How to retrieve user name from user table by using data (user_id) from another table having relationship

I have two models

User.php

public function opportunities()
{
    return $this->hasMany('AppOpportunity');
}

Opportunity.php

public function user()
{
    return $this->belongsTo('AppUser');
}    

I have user_id column in opportunities table and inserted user id (from user table using Auth) every time user posts record.

Now i need a view to return “this post is posted this user”.

First I find the post id by

$posts =  Opportunity::find($id);
$posted_by = User::find($posts->user_id);
return view('opportunity.detail')->with('post', $posts, 'posted_by', $posted_by);

I have rendered user name by

But I got undefined constant in the view file $posted_by while $post is fine. Am I doing it in right way or not? I am passing two array variable to the post and its not working. Any help will be appreciated.
