Property [***] does not exist on this collection instance Laravel eloquent relationship - laravel

Question

In my Post Model
public function user()
{
return $this->belongsTo('App\User');
}
And in the User Model
public function posts()
{
return $this->hasMany('App\Post');
}
Now I am trying to get the comments of a specific user
$user= User::where('name', 'like', '%Mat%')->first();
return $user->posts->comment;
But it shows
Property [comment] does not exist on this collection instance.

Answer 1

The user has many posts which therefore returns a collection, you will need to loop over this to get your comments out. I.e.
$user = User::where('name', 'like', '%Mat%')->first();
$user->posts->each(function($post) {
echo $post->comment;
});
See the documentation on Laravel Collections

Answer 2

I think you can try this :
$user= User::with('post')->where('name', 'like', '%Mat%')->get();
$postComment = array();
foreach($user->post as $post){
$postComment = $post->comment;
}
return $postComment;
Hope this help for you !!!

Answer 3

If you want to have all comments you can use the following code:
$comments = [];
$user = User::where('name', 'like', '%Mat%')->with(['post.comment' => function($query) use (&$comments) {
$comments = $query->get();
}])->first();
return $comments;

Answer 4

Property [comment] does not exist on this collection instance.
The above error occurs because the Posts function returns a collection. Now you will have to traverse through each element of the collection.
Since, you are returning $user->posts()->comment, I am assuming you need it in the form of an array and don't have to simply echo them out, one by one. So you can store them all in an array & then process it whatever whay you like.
$comments = array();
$user->posts()->each(function $post){
$comments = $post->comment;
}
return $comments;
