Display EmbedsMany Data in Laravel MongoDB

问题

I have a database with schemes like below:

{
    "title": "Simple new",
    "username": "soimah",
    "_id": ObjectId("5569b157bed33066220041ac"),
    "comments": [{
    "subject": "comment 1",
    "_id": ObjectId("5569cc28bed330693eb7acd9")
    }]
}

I would like to display the title and subject.

My Model:

<?php
namespace App\Models;
use Jenssegers\Mongodb\Model as Eloquent;

class Testo extends Eloquent {
    protected $collection = 'testIN';
    protected $fillable = array('title', 'comments.subject');

    public function comments() {
    return $this - > embedsMany('comments');
    }
}
?>

My Controller:

public function ambl() {
    $g = new Testo();
    $g = Testo::where('username', '=', 'soimah') - > first() - > comments;
    return View('layouts/in', array(
    'g' => $g
    ));
}

My View :

<?php
    foreach($g as $j) {
      echo $j['comments.subject'];
    }
?>

Data comments.

subject not show.

Please help me to show them.

I see two issues there.

The method Jenssegers\Mongodb\Model::embedsMany() expects parameter 1 to be the fully qualified name of another model, just like hasMany in Eloquent does. You should create a Model Comment and adjust your Testo model to the following:

<?php

namespace App\Models;

use Jenssegers\Mongodb\Model as Eloquent;

class Testo extends Eloquent 
{
    protected $collection = 'testIN';

    protected $fillable = array('title', 'comments.subject');

    public function comments()
    {
        return $this->embedsMany(Comment::class);
    }
}

In your view, the variable $j should then be an instance of Comment. You can access the subject of a comment like this:

// Raw PHP view:
<?php
foreach ($g as $j) 
{
    echo $j->subject;
}
?>

// Blade syntax:
@foreach($g as $j)
    {{ $j->subject }}
@endforeach
