mongoDB中mongoose的位置 [英] Location in mongoose, mongoDB

问题描述

每当我尝试将位置存储在mongodb中时，它都不会显示，所以我想我做错了什么. 我找不到任何有关如何在猫鼬中存储位置的文档，所以我只想在这里询问.

Whenever I try to store a location in my mongodb it doesn't show, so I guess I'm doing something wrong. I can't find any documentation on how to store a location in mongoose so I'm just gonna ask it here.

我首先创建我的模型:

var eventSchema = mongoose.Schema({ 
    name : String,
    creator : String,
    location : { type: [Number], index: '2dsphere'},

});

然后我尝试将其添加到我的数据库中:

Then I try to add it to my database:

var newevent = new event({ 
        name: name,
        creator: tokenUser, 
        location : { type: "Point", coordinates: [longitude, latitude] },
});

当我查看数据库时，除了位置以外，所有内容都存储了...

When I look in my database everything is stored except the location ...

推荐答案

我自己修复了该问题.

我在模型中做到了这一点

I did this in my model:

loc :  { type: {type:String}, coordinates: [Number]},

在下面，我将其设为2dsphere索引.

Underneath I made it a 2dsphere index.

eventSchema.index({loc: '2dsphere'});

并向其中添加数据:

loc: { type: "Point", coordinates: [ longitude, latitude ] },
