Unable to CREATE PRIMARY INDEX for couchbase bucket. on UBUNTU 14.04

Question

I am trying to get data from couchbase bucket using laravel 4.2 . And facing issue related to PRIMARY INDEX. Below are the details. Can someone please suggest where I am doing wrong. Thanks.

Controller:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests;
use CouchbaseCluster;

class HomeController extends Controller {

    public function index() {


//        phpinfo();die;

//        
    $Cluster  =  New  CouchbaseCluster ( 'http://127.0.0.1:8091' ); 
    $Bucket = $Cluster->OpenBucket('beer-sample');

// Retrieve a document

    Try {
        $Result = $Bucket->Get('21St_amendment_brewery_cafe');
    } Catch (Exception $E) {
        Echo "CouchbaseException:" . $E->getMessage() . " \ N ";
    }
    $doc = Json_decode($Result->Value, True);
    var_dump($doc);die;
    }

}

getting below error message:

CouchbaseException in CouchbaseBucket.class.php line 196:
The key does not exist on the server

Then I changed my controller code and ran it again.

Controller(Updated):

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests;
use CouchbaseCluster;

class HomeController extends Controller {

    public function index() {


//        phpinfo();die;
        $query = 'SELECT * FROM `beer-sample` limit 2';
        $res = \DB::connection()->bucket('beer-sample')->select($query);
        var_dump($res);die;

    }

}

Then I am getting this error.

QueryException in Connection.php line 673:
No primary index on keyspace beer-sample. Use CREATE PRIMARY INDEX to create one. (SQL: SELECT * FROM `beer-sample` limit 2)

It seems both errors are related to (PRIMARY) Key. So, I tried to create primary key from my controller and ./cbq . But cases are failing. Below are the details.

Controller logic to create PRIMARY KEY:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests;
use CouchbaseCluster;

class HomeController extends Controller {

    public function index() {


//        phpinfo();die;
        $query = 'CREATE PRIMARY INDEX `beer-sample-primary-index` ON `beer-sample` USING GSI WITH {"defer_build":true};';
        $res = \DB::connection()->bucket('beer-sample')->select($query);
        var_dump($res);die;      
  }

}

Page is throwing below error:

QueryException in Connection.php line 673:
GSI CreatePrimaryIndex() - cause: Fails to create index. There is no available index service that can process this request at this time. Index Service can be in bootstrap, recovery, or non-reachable. Please retry the operation at a later time. (SQL: CREATE PRIMARY INDEX `beer-sample-primary-index` ON `beer-sample` USING GSI WITH {"defer_build":true};)

Query from ./cbq also thrown similar error.

srturaka@srturaka-pc:/opt/couchbase/bin$ ./cbq

        }
    ],

    }
}

Answer 1

I am not sure if this is a proper way, but my issue got resolved after I changed my query to below.And I am able to perform CRUD operations.

$query = 'CREATE PRIMARY INDEX `beer-sample-primary-index` ON `beer-sample` USING View'; 

"VIEW instead of GSI;"

Answer 2

For me bucket name with '-' doesnt work while creating index. So beer-sample doesnt work but beer_sample works.
