Encode / parse wkt

[tomaszantas]

How can I parse / encode wkt?

I've got simple model of Places:

class CreatePlaces < ActiveRecord::Migration[5.1]
  def change

    create_table :places do |t|
      t.string :name
      t.st_point :coords, :geographic => true

      t.timestamps
    end

    change_table :places do |t|
      t.index :coords, using: :gist
    end

  end
end

I get all places in following way:

class PlacesController < ApplicationController

  def index
    @places = Place.all

    render json: @places.to_json
  end

end

But my JSON in response contains WKT:

[
    {
        "id": 1,
        "name": "test name 1",
        "coords": "POINT (50.324192 19.037805)",
        "created_at": "2017-09-07T20:29:19.203Z",
        "updated_at": "2017-09-07T20:29:19.203Z"
    }
]

I can map @places and encode coords like this:

class PlacesController < ApplicationController

  def index
    @places = Place.all

    @places.map { |k,v| k.coords = RGeo::GeoJSON.encode(k.coords, json_parser: :json) }

    render json: @places.to_json
  end

end

And then I get what I wanted - encoded/parsed coords:

[
    {
        "id": 1,
        "name": "test name 1",
        "coords": {
            "type": "Point",
            "coordinates": [
                50.324192,
                19.037805
            ]
        },
        "created_at": "2017-09-07T20:29:19.203Z",
        "updated_at": "2017-09-07T20:29:19.203Z"
    }
]

Is it right way to encode POINT?
