话不多说直接上代码‘

定义要连接的数据库 main.go

package  main
import  (
  _  "newgo/routers"
  "github.com/astaxie/beego"
  "github.com/astaxie/beego/orm"
  _  "github.com/go-sql-driver/mysql"
)
func  init()  {
  orm.RegisterDriver("mysql",  orm.DRMySQL)
  orm.RegisterDataBase("default",  "mysql",  "root:root@tcp(127.0.0.1:3306)/go?charset=utf8")
}
func  main()  {
  beego.Run()
}

定义路由 router.go

beego.Router("/type", &controllers.ClassifyController{}, "GET:Type")
beego.Router("/classifyinsert", &controllers.ClassifyController{}, "POST:ClassifyInsert")
beego.Router("/classifyupdate", &controllers.ClassifyController{}, "GET:ClassifyUpdate")
beego.Router("/classifysave", &controllers.ClassifyController{}, "POST:ClassifySave")
beego.Router("/classifydel", &controllers.ClassifyController{}, "GET:ClassifyDel")

model书写

package  models
import  (
  "github.com/astaxie/beego/orm"
)
type  Classify  struct  {
  Id  int
  Name  string
  Content  string
}
func  init()  {
  orm.RegisterModel(new(Classify))
}
//增加操作
func  InsertClassify(name  string,  content  string)  (int64,  error)  {
  o  :=  orm.NewOrm()
  var  clasinfo  Classify
  clasinfo.Name  =  name
  clasinfo.Content  =  content
  id,  err  :=  o.Insert(&clasinfo)
  return  id,  err
}
//删除操作
func  ClassifyDel(id  int)  ([]Classify,  int64,  error)  {
  o  :=  orm.NewOrm()
  var  lists  []Classify
  num,  err  :=  o.QueryTable("classify").Filter("Id",  id).Delete()
  o.QueryTable("inventory").Filter("Cid",  id).Delete()
  return  lists,  num,  err
}
//展示
func  ClassifyList()  ([]Classify,  int64,  error)  {
  o  :=  orm.NewOrm()
  var  lists  []Classify
  num,  err  :=  o.QueryTable("classify").All(&lists)
  return  lists,  num,  err
}
//修改
func  ClassifyUpdate(id  int,  name  string,  content  string)  ([]Classify,  int64,  error)  {
  o  :=  orm.NewOrm()
  var  lists  []Classify
  num,  err  :=  o.QueryTable("classify").Filter("Id",  id).Update(orm.Params{
  "name":  name,
  "content":  content,
  })
  return  lists,  num,  err
}

控制器

package  controllers
import  (
  "fmt"
  "newgo/models"
  "strings"
  "github.com/astaxie/beego/orm"
  "github.com/astaxie/beego"
)
type  ClassifyController  struct  {
  beego.Controller
}
func  (c  *ClassifyController)  Get()  {
  c.TplName  =  "index.html"
}
func  (c  *ClassifyController)  Type()  {
  list,  num,  err  :=  models.ClassifyList()
  if  err  ==  nil  {
  fmt.Println(list)
  fmt.Println(num)
  }
  c.Data["comment"]  =  list
  fmt.Println(list)
  c.TplName  =  "type.html"
}
//添加post
func  (c  *ClassifyController)  ClassifyInsert()  {
  content  :=  strings.TrimSpace(c.GetString("content"))
  name  :=  strings.TrimSpace(c.GetString("name"))
  models.InsertClassify(name,  content)
  c.Ctx.Redirect(302,  "/type")
}
//修改get展示
func  (c  *ClassifyController)  ClassifySave()  {
  id,  _  :=  c.GetInt("id")
  fmt.Println(id)
  content  :=  strings.TrimSpace(c.GetString("content"))
  name  :=  strings.TrimSpace(c.GetString("name"))
  models.ClassifyUpdate(id,  name,  content)
  c.Ctx.Redirect(302,  "/type")
}
//删除
func  (c  *ClassifyController)  ClassifyDel()  {
  id,  _  :=  c.GetInt("id")
  models.ClassifyDel(id)
  c.Ctx.WriteString("200")
}
//修改post方法
func  (c  *ClassifyController)  ClassifyUpdate()  {
  id,  _  :=  c.GetInt("id")
  o  :=  orm.NewOrm()
  type  Comment  struct  {
  Id  int
  Name  string
  Content  string
  }
  var  comments  []Comment
  var  com  []Comment
  num,  err  :=  o.Raw("select  *  from  classify  where  id=?",  id).QueryRows(&comments)
  o.Raw("select  *  from  classify").QueryRows(&com)
  if  err  ==  nil  {
  fmt.Println(num)
  fmt.Println(comments)
  fmt.Println(com)
  c.Data["updates"]  =  comments
  c.Data["comment"]  =  com
  }  else  {
  fmt.Println("查询报错")
  }
  c.TplName  =  "type.html"
}
