Livewire - unable to call lazy data

[francoism90]

$this->findUserOrFail(1)
    ->getData() // I'm using the data trait
    ->include(
           'name',
           'email',
    );

It doesn't seem the include is being parsed/loaded.

Result:

htmlspecialchars(): Argument #1 ($string) must be of type string, Spatie\LaravelData\Support\Lazy\DefaultLazy given

My blade simple uses: {{ $user->email }}

If more info is needed, please let me know!

Thanks

This works:

$user->email->resolve()

However I don't think this is correct?

Maybe a loader for Livewire should be added: https://github.com/spatie/laravel-data/blob/main/docs/advanced-usage/use-with-inertia.md

Hi @francoism90,

This is correct behavior, calling include on a property will only affect when you're transforming a data class (toArray, toResponse, toJson, ....).

Inertia works a bit different then LiveWire since it will internally call toArray on the data object, that's a possible solution to this problem but you'll lose typing within your views.

Another solution could be to make lazy HtmlAble and then render the content, and also catch any property fetch or method on the lazyily incuded variable. In such case we could resolve the lazy object and pass on the call. This is a lot of magic, at this point I'm not certain if we want such a thing. But you could always implement it yourself by extending Lazy within your project.

@rubenvanassche Thanks for your reply! I don't fully understand the HtmlAble, but I'll look into it.

Would you recommend to use $user->email->resolve() as an alternative?

I didn't test <input type="text" wire:model="user.email" />, does this work fine on lazy attributes?

Thanks!

Yeah!

I didn't test , does this work fine on lazy attributes?

I would expect not, since the lazy prop will be used.

@rubenvanassche Sorry for bumping this, but could you please tell me how it should work with Htmlable?

I've found this post: https://itnext.io/laravel-the-fantastic-4-interfaces-renderable-6dbdd3c5e539

If I understand correctly, I need to check if the property is a Lazy instance and use resolve(), or when it's already resolved, return without this method.

This is what I'm doing now:

return $data->somelazy instanceof Lazy ? $data->somelazy->resolve() : $data->somelazy;

[rubenvanassche]

I would create a new Lazy class underneath the package Lazy class, extend HtmlAble which has a render method if I'm not mistaken and then use the code you've provided above.

Then in your data classes you would use your own implemented Lazy class instead of the default laravel-data one.

@rubenvanassche Thanks for your input! I'll try to extend the Lazy class with HtmlAble and see how this works out for us. :)
