Detailed explanation of how xorm automatically generates models

This article is written by the go language tutorial column to introduce to you the method of automatically generating mode by xorm. I hope it will be helpful to friends in need!

xorm automatically generates model files

Enter the project root directory

luwei@luweideMacBook-Pro-2 go-simple-task % pwd/Users/myself/Golang/common_project/src/go-simple-task

If there is no go- sql-driver/mysql first install

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

Install xorm, under the cmd command line

go get github.com/go-xorm/xorm

then install the xorm cmd command tool

go get github.com/go-xorm/cmd/xorm

Installation cmd error handling

Jump out of the project directory to execute, then jump back when finished

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 %

Create in the project directory templates/goxorm folder

• Create config and struct.go.tpl files under this file.
• The template content can be modified according to your own needs
• config content The content of

  lang=go
  genJson=1prefix=

• struct.go.tpl is as follows

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}}

• Finally execute the command

  The program will generate the models folder in the current directory and Generate go files in the models folder

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

Execution error

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

• Solution

  vim ~/.zshrc

• Add to ~/.zshrc:

  setopt no_nomatch

• Check

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

• Finally execute

  source ~/.zshrc

##Execute again

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

The rest is to assign the content in models to the corresponding model
