5. 编写迁移代码
5.1 添加对应的方法
文件：model/migrate/migrate.go
func setTableOption(tableComment string) *gorm.DB {
value := fmt.Sprintf("ENGINE=InnoDB COMMENT='%s'", tableComment)
return global.GvaMysqlClient.Set("gorm:table_options", value)
}
func userMigrate() {
_ = setTableOption("用户表").AutoMigrate(&entity.User{})
_ = setTableOption("用户信息表").AutoMigrate(&entity.UserInfo{})
}
func fundMigrate() {
_ = setTableOption("基金表").AutoMigrate(&entity.FundBasis{})
_ = setTableOption("基金持仓表").AutoMigrate(&entity.FundStock{})
_ = setTableOption("基金每日排行").AutoMigrate(&entity.FundDayTop{})
}
func stockMigrate() {
_ = setTableOption("股票表").AutoMigrate(&entity.Stock{})
_ = setTableOption("股票行情表").AutoMigrate(&entity.StockQuotes{})
}
|
5.2 修改迁移入口函数
文件：model/migrate/migrate.go
func AutoMigrate() {
userMigrate()
fundMigrate()
stockMigrate()
}
|
6. 启动项目
6.1 修改配置
文件：./config.yaml
...
mysql:
enable: true
....
database: fund_analye_system
autoMigrate: true
...
gorm:
tablePrefix: "fas_"
...
|
6.2 自动创建表
当在配置中,打开autoMigrate=true时，成功启动项目后，会创建以下表信息。
