我是 MongoDB 的新手。
我正在使用Jensegger/Laravel-MongoDB Moloquent功能来处理 Mongo DB。
我正在尝试用这种方法创建一个集合的索引:-
Schema::collection('events', function ($table) {
$table->index(['location' => '2dsphere']);
});
但是,我收到错误:-
Class Jenssegers\Mongodb\Schema' not found
我也添加了这两个:-
use Jenssegers\Mongodb\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
我有一个控制器方法,如下所示: -
public function fetchMongoTest(Request $request){
$error = FALSE;
$respond = array();
$detail = array();
$err_message = array();
$err_validation = array();
$api_code = 2001;
try
{
if ($request->isMethod('post'))
{
$latitude = (float)$request->latitude;
$longitude = (float)$request->longitude;
$status = 1;
$mongoData = array();
$monTestObj = new Mongotest;
Schema::collection('events', function ($table) {
$table->index(['location' => '2dsphere']);
});
$monTestObj->location = ['type' => 'Point', 'coordinates' => [100.0, 0.0]];
$monTestObj->save();
$users = MongoTest::where('loc', 'near', [
'$geometry' => [
'type' => 'Point',
'coordinates' => [
$longitude,
$latitude
]
],
'$maxDistance' => 10,
]);
foreach($users as $u)
{
print_r($u->name);
}
}
else
{
$status = 0;
$message = Config::get('customConfig.api_messages.ENG.post_request_mandatory');
$err_message[] = $message;
}
}
catch(Exception $e)
{
$status = 0;
echo $e->getMessage(); die;
$message=Config::get('customConfig.api_messages.ENG.exception_error');
}
$response['status'] = $status;
$response['message'] = $message;
$response['details'] = $detail;
$response['error'] = $err_message;
$response['error_validation_key'] = $err_validation;
$response['api_version'] = $this->api_version;
$response['api_code'] = $api_code;
$respond['fetch-activity-list-prime'] = $response;
$jsonResult = json_encode($respond);
header('Content-Type: application/json; charset=utf-8');
echo $jsonResult ;
exit();
}
如何检查集合是否存在,如果不存在,则创建一个新集合?
编辑:
这是我的 MongoTest 模型:-
<?php
namespace App\Http\Model;
//use Illuminate\Database\Eloquent\Model;
use Moloquent;
class MongoTest extends Moloquent
{
protected $connection = 'mongodb';
protected $collection = 'test';
//protected $collection = 'rh_country_help_text';
}
