Question

我有2个表，其中1个产品有很多prodphotos

我可以从具有相同ID的产品中检索所有prodphotos，但我的情况是列出所有products但仅从prodphotos拍摄1张照片。

控制器：

public function daftarproduk()
{
    $produks = Product::orderBy('created_at', 'desc')->get();

    $select = Product::with('prodphotos')->firstorfail();
    $photo = $select->prodphotos->pluck('photo');

    $kategori = Category::orderBy('created_at', 'asc')->get();

    return view('guest.daftarproduk')
          ->with('produks',$produks)
          ->with('kategori',$kategori)
          ->with('select',$select)
          ->with('photo',$photo);
}

查看：

@foreach($produks as $value)
    <div class="col-xs-6 col-md-4 col-lg-3 box-product-outer">
        <div class="box-product">
            <div class="img-wrapper">
                <a href="detail/{{$value->id}}/{{str_slug($value->name)}}">
                    <img alt="Product" src="images/gambarproduk/thumb_{{ i dont know what i must throw here to only get first picture }}">
                </a>
            </div>
            <h6><a href="detail/{{$value->id}}/{{str_slug($value->name)}}">{{$value->name}}</a></h6>
        </div>
    </div>
@endforeach

我不知道从控制器获取$select或$photo的第一个照片名称时必须使用的功能。或者我的foreach逻辑错了？请帮帮我。

将hasOne类型的精选照片关系添加到Product模型中。

Product型号

public function featuredPhoto() {
    return $this->hasOne(PhotosModel);
}

在您的控制器中

public function daftarproduk()
{
    // Get the products with featured image
    $produks = Product::with('featuredPhoto')->orderBy('created_at', 'desc')->get();
    $kategori = Category::orderBy('created_at', 'asc')->get();

    return view('guest.daftarproduk')
          ->with('produks',$produks)
          ->with('kategori',$kategori);
}

查看

@foreach($produks as $value)
    <div class="col-xs-6 col-md-4 col-lg-3 box-product-outer">
        <div class="box-product">
            <div class="img-wrapper">
                <a href="detail/{{$value->id}}/{{str_slug($value->name)}}">
                    <img alt="Product" src="images/gambarproduk/thumb_{{ $value->featuredPhoto->photo }}">
                </a>
            </div>
            <h6><a href="detail/{{$value->id}}/{{str_slug($value->name)}}">{{$value->name}}</a></h6>
        </div>
    </div>
@endforeach

Laravel从HasMany关系中选择第一行
