从其他包导入的结构未定义 [英] Imported struct from other package is undefined

问题描述

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
