node.js - Mongoose 选择 : false not working on location nested object

Question

我希望我的架构的 location 字段默认隐藏。我添加了 select: false 属性，但是选择文档时总是返回它...

var userSchema = new mongoose.Schema({

cellphone: {
  type: String,
  required: true,
  unique: true,
},

location: {
  'type': {
    type: String,
    required: true,
    enum: ['Point', 'LineString', 'Polygon'],
    default: 'Point'
   },
   coordinates: [Number],
   select: false, <-- here
   },
});

userSchema.index({location: '2dsphere'});

调用时:

User.find({ }, function(err, result){
控制台.log(结果[0]);
});

输出是:

 {  
    cellphone: '+33656565656',
    location: { type: 'Point', coordinates: [Object] } <-- Shouldn't
 }

编辑:解释(感谢@alexmac)

SchemaType 选择选项必须应用于字段选项而不是类型。在您的示例中，您已经定义了一个复杂类型 Location 并向类型添加了选择选项。

您应该首先创建 locationSchema，然后使用带有 select: false 的模式类型:

var locationSchema = new mongoose.Schema({
    'type': {
        type: String,
        required: true,
        enum: ['Point', 'LineString', 'Polygon'],
        default: 'Point'
       },
       coordinates: [Number]
    }
});

var userSchema = new mongoose.Schema({
    location: {
      type: locationSchema,
      select: false
    }
});
