mammutgroup/laravel-spatial

Laravel Mysql Geometry extension

Features

• Work with geometry classes instead of arrays. ($myModel->myPoint = new Point(1,2))
• Adds helpers in migrations. ($table->polygon('myColumn'))

Future plans

• Geometry functions on the geometry classes (contains(), equals(), distance(), etc… (HELP!))

Versions

Use 2.* for Laravel 5.1.*
Use 3.* for Laravel 5.2.*

Installation

composer require phaza/laravel-postgis 

Next add the DatabaseServiceProvider to your config/app.php file.

'Mammutgroup\LaravelPostgis\DatabaseServiceProvider',

That's all.

Usage

First of all, make sure to enable postgis.

CREATE EXTENSION postgis;

To verify that postgis is enabled

SELECT postgis_full_version();

Migrations

Now create a model with a migration by running

php artisan make:model Location

If you don't want a model and just a migration run

php artisan make:migration create_locations_table

Open the created migrations with your editor.

use Illuminate\Database\Migrations\Migration;
use Mammutgroup\LaravelPostgis\Schema\Blueprint;

class CreateLocationsTable extends Migration {

    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('locations', function(Blueprint $table)
        {
            $table->increments('id');
            $table->string('name');
            $table->string('address')->unique();
            $table->point('location');
            $table->polygon('polygon');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::drop('locations');
    }

}

Available blueprint geometries:

• point
• multipoint
• linestring
• multilinestring
• polygon
• multipolygon
• geometrycollection

other methods:

• enablePostgis
• disablePostgis

Models

All models which are to be PostGis enabled must use the PostgisTrait.

You must also define an array called $postgisFields which defines what attributes/columns on your model are to be considered geometry objects.

use Illuminate\Database\Eloquent\Model;
use Mammutgroup\LaravelPostgis\Eloquent\PostgisTrait;
use Mammutgroup\LaravelPostgis\Geometries\Point;

class Location extends Model
{
    use PostgisTrait;

    protected $fillable = [
        'name',
        'address'
    ];

    protected $postgisFields = [
        'location',
        'polygon',
    ];

}

$location1 = new Location();
$location1->name = 'Googleplex';
$location1->address = '1600 Amphitheatre Pkwy Mountain View, CA 94043';
$location1->location = new Point(37.422009, -122.084047);
$location1->save();

$location2 = Location::first();
$location2->location instanceof Point // true

Available geometry classes:

• Point
• MultiPoint
• LineString
• MultiLineString
• Polygon
• MultiPolygon
• GeometryCollection
