  1. Thanks for the great explanation. It was very easy to learn this content here.

    I have 2 questions:

    1. Are you missing S on $page->comment(s)? And in other loops too?
    foreach($page->comment as $comment)
    {
    // working with comment here…
    }

    2. In which column the comments are stored in comments table? Because we have only: Id, commendable_id, commendable_type and date.

  2. 2. Its an error in this article – in comments migrations we saw $table->date(‘body’); .. then must by $table->string(‘body’); or $table->text(‘body’); – body column is for the coment content 🙂

  3. Great article. I have one question: how would you return the inverse? Eg all comments of class Page?

  4. This was exactly what I was looking for. All my scenarios were discussed here. This is fantastic. Thank you very much.

  5. Hi, greate article!!!
    Just one small mistake: it should be $table→morphs(‘commentable’) not $table→morphs(‘comment’) which would automatically create two columns using the text passed to (it won’t add able, atleast not in L8). So it will result in commentable_id and commentable_type.

  6. this is useless if you not going to teach actionable events like attaching comment to post or sync without detaching!! stop supporting half baked articles

  7. The way you’ve explained this complex concept is truly impressive. Laravel’s flexibility never ceases to amaze me, and this article really highlights the power of polymorphic relationships in making our code cleaner and more efficient.
