我正在尝试使用Eloquent获取表的所有行,其中ID不在数组$ids
中。
$product_deleteds = $category->products()->whereNotIn('id', $ids)->get();
我收到了这个错误:
SQLSTATE [23000]:完整性约束违规:1052 where子句中的列'id'不明确
请求产生的是:
Select *
from `products`
inner join `products_categories` on `products_categories`.`id` = `products`.`product_category_id`
where `products`.`deleted_at` is null
and `products_categories`.`restaurant_id` = 1
and `id` = 4 limit 1
我知道我可以这样提出要求:
$product_deleteds = $category->products()->whereNotIn('products.id', $ids)->get();
但我不想要,因为表的名称可能会改变。我也可以这样做,但似乎有点棘手:
$product_deleteds = $category->products()->whereNotIn(Product::getTableName().'.id', $ids)->get();
任何帮助?
答案 0 :(得分:2)
首先,你不能这样做:
$product_deleteds = $category->products()->whereNotIn(
Product::getTableName() // no such method and definitely not static, unless you create one
.'.id', $ids)->get();
但你可以这样做,以避免硬编码:
$relatedKey = $category->products()->getRelated()->getQualifiedKeyName();
$product_deleteds = $category->products()->whereNotIn($relatedKey, $ids)->get();
