现在到控制器中看看我们怎么调用模型的方法的实现（增、删、改、查）项目/controllers/test.go
package controllers
import (
"fmt"
"github.com/astaxie/beego"
"github.com/astaxie/beego/orm"
"strconv"
"test/models"
)
type TestController struct {
beego.Controller
}
var arc models.Archives
func (this *TestController) Show() {
data, err := arc.Show()
fmt.Println(data, err)
}
func (this *TestController) Add() {
title := "测试标题"
body := "测试内容"
typeid := 1
id, err := arc.Add(title, body, typeid)
fmt.Println(id, err)
}
func (this *TestController) Edit() {
title := "测试标题"
body := "测试内容"
typeid := 1
id := 1
err := arc.Edit(title, body, typeid, id)
fmt.Println(err)
}
func (this *TestController) Delete() {
id := 1
err := arc.Delete(id)
fmt.Println(err)
}
go的结构很灵活，beego的框架很简单，只要是略懂MVC就行了，关键部分在GO的基础
