包简介
Postgis extensions for laravel. Aims to make it easy to work with geometries from laravel models
README 文档
README
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:
