Laravel blade one-to-one relationship in #foreach loop - laravel

Question

I have a problem with show one to one relationship in Laravel.
I have that tables in DB:
manufacturers with defaul Laravel id column and cashregisters with manufacturer_id column releated to id from manufacturers table.
In models I do that:
Cashregister
class Cashregister extends Model
{
protected $table = "cashregisters";
public function manufacturer(){
return $this->hasOne('App\Manufacturer','id');
}
}
Manufacturer
class Manufacturer extends Model
{
protected $table = "manufacturers";
public function cashregisters(){
return $this->belongsTo('App\Cashregister');
}
}
I think this is ok. Next I do in CashregisterController that in index():
$cashregisters = Cashregister::all();
return view('cashregisters.index')->withCashregisters($cashregisters);
In cashregisters index View i do that loop:
<tbody>
#foreach ($cashregisters as $cashregister)
<tr>
<th>{{ $cashregister->id }}</th>
<td>{{ $cashregister->manufacturer_id }}</td>
......
<td>{{ $cashregister->DataNastPrzegUrzFisk }}</td>
#endforeach
</tr>
</tbody>
And it works great. Show everything from cashregisters table.
I want to display Manufacturer name instead of manufacturer_id, so I try do this that:
<td>{{ $cashregister->manufacturer->name }}</td>
Bu I got an error.
Next I searchover internet and try do that thing
#foreach ($cashregisters as $cashregister)
<tr>
<th>{{ $cashregister->id }}</th>
#foreach ($cashregister->manufacturer() as $item)
<td>{{ $item->name}}</td>
#endforeach
......
<td>{{ $cashregister->DataNastPrzegUrzFisk }}</td>
#endforeach
</tr>
</tbody>
But this piece of code show nothing :( Can anyone help me to fix that. When I after all table do that code:
<td>{{ $cashregister->manufacturer->name}}</td>
it show some information, so I think relationship is ok.

Answer 1

You need to set local key for manufacturer, like this:
class Cashregister extends Model
{
protected $table = "cashregisters";
public function manufacturer(){
return $this->hasOne('App\Manufacturer','id', 'manufacturer_id');
}
}

Answer 2

Use with() to load the relation:
$cashregisters = Cashregister::with('manufacturer')->all();
Then this will show the manufacturer:
$cashregister->manufacturer->name
