问题描述
在laravel 5.2中遇到了问题.
Got stuck in a issue with laravel 5.2.
以下是雄辩的创建操作(调用后)中的错误，
Following is the error during eloquent create operation(post call),
Model.php 453中的质量分配异常:column_name
Mass Assignment Exception in Model.php 453: column_name
以下是要考虑的先决条件:
Following are the prerequisites, which are to be taken into consideration:
- 模型中的可填写内容通过以下代码动态填充:
- Fillables in model are filled in a dynamic manner by the following code:
public function __construct() {
$this->fillable(\Schema::getColumnListing($this->getTable()))
}
以下是到目前为止调试的方法:
Following are the methods which are debugged till now:
-
在插入之前，在控制器中的$ model :: getillableField()中会给出适当的可填充数组.
Before insertion, in controller, $model::getillableField(), gives proper fillable array.
在model.php第450行中，
In model.php line(450),
if ($this->isFillable($key)) {
$this->setAttribute($key, $value);
}
上面的代码返回值为"false"，并且$ model :: getFillableField()在数组列表中具有column_name.
the above code returns the value as "false" and $model::getFillableField() has the column_name in the array list.
使用表的列对$ fillable变量进行硬编码可消除该错误.请帮忙，我哪里出问题了，解决方案是什么?
Hardcoding $fillable variable with columns of table removes the error.Please Help, where i am going wrong and what is the solution for it?
谢谢.
推荐答案
您真正想做的是使 ALL 字段可填充.
What you are really trying to do is make ALL fields fillable.
在Laravel中执行此操作的正确方法是:
The correct way to do this in Laravel is this:
protected $guarded = [];
即使在5.3中找到了它的文档，它也可以在5.2中使用.
This works in 5.2, even though the documentation for it is found in 5.3.
(相关源代码对于5.2 )
( 5.3版本的文档):
通过将$guarded设置为一个空数组，您将创建一个空的黑名单，从而允许对所有字段进行批量分配.
By setting $guarded to an empty array, you are creating an empty black list, allowing all fields to be mass assignable.
此外，如果此模型是 ever ，将直接根据用户输入进行构建，请不要这样做.由于某种原因，Laravel需要定义$fillable或$guarded.除非您的模型具有从字面上看是采用公共形式的1:1的字段，否则在批量分配时允许所有字段都可写是一个安全漏洞.
Also, if this model is ever going to be constructed directly from user input, please do not do this. Laravel requires either $fillable or $guarded to be defined for a reason. Unless your model has fields that are literally 1:1 with a public form, then allowing all fields to be writable on mass assignment is a security vulnerability.
