composer require lscortesc/laravel-postgis

包简介

Postgis extensions for laravel. Aims to make it easy to work with geometries from laravel models

README 文档

README

Build Status

Features

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

Warning

This Package has been moved to a new owner and aims for Laravel 6/7/8 and PHP 7 support only soon!

Replace all your references to the new namespace:

MStaack\LaravelPostgis

Thanks to :

Fluent in Laravel Packages and Postgres/Postgis? Consider contributing! We are looking for anyone that wants to help out!

Installation

  • Use 3.* for Laravel 5
composer require "mstaack/laravel-postgis:3.*"
  • Use 5.* for Laravel 6/7/8
composer require mstaack/laravel-postgis

For laravel >=5.5 that's all. This package supports Laravel new Package Discovery.

If you are using Laravel < 5.5, you also need to add the DatabaseServiceProvider to your config/app.php file.

'MStaack\LaravelPostgis\DatabaseServiceProvider',

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 MStaack\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'); // GEOGRAPHY POINT column with SRID of 4326 (these are the default values).
            $table->point('location2', 'GEOGRAPHY', 4326); // GEOGRAPHY POINT column with SRID of 4326 with optional parameters.
            $table->point('location3', 'GEOMETRY', 27700); // GEOMETRY column with SRID of 27700.
            $table->polygon('polygon'); // GEOGRAPHY POLYGON column with SRID of 4326.
            $table->polygon('polygon2', 'GEOMETRY', 27700); // GEOMETRY POLYGON column with SRID of 27700.
            $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. By default, all attributes are of type geography. If you want to use geometry with a custom SRID, you have to define an array called $postgisTypes. The keys of this assoc array must match the entries in $postgisFields (all missing keys default to geography), the values are assoc arrays, too. They must have two keys: geomtype which is either geography or geometry and srid which is the desired SRID. Note: Custom SRID is only supported for geometry, not geography.

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

class Location extends Model
{
    use PostgisTrait;

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

    protected $postgisFields = [
        'location',
        'location2',
        'location3',
        'polygon',
        'polygon2'
    ];

    protected $postgisTypes = [
        'location' => [
            'geomtype' => 'geography',
            'srid' => 4326
        ],
        'location2' => [
            'geomtype' => 'geography',
            'srid' => 4326
        ],
        'location3' => [
            'geomtype' => 'geometry',
            'srid' => 27700
        ],
        'polygon' => [
            'geomtype' => 'geography',
            'srid' => 4326
        ],
        'polygon2' => [
            'geomtype' => 'geometry',
            'srid' => 27700
        ]
    ]
}

$linestring = new LineString(
    [
        new Point(0, 0),
        new Point(0, 1),
        new Point(1, 1),
        new Point(1, 0),
        new Point(0, 0)
    ]
);

$location1 = new Location();
$location1->name = 'Googleplex';
$location1->address = '1600 Amphitheatre Pkwy Mountain View, CA 94043';
$location1->location = new Point(37.422009, -122.084047);
$location1->location2 = new Point(37.422009, -122.084047);
$location1->location3 = new Point(37.422009, -122.084047);
$location1->polygon = new Polygon([$linestring]);
$location1->polygon2 = new Polygon([$linestring]);
$location1->save();

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

Available geometry classes:

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