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-task
luwei@luweideMacBook-Pro-2 go-simple-task % ls
Dockerfile      go-simple-task  go.mod          go.sum          logic           logs            main.go         model           models          overall         serv            templates       tool
luwei@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

绘蛙

下载

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

安装 cmd 报错处理

luwei@luweideMacBook-Pro-2 go-simple-task % go get github.com/go-xorm/cmd/xorm
# github.com/go-xorm/cmd/xorm
../../pkg/mod/github.com/go-xorm/cmd/xorm@v0.0.0-20190426080617-f87981e709a1/dump.go:45:26: cannot use "github.com/go-xorm/core".LOG_UNKNOWN (type "github.com/go-xorm/core".LogLevel) as type "xorm.io/core".LogLevel in argument to engine.Logger().SetLevel

luwei@luweideMacBook-Pro-2 go-simple-task %

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/xorm
luwei@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=go
genJson=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/goxorm
zsh: 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,direct
setopt 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/goxorm
luwei@luweideMacBook-Pro-2 go-simple-task %
