[golang] implicit assignment of unexported field
struct结构如下：package models
import (
"github.com/robfig/revel"
)
type Post
struct {
id
int
title
string
}
我在另一个包里面使用
package controllers
import (
"blog/app/models"
"fmt"
"github.com/coopernurse/gorp"
"github.com/robfig/revel"
)
type Application struct {
*revel.Controller
Txn *gorp.Transaction
}
func (c Application) Index() revel.Result {
post := &models.Post{1, "title"}
fmt.Println(post)
return c.Render()
}
会出现如下错误：
implicit assignment of unexported field
原因是，struct定义的属性是小写开头的，不是public的，这样是不能跨包调用的！
正确的写法应该是
type Post struct {
Id
int
Title
string
}
属性大写开关
Have fun with golang!
