无法提取地理密钥，未知的 GeoJSON 类型：{ 坐标：[ 13.42493130000003, 52.50074619999999 ]

Question

我有这个表单，我可以在其中获取用户的信息，该用户已正确保存了位置。

\n\n

但是当我尝试更新它时，它给了我这个错误：

\n\n

我的用户拥有我认为需要的所有东西：

\n\n

const userSchema = new Schema({\n  email: {\n    type: String,\n    unique: true,\n    lowercase: true,\n    trim: true,\n    validate: [validator.isEmail, \'Invalid Email Address\'],\n    required: \'Please Supply an email address\'\n  },\n  name: {\n    type: String,\n    required: \'Please supply a name\',\n    trim: true\n  },\n  resetPasswordToken: String,\n  resetPasswordExpires: Date,\n  props: [\n    { type: mongoose.Schema.ObjectId, ref: \'User\' }\n  ],\n  // New stuff\n  slug: String,\n  genres: [String],\n  musicLink: String,\n  created: {\n    type: Date,\n    default: Date.now\n  },\n  location: {\n    type: {\n      type: String,\n      default: \'Point\'\n    },\n    coordinates: [{\n      type: Number,\n      required: \'You must supply coordinates!\'\n    }],\n    address: {\n      type: String,\n      required: \'You must supply an address!\'\n    }\n  },\n  photo: String,\n});\n\nuserSchema.index({ location: \'2dsphere\' })\n

\n\n

当我保存它时，有一个控制器只推送某些内容来更新用户：

\n\n

exports.updateAccount = async (req, res) => {\n  const updates = {\n    name: req.body.name,\n    email: req.body.email,\n    musicLink: req.body.musicLink,\n    genres: req.body.tags,\n    location: {\n      address: req.body.location.address,\n      coordinates: [\n        req.body.location.coordinates[0],\n        req.body.location.coordinates[1],\n      ]\n    }\n  };\n\n  console.log(\'coordinates: \', updates.location.coordinates)\n\n  const user = await User.findOneAndUpdate(\n    { _id: req.user._id },\n    { $set: updates },\n    { new: true, runValidators: true, context: \'query\' }\n  );\n  req.flash(\'success\', \'Updated the profile!\');\n  res.redirect(\'back\');\n};\n

\n\n

知道可能是什么问题吗？

谢谢。

Answer 1

正如Mongoose 文档（以及GeoJSON 格式的基础标准）中所指定的，几何对象必须包含一个“几何类型”，其值为以下之一

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 ]}
