xorm自動產生model檔案

如果沒有go- sql-driver/mysql就先安裝

go get -u github.com/go-sql-driver/mysql

安裝xorm，在cmd命令列下

go get github.com/go-xorm/xorm

再安裝xorm的cmd命令工具

go get github.com/go-xorm/cmd/xorm

安裝cmd 報錯處理

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

跳出專案目錄執行，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 %

在專案目錄下建立templates/goxorm 資料夾

• 這個檔案下建立config和struct.go.tpl檔案.
• 範本內容可以根據你自己的需求修改
• config內容如下

  lang=go
  genJson=1prefix=

• struct.go.tpl內容如下

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}}

• #最後執行指令

  程式會在目前目錄下產生models資料夾，並在models資料夾中產生go檔

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

#執行錯誤

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

• 解決方案

  vim ~/.zshrc

• #在~/.zshrc中加入:

  setopt no_nomatch

• 檢查一下

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

• 最後執行

  source ~/.zshrc

再次執行

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

剩下就是把models裡的內容賦值到model 對應的model裡面了
