Why am I getting “TableRegistry not found” in CakePhP 3.0?

问题

I have a class full of static functions that I call UtilityFunctions in my Model/ directory. But that class cannot access TableRegistry::Get even though the "use" statements are in place. Below is the code and the error.

namespace App\Model\Table;
use Cake\ORM\TableRegistry;
use App\Model\Entity\Device;

class UtilityFunctions {
    public static function getDevice($deviceInfo) {
        $devicesTable = TableRegistry::get('Devices'); // TableRegistry not found
        $query = $devicesTable->findByDeviceInfo($deviceInfo);
       ...
    }
}

"Class \u0027UtilityFunctions\TableRegistry\u0027 not found", "/var/www/myserver/src/Model/Custom/UtilityFunctions.php",115

I know that this might be a really late reply, but it may be an issue with you not inserting use Cake\ORM\TableRegistry; at the top of the code.

I had the same issue. I added that line of code and it worked

It depends on the order of the lines. If you place namespace first, PHP will look inside the given namespace unless you specify a \ first in the use statement . E.g.

namespace App\Model\Table;
use Cake\ORM\TableRegistry;

will look for App\Model\Table\Cake\ORM\TableRegistry, which obviously isn't right.

But this will work:

use Cake\ORM\TableRegistry;
namespace App\Model\Table;

Or

namespace App\Model\Table;
use \Cake\ORM\TableRegistry;
