Laravel miltiple level relationship with limit() - laravel

Question

I have some problem with Laravel Eloquent and need your help.
I want to display 1 replies of each comment of single post.
Here is my tables
posts (id,title)
id | title
---------------------
1 | My post
---------------------
comments(id,post_id,comment,parent_id)
id | post_id | comment | parent_id
-----------------------------------------
1 | 1 | First comment | null
-----------------------------------------
2 | 1 | Second comment | null
-----------------------------------------
3 | null | 3rd comment | 1
-----------------------------------------
4 | null | 4th comment | 1
-----------------------------------------
5 | null | 5th comment | 2
-----------------------------------------
6 | null | 6th comment | 2
-----------------------------------------
My model (Eloquent)
class Post extends Model
{
public function comments()
{
return $this->hasMany('Comment', 'post_id');
}
}
---------------------
class Comment extends Model
{
public function reply()
{
return $this->hasMany('Comment', 'parent_id');//self relationship
}
}
My query function
public function getPost($postId){
$posts = Post::with(['comment.reply'=>function($q){
$q->limit(1);
}])
->find($postId);
return $posts;
}
And I get result
{[
id=>1,
title=>'My post',
'comments'=>[
0=>[
id=>1,
comment=>'First comment',
parent_id=>null,
post_id=>1,
reply=>[
0=>[........(comment id:3).......]
]
],
1=>[
id=>2,
comment=>'Second comment',
parent_id=>null,
post_id=>1,
reply=>null
]
]
]}
But I want like this
{[
id=>1,
title=>'My post',
'comments'=>[
0=>[
id=>1,
comment=>'First comment',
parent_id=>null,
post_id=>1,
reply=>[
0=>[........(comment id:3,4)........]
]
],
1=>[
id=>2,
comment=>'Second comment',
parent_id=>null,
post_id=>1,
reply=>[
0=>[........(comment id: 5,6).........]
]
]
]
]}
Please kindly help!

Try this:
$posts=Post::where(['id'=>1])->with(['comments'=>function($query)
{
$query->with(['replies'=>function($query)
{
$query->limit(1);
}]);
}])->first();
print_r($posts);
