升级到laravel 5.3后不进行分组

Question

This is the code that was working on laravel 5.2

$menus = CmsMenuItem::groupBy('menu_id')->get();

but now it throws error

SQLSTATE[42000]: Syntax error or access violation: 1055 Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'convertifier_cms.cms_menu_items.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by (SQL: select * from 'cms_menu_items' group by 'menu_id')

I have also tried

 `strict => false` 

in database.php but no effect

Answer 1

Try this for database config.

 'mysql' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST', 'localhost'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
            'password' => env('DB_PASSWORD', ''),
            'charset' => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix' => '',
            'strict' => false,
            'engine' => null,
        ],

and use query like this way

$menus =DB::table('cms_menu_item')
    ->select('*')
    ->groupBy('menu_id')
    ->get();
