README

Laravel package to work with spatial data types and functions.

This package supports MySQL 5.7 & 8.0 and works on PHP 8 & Laravel 8.

Installation

You can install the package via composer:

composer require matanyadaev/laravel-eloquent-spatial

Quickstart

Generate a new model with a migration file:

php artisan make:model {modelName} --migration

Add some spatial columns to the migration file:

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

class CreatePlacesTable extends Migration
{
    public function up(): void
    {
        Schema::create('places', static function (Blueprint $table) {
            $table->id();
            $table->string('name')->unique();
            $table->point('location')->nullable();
            $table->polygon('area')->nullable();
            $table->timestamps();
        });
    }

    public function down(): void
    {
        Schema::dropIfExists('places');
    }
}

Run the migration:

php artisan migrate

Fill the $fillable and $casts arrays and add custom eloquent builder to your new model:

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use MatanYadaev\EloquentSpatial\SpatialBuilder;
use MatanYadaev\EloquentSpatial\Objects\Point;
use MatanYadaev\EloquentSpatial\Objects\Polygon;

/**
 * @property Point $location
 * @property Polygon $area
 * @method static SpatialBuilder query()
 */
class Place extends Model
{
    protected $fillable = [
        'name',
        'location',
        'area',
    ];

    protected $casts = [
        'location' => Point::class,
        'area' => Polygon::class,
    ];
    
    public function newEloquentBuilder($query): SpatialBuilder
    {
        return new SpatialBuilder($query);
    }
}

Access spatial data:

use App\Models\Place;
use MatanYadaev\EloquentSpatial\Objects\Polygon;
use MatanYadaev\EloquentSpatial\Objects\LineString;
use MatanYadaev\EloquentSpatial\Objects\Point;

$londonEye = Place::create([
    'name' => 'London Eye',
    'location' => new Point(51.5032973, -0.1195537)
]);

$vaticanCity = Place::create([
    'name' => 'Vatican City',
    'area' => new Polygon([
        new LineString([
              new Point(12.455363273620605, 41.90746728266806),
              new Point(12.450309991836548, 41.906636872349075),
              new Point(12.445632219314575, 41.90197359839437),
              new Point(12.447413206100464, 41.90027269624499),
              new Point(12.457906007766724, 41.90000118654431),
              new Point(12.458517551422117, 41.90281205461268),
              new Point(12.457584142684937, 41.903107507989986),
              new Point(12.457734346389769, 41.905918239316286),
              new Point(12.45572805404663, 41.90637337450963),
              new Point(12.455363273620605, 41.90746728266806),
        ])
    ])
])

Retrieve a record with spatial data:

echo $londonEye->location->latitude; // 51.5032973
echo $londonEye->location->longitude; // -0.1195537

echo $vacationCity->area->toJson(); // {"type":"Polygon","coordinates":[[[41.90746728266806,12.455363273620605],[41.906636872349075,12.450309991836548],[41.90197359839437,12.445632219314575],[41.90027269624499,12.447413206100464],[41.90000118654431,12.457906007766724],[41.90281205461268,12.458517551422117],[41.903107507989986,12.457584142684937],[41.905918239316286,12.457734346389769],[41.90637337450963,12.45572805404663],[41.90746728266806,12.455363273620605]]]}

API

Tip for better IDE support

In order to get better IDE support, you should add a query method phpDoc annotation to your model:

/**
 * @method static SpatialBuilder query()
 */
class Place extends Model
{
    // ...
}

Or alternatively override the method:

class Place extends Model
{
    public static function query(): SpatialBuilder
    {
        return parent::query();
    }
}

Create queries only with the query() static method:

Place::query()->whereDistance(...); // This is IDE-friendly
Place::whereDistance(...); // This is not

Tests

composer phpunit
# or with coverage
composer phpunit-coverage
