【问题描述】：

我有这个表格，我可以在其中获取用户的信息，用户已正确保存了位置。

但是当我尝试更新它时，它又给了我这个错误：

我的用户拥有我认为需要的所有东西：

const userSchema = new Schema({
  email: {
    type: String,
    unique: true,
    lowercase: true,
    trim: true,
    validate: [validator.isEmail, 'Invalid Email Address'],
    required: 'Please Supply an email address'
  },
  name: {
    type: String,
    required: 'Please supply a name',
    trim: true
  },
  resetPasswordToken: String,
  resetPasswordExpires: Date,
  props: [
    { type: mongoose.Schema.ObjectId, ref: 'User' }
  ],
  // New stuff
  slug: String,
  genres: [String],
  musicLink: String,
  created: {
    type: Date,
    default: Date.now
  },
  location: {
    type: {
      type: String,
      default: 'Point'
    },
    coordinates: [{
      type: Number,
      required: 'You must supply coordinates!'
    }],
    address: {
      type: String,
      required: 'You must supply an address!'
    }
  },
  photo: String,
});

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

当我保存它时，有一个控制器只推送某些内容来更新用户：

exports.updateAccount = async (req, res) => {
  const updates = {
    name: req.body.name,
    email: req.body.email,
    musicLink: req.body.musicLink,
    genres: req.body.tags,
    location: {
      address: req.body.location.address,
      coordinates: [
        req.body.location.coordinates[0],
        req.body.location.coordinates[1],
      ]
    }
  };

  console.log('coordinates: ', updates.location.coordinates)

  const user = await User.findOneAndUpdate(
    { _id: req.user._id },
    { $set: updates },
    { new: true, runValidators: true, context: 'query' }
  );
  req.flash('success', 'Updated the profile!');
  res.redirect('back');
};

知道可能是什么问题吗？

谢谢。

【问题讨论】：

您需要在对象中有“类型”。例如。 {type: "point", coordinates: [...]}仅供参考mongoosejs.com/docs/geojson.html
谢谢，这实际上是问题所在。如果您将其添加为答案，则将其标记为正确的答案。谢谢！

标签： mongodb mongoose geojson mongoose-schema

【解决方案1】：

如Mongoose docs（以及GeoJSON 格式的underlying standard）中所指定，几何对象必须包含值为以下之一的“几何类型”

七个区分大小写的字符串：“Point”、“MultiPoint”、“LineString”、 “MultiLineString”、“Polygon”、“MultiPolygon”和“GeometryCollection”

错误信息

unknown GeoJSON type: { coordinates: [13.42493130000003, 52.50074619999999 ]

指对象中缺少的类型属性。包括type 以避免错误：

{type: "Point", coordinates: [13.42493130000003, 52.50074619999999 ]}
