xorm自動生成model檔案

進入專案根目錄

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

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

    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.
  • 模板內容可以根據你自己的需要修改
  • config內容如下
    lang=go
genJson=1
prefix=
  • 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}}
  • 最後執行命令

    程式會在當前目錄下生成models資料夾，並在models資料夾中生成go檔案

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

執行報錯

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_profile
export 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 %

xorm自動生成model

剩下就是把models裡的內容賦值到model 對應的model裡面了
