Question

我有一组具有以下关系的产品模型：

OrderProduct-> AccountProduct->产品

OrderProduct模型属于AccountProduct，并且与产品具有hasOneThrough关系。这些关系可以正常工作，直到Im被帐户软件和产品已被软删除的情况下为止。我仍然可以通过链接来检索关系，但是hasOneThrough在这种情况下无法工作。

public function accountProduct(): BelongsTo
{
    return $this->belongsTo(AccountProduct::class)
        ->withTrashed();
}

public function product(): HasOneThrough
{
    return $this->hasOneThrough(
        Product::class,
        AccountProduct::class,
        'id',
        'id',
        'account_product_id',
        'product_id'
    )->withTrashed();
}

输出：

echo $orderProduct->accountProduct->product->id

"1"


echo $orderProduct->product

"Trying to get property ID of a non object"

在accountProduct和orderProduct都被软删除时，是否可以进行代码更改以使Eloquent返回HasOneThrough关系？

Laravel没有对此的本地支持。

我为此创建了一个包：https://github.com/staudenmeir/eloquent-has-many-deep

class OrderProduct extends Model
{
    use \Staudenmeir\EloquentHasManyDeep\HasRelationships;

    public function product(): HasOneThrough
    {
        return $this->hasOneDeep(
            Product::class,
            [AccountProduct::class],
            ['id', 'id'],
            ['account_product_id', 'product_id']
        )->withTrashed()
        ->withTrashed('account_products.deleted_at');
    }
}

雄辩的hasOneThrough withTrashed
