How insert into morph related model in eloquent
<p>Using the laravel ducmunet example :</p>

<p>There are there table like </p>

<pre><code>posts
    id - integer
    title - string
    body - text

videos
    id - integer
    title - string
    url - string

comments
    id - integer
    body - text
    commentable_id - integer
    commentable_type - string

And 3 model (post, command and video) .
Comment model has morphTo relation with post and video.

&lt;?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Comment extends Model
{
    /**
     * Get all of the owning commentable models.
     */
    public function commentable()
    {
        return $this-&gt;morphTo();
    }
}

class Post extends Model
{
    /**
     * Get all of the post's comments.
     */
    public function comments()
    {
        return $this-&gt;morphMany('App\Comment', 'commentable');
    }
}

class Video extends Model
{
    /**
     * Get all of the video's comments.
     */
    public function comments()
    {
        return $this-&gt;morphMany('App\Comment', 'commentable');
    }
}
</code></pre>

<p>Is there a solution for insert new record into model related  to the comment (video or post model). </p>

<p>For example if i have an instace of comment model by this instrument :</p>

<pre><code>$nc = comment::find(3);
</code></pre>

<p>Now how can i add new post or video related to $nc comment.</p>

<p>I can't use save method because save method argument is an instance of post or video model but i don't know which model related to $nc comment by polymorphic.<br/><br/><br/>
in another word i will add a new post or video to a comment existing ($nc).</p>
