Level 7 display relationship data in blade using one to many - laravel

Question

whats wrong why in blade don't want to show the LEVEL name
controller:
$streams=Stream::with('level')->get();
return view('streams.index',compact('streams'));
Stream Model:
public function level()
{
return $this->belongsTo('App\Models\Level', 'level_id');
}
Level Model:
public function stream()
{
return $this->hasMany('App\Models\Stream', 'level_id');
}
Blade Index:
#foreach($streams as $stream)
<tr>
<th scope="row">#</th>
<td>{{$stream->name}}</td>
<td>{{$stream->code}}</td>
<td>
{{$stream->level->name}}
</td>
<td>
<tr/>
#endforeach
Also tried:
#foreach($streams as $stream)
<tr>
<th scope="row">#</th>
<td>{{$stream->name}}</td>
<td>{{$stream->code}}</td>
#foreach($stream as $level)
<td>
{{$level->name}}
</td>
#endforeach
<td>
<tr/>
#endforeach

Answer 1

Your first Blade template is almost correct.
The issue is that one or more of your records has no Level assigned (level_id=null), but you're still trying to pull the name property from $stream->level, which is null.
Simply add a check for $stream->level before trying to access/print its properties. For example:
#if($stream->level)
{{ $stream->level->name }}
#endif
or
{{ $stream->level ? $stream->level->name : 'No Level Attached' }}
or
{{ optional($stream->level)->name }}
etc.
