It seems like Sailsjs/Waterline does not currently support a POINT type or geospatial indexing with JSON.
Are there any ways to customize a schema for certain adapters to support geospatial datatypes?
If not, is there a way to integrate a second ORM into Waterline that does so?
回答1:
In Sails.js, you need MongoDB (npm install --save sails-mongo) for geospatial indexing, plus you need to ensure the 2dindex gets created in config/bootstrap.js as such (make sure to replace modelname and attributename for your particular needs):
module.exports.bootstrap = function(cb) {
// Ensure we have 2dsphere index on coordinates attribute of Place.
sails.models.modelname.native(function (err, collection) {
collection.ensureIndex({ attributename: '2dsphere' }, function () {
// It's very important to trigger this callback method when you are finished
// with the bootstrap! (otherwise your server will never lift, since it's waiting on the bootstrap)
cb();
});
});
};Also note that you have to use native MongoDB geospatial queries, which is beyond the scope of your question. I've posted an example implementation here

If you check the waterline documentation you can see how to create custom data types and your own validation, you can find a geospatial example here
