这是我讨厌的问题.我的models/model.go

Here is my noobish problem. I have this struct in my models/model.go

package models import ( "time" "gopkg.in/mgo.v2/bson" ) type Horse struct { Id bson.ObjectId `bson:"_id,omitempty"` Title string Description string CreatedOn time.Time Creator string Visits int Score int }

在我的controllers/crud.go中，我正在尝试使用Horse结构

And in my controllers/crud.go I'm trying to use Horse struct

package controllers import ( "html/template" "log" "net/http" "horseapp/models" ) [...] var horseStore = make(map[string]Horse) //This raises undefined error

但是当我go install horseapp时我得到了undefined: Horse.

这是怎么了?如何解决?

What is wrong here and how to fix it?

推荐答案

使用

var horseStore = make(map[string]models.Horse)

从另一个包访问标识符时，必须始终在包名前加上一个包名和一个点:package.Identifier

When accessing an identifier from another package you will always have to prefix it with the packages name and a dot: package.Identifier
