Function from Model not recognized in CakePhp 3

Question

I am just making sure if I am making any mistakes. I am trying to access a function of a Model(Cart) from a different Controller(Product).

I got idea about this from a forum, i think it is right way to do. But i am getting this error

Unknown method addToCart

Can you please let me know where did i make mistake?

ProductController:

    public function initialize(){
         parent::initialize();
        $table =  $this->loadModel('Cart');// this works fine
        }

      public function addit() {
            $table->addToCart();

      }

Model:

 class CartTable extends Table{
      public function addToCart(){
        echo "hello from model";
       }

    }

Is there anything i need to do more? I did not find that helps me with this.So please wise people help me out.Thank you :)

Answer 1

You have to use this as following.

public function initialize(){
     parent::initialize();
     $this->loadModel('Cart');// this works fine
    }

  public function addit() {
       $this->Cart->addToCart();
  }

In cakephp 3 you can also lodel model by TableRegistery Just use this.

use Cake\ORM\TableRegistry;

Before using put this line on use section of controller

public function addit() {
    $cart_table = TableRegistry::get('Cart');

       $cart_table->addToCart();
}

You need to load your model in the method, and you do not need to assign it to a var.

    public function initialize(){
        parent::initialize();
    }

   public function addit() {
        $this->loadModel('Cart');
        $this->Cart->addToCart();
   }

This should get you up and running.

I have the same problem...

The solutions is very simple, just add this code in your model class :

namespace App\Model\Table;

So, your model will be like this :

namespace App\Model\Table;

use Cake\ORM\Table;

class CartTable extends Table{
  public function addToCart(){
    echo "hello from model";
  }
}

I hope this will help those who are having the same problem. Thanks
