[TwigComponent][LiveComponent] Live attributes forwarding with attribute nesting

[norkunas]

I have a live form and a other custom component which wraps dialog component and is opened by live action and is also live.
Dialog accepts nested attributes via modal:* properties and I need to forward live attributes to that modal:* part.

For example:

<twig:Dialog
  open
  fullWidth
  modal:aria-labelledby="my-dialog-title"
/>

How could I forward all data-live attributes? Would like to avoid this:

<twig:Dialog
  modal:id="{{ attributes.only('id').all()['id'] }}"
  modal:data-live-name-value="{{ attributes.only('data-live-name-value').all()['data-live-name-value'] }}"
  modal:data-live-url-value="{{ attributes.only('data-live-url-value').all()['data-live-url-value'] }}"
  modal:data-live-props-value="{{ attributes.only('data-live-props-value').all()['data-live-props-value'] }}"
  modal:data-live-csrf-value="{{ attributes.only('data-live-csrf-value').all()['data-live-csrf-value'] }}"
  modal:data-live-events-to-emit-value="{{ attributes.only('data-live-events-to-emit-value').all()['data-live-events-to-emit-value'] ?? false }}"
  modal:data-live-events-to-dispatch-value="{{ attributes.only('data-live-events-to-emit-value').all()['data-live-events-to-dispatch-value'] ?? false }}"
/>

You could use a more direct syntax to avoid the situation you described

<twig:Dialog
  modal:id="{{ attributes.render('id') }}"
  modal:data-live-name-value="{{ attributes.render('data-live-name-value') }}"
  modal:data-live-url-value="{{ attributes.render('data-live-url-value') }}"
  modal:data-live-props-value="{{ attributes.render('data-live-props-value') }}"
  modal:data-live-csrf-value="{{ attributes.render('data-live-csrf-value') }}"
  ...

I did not understand your use case, and what you want to do... are you rendering the live attributes of your twig:Dialog component on the modal (non live) component ?

Little warning there, those attributes should not be considered public (they could change at any time).

I know that they could change anytime,thats why i want to forward all of them instead of defining manually. At first I missed that the events to emit/dispatch are dynamic,and not always present

Forward nested attributes, like I said in issue title not sure how that could be more clear :)

[norkunas]

I thought that it would be possible to do something like:

{% set modalAttrs = { modal: { ...attributes } } %}

<twig:Dialog
  {{ ...modalAttrs }}
/>

but this didn't work

Haha... ok :) Let's pretend my sentence stopped there!

{% set modalAttrs = { modal: { ...attributes } } %}

<twig:Dialog
  {{ ...modalAttrs }}
/>

It could not work as you expect, as this nested notation is a very specific use case, and cannot be implied for everyone.

You could manipulate the array of attributes and prefix all key with "modal:" before spreading it i guess.

[norkunas]

ah, that's right, keys are just strings..

too verbose to remap all the attributes :(

# Not perfect in term of readability but does the job

{% set nested = attributes|reduce((c, v, k) => c|merge({('modal:'~k): v}), {}) %}
<twig:Dialog {{ ... nested }} />

# Or if the order has no importance..

{% set nested = attributes|reduce((c, v, k) => {('modal:'~k): v, ...c}, {}) %}
<twig:Dialog {{ ... nested }} />
