下午好。
我正在尝试使用一种方法在 laravel 中上传多个图像，但它不能完全工作。
我遇到的问题是因为我有一个表文件，我将在其中注册与名为属性的表相关的上传图像。
产生的错误如下:
Connection.php 第 729 行中的 2/2 QueryException:
SQLSTATE[23000]:完整性约束违规:1452 无法添加或更新子行:外键约束失败(erpinmobiliaria.files，CONSTRAINT files_property_id_foreign FOREIGN KEY (property_id) REFERENCES properties (id) ON DELETE CASCADE) (SQL: insert into files ( 名称、updated_at、created_at)值(5844676fdd1e8.jpg，2016-12-04 18:58:55，2016-12-04 18 :58:55))
这是一堆错误:

最佳答案
您正在数据库中创建一个文件条目，但未在新记录中分配先前创建的属性 ID。
您的数据库由名称和 property_id 字段组成。您仅保存名称字段。
$image = File::create([
'name' => $filename,
'property_id => $properties->id
]);
