The problem of inputting uncertain parameters into go

< H1 > question < / H1 >

when registering models using the beego framework, an error is reported:

panic: <orm.RegisterModel> cannot use non-ptr model struct `.`

if you look at the description, you should pass in the pointer, but I passed the pointer (new)

.

main.go

package db

import (
    "github.com/astaxie/beego/orm"
)

func InitDB(models ...interface{}) {
    orm.RegisterDriver("mysql", orm.DRMySQL)
    // set default database
    orm.RegisterDataBase("default", "mysql", "root:*****@tcp(127.0.0.1:3306)/db_test?charset=utf8", 30)
    // register model
    orm.RegisterModel(models)
    // create table
    orm.RunSyncdb("default", false, true)
}

db/main.go

package db

import (
    "github.com/astaxie/beego/orm"
)

func InitDB(models ...interface{}) {
    orm.RegisterDriver("mysql", orm.DRMySQL)
    // set default database
    orm.RegisterDataBase("default", "mysql", "root:123456@tcp(127.0.0.1:3306)/db_test?charset=utf8", 30)
    // register model
    orm.RegisterModel(models)
    // create table
    orm.RunSyncdb("default", false, true)
}

models/user.go

package models

import "hello/db"

type User struct {
    Uid      int `orm:"pk"`
    Username string
    Password string
}
The InitDB function in

db/main.go registers models, and then reports an error

The parameter of

models .interface {} syntax should be [] interface {}
after it is received, so it should be orm.RegisterModel (models.) when passed to RegisterModel as is. Write
