Passing Dynamic Attributes to Component

[sqwk]

When using a component inside a box, I cannot pass any attributes to the component from the box:

{% component 'renderForm' %}

handle: form
name: Form
form:
    fields:
        form:
            label: Form
            type: text
components:
    renderForm:
        addToLayout: true
        properties:
            formCode: "{{box.form}}"

What is the suggested method to pass on form field to components?

The yaml code is not processed by Twig, so you cannot use variables in there.

The only method to pass the boxes data to a component is currently by fetching it in the component itself:
https://docs.boxes.offline.ch/use-cases/components.html#accessing-boxes-inside-the-component

If you control the components logic, this is rather easy:
https://github.com/OFFLINE-GmbH/oc-forms-plugin/blob/bcaf20458fad71e2b5cbcf8ee8f742d3d7886f01/components/RenderForm.php#L280

It is probably also possible to listen to a specific October Event that is triggered before the component is run and access the data this way.

Ah, I have also tried setting the code in the partial like so, as that's actually documented this way in the October docs:

[renderForm]
formCode = "{box.form}"
==
{% component 'renderForm' %}
…

That also doesn't work. I have now resorted to creating a custom component that extends the other component and overrides the necessary method + bunch of symlinks for the component markup and assets:

<?php

namespace Author\Customisations\Components;

use \Renatio\FormBuilder\Components\RenderForm;

class CustomRenderForm extends RenderForm
{
    public function init() { }

    public function boxesInit()
    {
        $boxesBox = $this->getBoxesBox();
        $this->setProperty('formCode', $boxesBox->form);
        return parent::init();
    }

}
