Mongoose Schema for geoJson coordinates

Question

I tried to create a schema for geojson but have had some problems with syntax for coordinates.

Here\'s my current code:

var DataSchema = new Schema({
           


        

Answer 1

Like this;

var DataSchema = new Schema({
  properties: {
    title:       { type: String, required: true },
    description: { type: String, required: true },
    date:        { type:Date, default:Date.now }
  },
  geometry: {
    coordinates: { type: [Number], index: '2dsphere'}
  }
});

Here is your update route handler, it converts coordinates string to number array;

app.post('/mountain_rescue',  function (req, res) {
  new rescueData({
    properties: {
      title: req.body.title, description: req.body.description
    },
    geometry: {
      coordinates:req.body.coordinates.split(',').map(Number)
    }
  }).save(function (e, result) {
    console.log(result);
  });
  res.redirect('/mountain_rescue');
});

A GeoJSON field has to be included a geometry type as a string. So a GeoJSON field must be defined like the following;

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

or if you want to define a default value you might use the below line;

geometry: { type: { type: String, default:'Point' }, coordinates: [Number] }

Good luck..

try this:

var DataSchema = new Schema({
  properties: {
    title:       { type: String, required: true },
    description: { type: String, required: true },
    date:        { type:Date, default:Date.now }
  },
  geometry: {
       coordinates: {type: Array, required: true}
  }
});
