hasMany relationship Laravel 5.4 Trying to get property of non-object - php

Question

I have a relationship in my models with foreing keys, protected table.
This is my models:
Lot.php:
<?php
namespace App;
class Lot extends Model
{
protected $table = 'auct_lots_full';
protected $primaryKey = 'lot_id';
public function comments()
{
return $this->hasMany(Comment::class,'lot_id', 'lot_id');
}
}
Than related model Comment.php:
<?php
namespace App;
class Comment extends Model
{
public function lot()
{
return $this->belongsTo(Lot::class, 'lot_id', 'lot_id');
}
}
In my view I try to do this:
#foreach ($comments as $comment)
<dt>{{ $comment->lot }}</td>
#endforeach
It result this:
{"lot_id":391959148,"date":"2017-05-21","company":"MITSUBISHI","model_year_en":2005"}
Than in view I need to get only company information and I do this:
#foreach ($comments as $comment)
<td> {{ $comment->lot->company }}</td>
#endforeach
this result Error:
Trying to get property of non-object
I try to do this:
#foreach ($comments as $comment)
<td>
#foreach($comment->lot as $lot)
{{ $lot->company }}
#endforeach
</td>
#endforeach
And it also gives error:
Trying to get property of non-object
How can I get $comment->lot->company work?

Thanks, to Snapey from laracasts
when you do this
#foreach ($comments as $comment)
<td> {{ $comment->lot->company }}</td>
#endforeach
you are relying on EVERY comment having a lot and every lot having a company
You can use this to protect against empty properties
#foreach ($comments as $comment)
<td> {{ $comment->lot->company or '---'}}</td>
#endforeach
Then the loop will continue even if the lot does not have company
