【中文标题】Connection.php 第 729 行中的 QueryException：SQLSTATE[23000]：Laravel 5.2

【英文标题】：QueryException in Connection.php line 729: SQLSTATE[23000]: Laravel 5.2

【发布时间】：2017-04-19 03:58:46

【问题描述】：

下午好。

我正在尝试使用一种方法在 laravel 中上传多张图片，但它不能完全正常工作。

我遇到的问题是因为我有一个表格文件，我将在其中注册我上传的与名为属性的表格相关的图像。

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 (@987654326 @) ON DELETE CASCADE) (SQL: insert into files (name, 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：

【参考方案1】：

您正在向数据库中创建文件条目，但未在新记录中分配先前创建的属性 ID。

您的数据库由 name 和 property_id 字段组成。您只保存了一个名称字段。

 $image = File::create([ 
            'name'      => $filename,
            'property_id => $properties->id

        ]);

非常感谢，我有点困惑，但您的回答和评论是正确的，它帮助我解决了这个错误。
