I ran into this issue too. The only way I could figure to do it was to create another database connection entry in my database.php config file.

'mysql' => array(
    'driver'    => 'mysql',
    'read' => array(
        'host' => 'read-host',
        'database'  => 'read-database',
        'username'  => 'read-username',
        'password'  => 'read-password',		       
    ),
    'write' => array(
        'host' => 'write-host',
        'database'  => 'write-database',
        'username'  => 'write-username',
        'password'  => 'write-password',		       
    ),
    'charset'   => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix'    => '',
),
'mysql-write' => array(
    'driver' => 'mysql',
    'host' => 'write-host',
    'database'  => 'write-database',
    'username'  => 'write-username',
    'password'  => 'write-password',		       
    'charset'   => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix'    => '',
),

Then when you need to force a select using the write connection, you can do this:

DB::connection('mysql-write')->select(...);

Or if you are using Eloquent:

User::on('mysql-write')->find(1);

See: http://laravel.com/api/5.1/Illuminate/Database/Eloquent/Model.html#method_onWriteConnection

It allows you to query the model on the write connection.

Example use:

User::onWriteConnection()->find(1);

        $r = DB::connection($this->connection)
                ->selectFromWriteConnection("CALL maker_create_service_order(?, ?, ?, ?, ?, ?);",[
                    $creationId, $accountId, $storeId, $storeProductId, $quantity, $total
                ]);

This works fine for me.

Is this working in laravel 5.3 tried to do so by its seems that its not working
