我真的很难让 OctoberCMS 关系在我正在编写的插件中工作。我有两个表:products 和 product_images。products 和 product_images 之间存在一对多的关系。

在我的产品模型中,我有:

public $hasMany = [
    'product_images' => ['Bt/Shop/Models/ProductImages']
];

我有一个名为 ProductImages 的模型,位于 plugins/bt/shop/models/ProductImages.php 中。模型定义为:

<?php namespace Bt\Shop\Models;

use Model;

class ProductImages extends Model
{
    public $table = 'bt_shop_product_images';

    protected $dates = ['published_at'];

    public static $allowedSortingOptions = array(
        'name asc' => 'Name (ascending)',
        'name desc' => 'Name (descending)',
        'updated_at asc' => 'Updated (ascending)',
        'updated_at desc' => 'Updated (descending)',
        'published_at asc' => 'Published (ascending)',
        'published_at desc' => 'Published (descending)',
    );

    public $preview = null;

    public $belongsTo = [
        'products' => ['Bt/Shop/Models/Products']
    ];

    ...

我的 Products 模型的定义如下所示:

<?php namespace Bt\Shop\Models;

use Model;

class Products extends Model
{

    public $table = 'bt_shop_products';

    protected $dates = ['published_at'];

    public static $allowedSortingOptions = array(
        'name asc' => 'Name (ascending)',
        'name desc' => 'Name (descending)',
        'updated_at asc' => 'Updated (ascending)',
        'updated_at desc' => 'Updated (descending)',
        'published_at asc' => 'Published (ascending)',
        'published_at desc' => 'Published (descending)',
    );

    public $preview = null;

    public $hasMany = [
        'product_images' => ['Bt/Shop/Models/ProductImages']
    ];

我得到的错误是:

找不到类“ProductImages”

/var/www/mysite/public/vendor/october/rain/src/Database/Model.php 第 772 行

我相信在定义 Product hasMany 关系时,代码不知何故不知道 ProductImages 类。Model.php 中的代码,第 772 行是:

public function hasMany($related, $primaryKey = null, $localKey = null, $relationName = null)
{
    if (is_null($relationName))
        $relationName = $this->getRelationCaller();

    $primaryKey = $primaryKey ?: $this->getForeignKey();
    $localKey = $localKey ?: $this->getKeyName();
    $instance = new $related;

    return new HasMany($instance->newQuery(), $this, $instance->getTable().'.'.$primaryKey, $localKey, $relationName);
}

在我的例子中,名为 $related 的变量等于 Bt/Shop/Models/ProductImages。我打印出来确定。

有什么建议么?

我解决了。我在我的 belongsTo 和 hasMany 定义中使用了正斜杠而不是反斜杠:

旧(坏):

public $belongsTo = [
    'products' => ['Bt/Shop/Models/Products']
];

新的(工作):

public $belongsTo = [
    'products' => ['Bt\Shop\Models\Products']
];

干杯,布雷特
