PHP: 8.2
Laravel Framework: 11
MySQL

We have roughly the following code on our website to represent the overall problem.

Post.php

class Post extends BaseModel
{
    public function blocks(): MorphMany
    {
        return $this->morphMany(Block::class, 'blockable');
    }
}

Block.php

class Block extends Model
{
    public function blockable(): MorphTo
    {
        return $this->morphTo();
    }

    public function alt(): string
    {
        $alt = '';

        if ($this->caption) {
            $alt = $this->caption;
        } else if ($this->blockable->title) {
            $alt = 'Block from ' . $this->blockable->title;
        }

        return $alt;
    }
}

PostController.php

$posts = Post::where('status_id', 1)
    ->with('blocks')
    ->get();

This code works correctly and returns the expected result. But by calling $this->blockable within the alt function, it produces extra (duplicate) MySQL queries to find the parent, even though it is already queried and present. Is there a way to let Laravel know that blockable has already been queried as the parent?

One quick solution we found was the following, but we feel there is a more eloquent way of achieving this.

public function alt(Post $blockable): string
{
    $alt = '';

    if ($this->caption) {
        $alt = $this->caption;
    } else if ($blockable->title) {
        $alt = 'Block from ' . $blockable->title;
    }

    return $alt;
}
