错误消息

方法衣柜图像不存在。（查看：C：\ laragon \ www \ wasamar \ resources \ views \ main_app \ admin \ wardrobe.blade.php）

我有这个问题，当我想打电话给我的衣柜形象类来展示衣柜的装扮图像。

WARDROBE MODEL

<?php

namespace App\Wasamar;

use Illuminate\Database\Eloquent\Model;

class Wardrobe extends Model
{
/**
 * The database table used by the model.
 *
 * @var string
 */

protected $table = 'wardrobes';

public function wardrobeimage(){

    return $this->hasMany('App\Wasamar\Wardrobeimage','wardrobe_id');
}
}

WARDROBE IMAGE CLASS

<?php

namespace App\Wasamar;

use Illuminate\Database\Eloquent\Model;

class Wardrobeimage extends Model
{
/**
 * The database table used by the model.
 *
 * @var string
 */
protected $table = 'wardrobeimages';


function wardrobe(){

    return $this->belongsTo('App\Wasamar\Wardrobe','id');
}
}

所以当我这样做时它会提示错误

<?php 
$wardrobeAttires = Wardrobe::where('user_id',$user->id)->get(); 
?>

$wardrobeAttires->wardrobeimage()->where('wardrobe_attire_view',0)->get();

Answer 1

关系设置具有误导性。衣柜里有很多衣柜图片。命名约定应该是wardrobeimages（）。如果wardrobe_id是外键，则关系应为：

衣柜型号：

public function wardrobeimages(){

    return $this->hasMany('App\Wasamar\Wardrobeimage','wardrobe_id');
}

<强> Wardrobeimage：

function wardrobe(){

    return $this->belongsTo('App\Wasamar\Wardrobe','wardrobe_id');
}

在控制器中：

$wardrobeAttires = Wardrobe::with(['wardrobeimage'=>function($query)
                       {
                            $query->where('wardrobe_attire_view',0);
                      }])
                 ->where('user_id',$user->id)->get();

这给出了衣柜的集合：

foreach($wardrobeAttires as  $wardrobeAttire)
{
   foreach($wardrobeAttire->wardrobeimages as $wardrobeimage)
   {
             print_r($wardrobeimage);
   }
}

我想通了，但感谢大家的支持。

@foreach( $wardrobeAttires as $wardrobeAttire) 
                            <div class="row">
                                <div class="small-4 columns">

                                    <div class="image-wrapper overlay-slide-in-left">

                                        @if( count($wardrobeAttire->wardrobeimages()->where('wardrobe_attire_view',0)->first()) === 0 )
                                            <img src="{{ domain_name() . '/f-assets/img/' . 'wardrobe_attire_default_image.png' }}" alt="Attire image" />
                                        @else
                                            @if( count($wardrobeAttire->wardrobeimages()->where('wardrobe_attire_view',0)->get()) >= 1 )
                                                @foreach($wardrobeAttire->wardrobeimages()->where('wardrobe_attire_view',0)->get() as $wardrobeAttireImage)
                                                    <img src="{{ domain_name().'/ws-uploads/wardrobe-attire-image/thumbnail/'.$wardrobeAttireImage->new_name }}" alt="Attire image" />
                                                @endforeach
                                            @endif
                                        @endif

                                        <div class="image-overlay-content">
                                            <h2>.overlay-slide-in-left</h2>
                                            <p class="price">$2319.99</p>
                                            <a href="#" class="button">Buy Me</a>
                                        </div>

                                    </div>

                                </div>
                            </div>
                        @endforeach

而不是$ wardrobeAttires应该是$ wardrobe在@foreach循环内部，这就是bug。
