php - 拉维尔 : Join two tables get the info from table one and get the first related image from table two

Question

我有两个表，一个是propertyDetails，另一个是propertyImages我已经完成了两个表之间的关系......

这是模型

属性详细信息

class PropertyDetail extends \Eloquent {
    protected $fillable = [];

    public function propImages()
    {
        return $this->hasMany('PropertyImage', 'property_details_id');
    }
}

表迁移

public function up()
    {
        Schema::create('property_details', function (Blueprint $table) {
            $table->increments('id');
            $table->enum('purpose', array('Sell', 'Rent'));
            $table->integer('property_owner_id')->unsigned();
            $table->integer('property_agent_id')->nullable();
            $table->integer('bedroom');
            $table->integer('dining_room');
            $table->integer('bathroom');
            $table->string('title', 100);
            $table->integer('price');
            $table->string('type', 120);
            $table->string('specify_type', 120);
            $table->text('details');
            $table->integer('active');
            $table->foreign('property_owner_id')->references('id')->on('property_owners')->onDelete('cascade');
            $table->timestamps();
        });
    }

属性图片

class PropertyImage extends \Eloquent
{
    protected $fillable = [];

    public function propertyImages()
    {
        return $this->belongsTo('PropertyDetail', 'property_details_id');
    }
}

表迁移

Schema::create('property_images', function(Blueprint $table)
        {
            $table->increments('id');
            $table->integer('property_details_id')->unsigned();
            $table->foreign('property_details_id')->references('id')->on('property_details')->onDelete('cascade');
            $table->binary('image');
            $table->timestamps();
        });
    }

我想做的是从表二 propertyImages 中选择所有带有第一张相关图像的 projectsDetails

我试过了

$properties = PropertyDetail::with('propImages')->get();
return View::make('admin.properties.view', compact('properties'));

在我看来

@foreach($properties as $property)
{{ HTML::image('images/propertyImages/'.$property->propImages->image, $property->title, array('width'=>767, 'height'=>384)) }}
@endforeach

得到

Undefined property: Illuminate\Database\Eloquent\Collection::$image

如错误所述，您正在尝试获取集合上的关系，该关系存在于该集合中的对象(记录)上。您需要遍历属性，并为每个属性获取它们的项目...

 @foreach ($properties as $property)
  // access property properties here
  @foreach ($property->image as $image)
    // access image properties here.
  @endforeach
@endforeach
