失败！" + fmt.Sprint(e))
		} else {

			this.Ctx.WriteString("插入成功!")
		}


	}

}




func (this *Demo4Controlle) Post1() {

	name := this.GetString("name")
	nickname := this.GetString("nickname")
	password := this.GetString("password")
	age, e := this.GetInt("age")
	if e != nil {
		this.Ctx.WriteString("年龄获取失败!" + fmt.Sprint(e))
	}
	sex, e1 := this.GetBool("sex")

	if e1 != nil {
		this.Ctx.WriteString("获取性别失败！")
	}
	var user = models.User{Name:name, NickName:nickname, Password:password, Age:age, Sex:sex}
	orm := orm.NewOrm()

	_, i2 := orm.Insert(&user)
	if i2 != nil {

		this.Ctx.WriteString("插入失败！" + fmt.Sprint(i2))
	} else {

		this.Ctx.WriteString("插入成功!")
	}

}

注册路由

	//注册
	beego.Router("/registe",&controllers.Demo4Controlle{})

用户访问时，获得这个页面，这个页面默认存放在view模块下

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>register</title>
</head>
<body>

<form action="registe" method="post">
<form>
    <table>
        <thead>注册</thead>
        <tbody>
        <tr>
            <td>
            <label for="name">姓名:</label>
            <input type="text" name="name" id="name">
            </td>
        </tr>
        <tr>
            <td>
                <label for ="nickname">昵称:</label>
                <input type="text" name = "nickname" id="nickname">
            </td>
        </tr>
        <tr>
            <td>
                <label for = "password">密码:</label>
                <input type="password" name = "password" id="password">
            </td>
        </tr>
        <tr>
            <td>
                <label for = "age">年龄:</label>
                <input type="text" name = "age" id="age">
            </td>
        </tr>


        <tr>
            <td>
                <label for = "man">男:</label>
                <input type="radio" id="man" value="true" name="sex" >
                <label for = "women">女:</label>
                <input type="radio" id="women" name ="sex" value="false" >
            </td>
        </tr>
        <tr>
            <td>
               <input type="submit" value="提交">
                <input type="reset" value="重置">
            </td>
        </tr>
        </tbody>
    </table>
</form>
</form>

</body>
</html>

在model中新建一个文件，`form:"name"`这个是表明表格中的关键字是name对应着结构体中Name，也可以在html文件中将关键字定义为Name，这样就不用声明了。

package models

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

type User struct {
	Id int
	Name     string `form:"name"`
	NickName string`form:"nickname"`
	Password string`form:"password"`
	Age      int`form:"age"`
	Sex      bool`form:"sex"`
}

func init(){

	db_name:=beego.AppConfig.String("db_name")
	db_user := beego.AppConfig.String("db_user")
	db_password := beego.AppConfig.String("db_password")
	db_host := beego.AppConfig.String("db_host")
	db_port := beego.AppConfig.String("db_port")

//root:123456@tcp(localhost:3306)/user?charset=utf8
	url:=db_user+":"+db_password+"@tcp("+db_host+":"+db_port+")/"+db_name+"?charset=utf8"

	orm.RegisterDataBase("default","mysql",url,30)

	orm.RegisterModel(new(User))

	orm.RunSyncdb("default",true,true)


}
