Laravel postgis extension

Solemnly declare

• This is based on Phaza\Laravel-Postgis to modify Non-original;

修改位置

1. 修改了readme.md 关于lumen5.4 安装的注册服务，需要注册两个服务(见下文)。
2. 添加了几何数据迁移命令$table->geometry('geom');
3. 添加 $location1->location = new GeomPoint(37.422009, -122.084047); 实现gis几何数据直接利用模型插入

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 for Laravel 5.3.*;5.4.*
• Use for lumen 5.3.*;5.4.*

Installation

composer require shaozeming/lumen-postgis 'dev-master'

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

    'Shaozeming\LumenPostgis\DatabaseServiceProvider',

That's all.

Lumen Next add the DatabaseServiceProvider to your bootstrap/app.php file.

     $app->register(Bosnadev\Database\DatabaseServiceProvider::class);   //多添加这个后，就可以解决问题。
     $app->register(Shaozeming\LumenPostgis\DatabaseServiceProvider::class);

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 Shaozeming\LumenPostgis\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->geometry('geom');
            $table->polygon('polygon');
            $table->timestamps();
        });
    }

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

}

Available blueprint geometries:

• point
• geometry
• 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 Shaozeming\LumenPostgis\Eloquent\PostgisTrait;
use Shaozeming\LumenPostgis\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->geom = new GeomPoint(37.422009, -122.084047);  //这个可以执行成功实现ORM操作gis几何数据。
$location1->save();

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

Available geometry classes:

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