php - 分组相关的产品属性

Question

我有一个产品表：

products
-id
-name
-image

还有一个 product_atts 表：

product_attributes
-product_id (FK)
-size (1, 2)
-memebership (1, 2, 3, 4, 6, 11)
-price

现在，当查询product_attributes表并加入products表时，我得到了所有的变化：

Array
(
    [0] => stdClass Object
        (
            [name] => Product 1
            [image] => Product1.png
            [size] => 1
            [membership] => 1
            [price] => 0.00
        )

    [1] => stdClass Object
        (
            [name] => Product 1
            [image] => Product1.png
            [size] => 1
            [membership] => 2
            [price] => 0.00
        )

    [2] => stdClass Object
        (
            [name] => Product 1
            [image] => Product1.png
            [size] => 1
            [membership] => 3
            [price] => 0.00
        )

    [3] => stdClass Object
        (
            [name] => Product 1
            [image] => Product1.png
            [size] => 1
            [membership] => 4
            [price] => 0.00
        )

    [4] => stdClass Object
        (
            [name] => Product 1
            [image] => Product1.png
            [size] => 1
            [membership] => 6
            [price] => 0.00
        )

    [5] => stdClass Object
        (
            [name] => Product 1
            [image] => Product1.png
            [size] => 1
            [membership] => 11
            [price] => 0.00
        )

    [6] => stdClass Object
        (
            [name] => Product 1
            [image] => Product1.png
            [size] => 2
            [membership] => 1
            [price] => 0.00
        )

    [7] => stdClass Object
        (
            [name] => Product 1
            [image] => Product1.png
            [size] => 2
            [membership] => 2
            [price] => 0.00
        )

    [8] => stdClass Object
        (
            [name] => Product 1
            [image] => Product1.png
            [size] => 2
            [membership] => 3
            [price] => 0.00
        )

    [9] => stdClass Object
        (
            [name] => Product 1
            [image] => Product1.png
            [size] => 2
            [membership] => 4
            [price] => 0.00
        )

    [10] => stdClass Object
        (
            [name] => Product 1
            [image] => Product1.png
            [size] => 2
            [membership] => 6
            [price] => 0.00
        )

    [11] => stdClass Object
        (
            [name] => Product 1
            [image] => Product1.png
            [size] => 2
            [membership] => 11
            [price] => 0.00
        )

)

有没有办法让我得到如下所示的结果：

Array
(
    [0] => stdClass Object
        (
            [name] => Product 1
            [image] => Product1.png
            [size] => stdClass Object
                    (
                        [0] => 1,
                        [1] => 2                        
                    )
            [membership] => stdClass Object
                    (
                        [0] => 1,
                        [1] => 2,
                        [2] => 3,
                        [3] => 4,
                        [4] => 6,
                        [5] => 11                       
                    )
            [price] => 0.00
        )
)

它使在我的 UI 等中使用这些数据变得更加容易。

Answer 1

你可能还没有意识到，但是使用 Eloquent，你已经拥有了一切。一旦您在模型中创建了关系，您只需要一个根模型来访问与其相关的每一个模型。

假设您有您的产品模型：

<?php

class Product extends Eloquent {

}

和您的产品详细信息模型：

<?php

class ProductDetail extends Eloquent {

}

所以你可以在它们之间建立关系

class Product extends Eloquent {

    public function details()
    {
       return $this->hasMany('ProductDetail');
    }

}

现在，如果您的控制器将模型列表传递给您的 UI：

public function index()
{
   return View::make('site.products')->with('products', Product::all());
}

在您的 UI 中，您将能够：

<ul>
    @foreach($products as $product)
        <li>
            <p>Product: $product->name</p>
            <p>Sizes:</p>
            <ul>
                @foreach($product->details as $detail)
                    <li>
                        {{$detail->size}}
                    </li>
                @endforeach
            </ul>
        </li>
    @endforeach
</ul>
