详解xorm怎么自动生成model

xorm自动生成model文件

进入项目根目录

luwei@luweideMacBook-PRo-2 go-simple-task % pwd/Users/myself/Golang/common_project/src/go-simple-taskluwei@luweideMacBook-Pro-2 go-simple-task % lsdockerfile      go-simple-task  go.mod          go.sum          LOGic           logs            main.go         model           models          overall         serv            templates       toolluwei@luweideMacBook-Pro-2 go-simple-task %

如果没有go-SQL-driver/MySQL就先安装

go get -u gIThub.COM/go-sql-driver/mysql

安装xorm，在cmd命令行下

go get github.com/go-xorm/xorm

再安装xorm的cmd命令工具

go get github.com/go-xorm/cmd/xorm

安装 cmd 报错处理

跳出项目目录执行，完了再跳回去

luwei@luweideMacBook-Pro-2 go-simple-task % cd ../luwei@luweideMacBook-Pro-2 src % go get github.com/go-xorm/cmd/xormluwei@luweideMacBook-Pro-2 src %

在项目目录下建立 templates/goxorm 文件夹

• 这个文件下建立config和struct.go.tpl文件.
• 模板内容可以根据你自己的需要修改
• config内容如下

  lang=gogenJson=1prefix=

• struct.go.tpl内容如下

package {
{
.Models}
}
{
{
$ilen := len .Imports}
}
{
{
if gt $ilen 0}
}
import (    {
{
range .Imports}
}
"{
{
.}
}
"{
{
end}
}
){
{
end}
}
{
{
range .Tables}
}
type {
{
Mapper .Name}
}
 struct {
{
{
$table := .}
}
{
{
range .ColumnsSeq}
}
{
{
$col := $table.GetColumn .}
}
 {
{
Mapper $col.Name}
}
    {
{
Type $col}
}
 {
{
Tag $table $col}
}
{
{
end}
}
}
{
{
end}
}
    

• 最后执行命令

  程序会在当前目录下生成models文件夹，并在models文件夹中生成go文件

  xorm reverse mysql root:root@/fox?charset=utf8 templates/goxorm

执行报错

luwei@luweideMacBook-Pro-2 go-simple-task % xorm reverse mysql root:123456@/bubble?charset=utf8 templates/goxormzsh: no matches found: root:123456@/bubble?charset=utf8

• 解决方案

  vim ~/.zshrc

• 在~/.zshrc中加入:

  setopt no_nomatch

• 检查一下

  luwei@luweideMacBook-Pro-2 go-simple-task % cat ~/.zshrc                                              source ~/.bash_profileexport GOProxy=https://goproxy.io,directsetopt no_nomatch

• 最后执行

  source ~/.zshrc

再次执行

luwei@luweideMacBook-Pro-2 go-simple-task % xorm reverse mysql root:123456@/bubble?charset=utf8 templates/goxormluwei@luweideMacBook-Pro-2 go-simple-task %

剩下就是把models里的内容赋值到model 对应的model里面了
