Decorate a Presenter

[Mehdib92]

Hi,

I'd like to know if it's possible to decorate a Presenter. I'd like to override a function in the CartPresenter (I think for my need it will be easier than using the hook) but when I do it I have the message

You have requested a non-existent service "PrestaShop\PrestaShop\Adapter\Presenter\Cart\CartPresenter".

Is there a way to do that ?

Thanks

use PrestaShop\PrestaShop\Adapter\Cart\CartPresenter;

When I use bin/console debug:container, the CartPresenter is not listed, I think this is why it doesn't work

Hi.

In order to get the correct answer, it is necessary to specify the exact version of Prestashop.

[Mehdib92]

Sorry, I'm ont Prestashop 1.7.8.6

[ps8modules]

[ps8modules]

namespace = use

use PrestaShop\PrestaShop\Adapter\Cart;

I will try thank you

I think I don't understand 100% how it works.

 

I have created mymodule/src/Presenter/CartPresenter.php

namespace Mfacilities\OrderExtras\Presenter;

use Currency;
use Order as PrestashopOrder;
use OrderState;
//use PrestaShop\PrestaShop\Adapter\Cart;

class CartPresenter extends \PrestaShop\PrestaShop\Adapter\Presenter\Cart
{
    public $cartPresenter;

    public function __construct(CartPresenter $cartPresenter) {
        $this->cartPresenter = $cartPresenter;
    }
    /**
     * @param Cart $cart
     * @param bool $shouldSeparateGifts
     *
     * @return array
     *
     * @throws \Exception
     */
    public function present($cart, $shouldSeparateGifts = false)
    {
        die('TEST');
    }
}

If in my config/services.yml I add :

mycompany.mymodule.presenter.custom_cartpresenter:
    class: 'MyCompany\MyModule\Presenter\CartPresenter'
    arguments:
      - 'PrestaShop\PrestaShop\Adapter\Presenter\Cart\CartPresenter'

 

If I try like that (with a composer dumpautoload and a cache clear before), nothing happen.

Hi.

Please write me what you need to do so that we don't get confused 😉

I added the filetype when a customer upload a file for the customization. And I need to modify the display depending the filetype.

What I want to do is override the function addCustomizedData() in the PrestaShop\PrestaShop\Adapter\Presenter\Cart\CartPresenter to add the data everywhere.

I could do it with the hook actionPresentCart but I also need it on several pages of the site that's why I want to override/decorate the CartPresenter

[ps8modules]

I'm probably going to disappoint you, but it's unreal. Presenter cannot be overwritten like this. Even leading developers prefer to choose the path of using hooks and their own controllers.
Here is a sample of how others solve it, for example:

[Mehdib92]

Don't worry, you don't disappoint me, you just confirm what I was thinking. I just hoped that I was wrong

And do you think it's the same for the PrestaShop\PrestaShop\Core\Domain\Order\QueryResult\OrderProductCustomizationForViewing ? 

[ps8modules]

Yes, same problem.
Only hooks can be used.

Ok thanks you

Hey @Mehdib92, have you had any progress with this approach? I am struggling to decorate Product Presenter and looking for some references to study how it can be achieved, since official docs don't cover this.

What exactly do you wanna do? Did you check hook actionPresentProduct?
