尝试在达到父级属性时获取非对象的属性

Question

我试图在网上获取非对象错误的属性： <span>{{$item->subcats->name}}</span> 。 如何获得产品子类别的名称？ 我的产品型号：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
    protected $guarded=[];

    public function subcats(){
        return $this->belongsTo(Subcat::class);
    }

    public function comments(){
        return $this->hasMany(Comment::class);
    }
}
my Subcat Model:
<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Subcat extends Model
{
    protected $guarded=[];

    public function cats(){
        return $this->belongsTo(Cat::class);
    }

    public function products(){
        return $this->hasMany(Product::class);
    }
}
the blade is:
@extends('template.master')
@section('content')

        @forelse($product as $item)
            <div class="col-lg-4">
                <a href="/product/{{$item->id}}">{{$item->title}}</a><br>
                <span class="caret">{{$item->description}}</span><br><br>
                <span>Price :</span><span class="caret">{{$item->price}}</span><br>

                 <span>{{$item->subcats->name}}</span> 
            </div>
        @empty
        @endforelse
@endsection

Answer 1

您将其命名为错误的{{ $item->subcats->name}}

Answer 2

我应该将Product.php中方法的名称从subcats更改为subcat。

public function subcat(){
        return $this->belongsTo(Subcat::class);
    }

然后使用： @foreach($product as $item) {{$item->subcat->name}} @endforeach
