Question

我试图在线获取非对象错误的属性：<span>{{$item->subcats->name}}</span>。如何获得产品子标识？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

您指的是错误的{{ $item->subcats->name}}

Answer 2

我应该将Product.php中从subats到subcat的方法的名称更正。

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

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

尝试在达到父属性时获取非对象的属性
