我有3个模特:Pizzerie,Pizze,每个成分都有自己的关系
class Pizzerie extends Model {
protected $table = 'pizzerie';
public function pizze()
{
return $this->hasMany('App\Pizze', 'pizzerie_id');
}
}
class Pizze extends Model {
protected $table = 'pizze';
public function ingredienti()
{
return $this->belongsToMany('App\Ingredienti', 'pizze_ingredienti');
}
public function pizzeria()
{
return $this->belongsTo('App\Pizzerie');
}
}
class Ingredienti extends Model {
protected $table = 'ingredienti';
public function pizze()
{
return $this->belongsToMany('App\Pizze', 'pizze_ingredienti');
}
}
我正在寻找一个允许我在我的视图中循环的查询
@foreach($data as $pizzeria)
<p>{{ $pizzeria->name }} Has pizze: </p>
@foreach($pizzeria as $pizze)
<p>{{ $pizza->name }} Has ingredients: </p>
<ul>
@foreach($pizza as $ingredient)
<li>{{ $ingredient->name }}</li>
@endforeach
</ul>
@endforeach
@endforeach
无法弄清楚如何获得它:/
答案 0 :(得分:1)
我无法评论Margus Pala的答案:(但你的查询应该是
$data = \App\pizzerie::with('pizze. ingredienti')->get();
由于急切的加载问题,这是一个重要的问题(循环查询太多)

试试这个,它会在每个foreach循环中得到下一个关系Collection。
@foreach($data as $pizzeria)
<p>{{ $pizzeria->name }} Has pizze: </p>
@foreach($pizzeria->pizze as $pizze)
<p>{{ $pizza->name }} Has ingredients: </p>
<ul>
@foreach($pizze->ingredienti as $ingredient)
<li>{{ $ingredient->name }}</li>
@endforeach
</ul>
@endforeach
@endforeach
