Laravel Eloquent Spatial

This Laravel package allows you to easily work with spatial data types and functions.

The latest version, v3, supports Laravel 10 and PHP 8.1+. For Laravel 8 or 9, and PHP 8.0, use v2.

This package supports MySQL v8, MySQL v5.7, and MariaDB v10.

Getting Started

Installing the Package

You can install the package via composer:

composer require matanyadaev/laravel-eloquent-spatial

Setting Up Your First Model

First, generate a new model along with a migration file by running:
```
php artisan make:model {modelName} --migration
```

Next, add some spatial columns to the migration file. For instance, to create a "places" table:

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
```

In your new model, fill the $fillable and $casts arrays and use the HasSpatial trait:

namespace App\Models;

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

/**
 * @property Point $location
 * @property Polygon $area
 * @method static SpatialBuilder query()
 */
class Place extends Model
{
    use HasSpatial;

    protected $fillable = [
        'name',
        'location',
        'area',
    ];

    protected $casts = [
        'location' => Point::class,
        'area' => Polygon::class,
    ];
}

Interacting with Spatial Data

After setting up your model, you can now create and access spatial data. Here's an example:

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

// Create new records

$londonEye = Place::create([
    'name' => 'London Eye',
    'location' => new Point(51.5032973, -0.1217424),
]);

$whiteHouse = Place::create([
    'name' => 'White House',
    'location' => new Point(38.8976763, -77.0365298, Srid::WGS84->value), // with SRID
]);

$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),
        ]),
    ]),
])

// Access the data

echo $londonEye->location->latitude; // 51.5032973
echo $londonEye->location->longitude; // -0.1217424

echo $whiteHouse->location->srid; // 4326

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]]]}

Tips for Improving IDE Support

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

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

Or you could 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

Extension

You can add new methods to the Geometry class through macros.

Here's an example of how to register a macro in your service provider's boot method:

class AppServiceProvider extends ServiceProvider
{
    public function boot(): void
    {
        Geometry::macro('getName', function (): string {
            /** @var Geometry $this */
            return class_basename($this);
        });
    }
}

Use the method in your code:

$londonEyePoint = new Point(51.5032973, -0.1217424);

echo $londonEyePoint->getName(); // Point
