Laravel Eloquent Serialization:如何重命名属性?

2021-12-26 00:00:00 php laravel eloquent

例如，我有扩展 Eloquent 的用户模型.在数据库表中，列名是user_id.

For example, I have User model extending Eloquent. In the database table, the column name is user_id.

阅读后如何将结果输出为'userId'?

How do I output the result as 'userId' after reading?

推荐答案

使用属性访问器添加单个别名"

您可以使用属性访问器来创建新属性":

public function getUserIdAttribute(){
    return $this->attributes['user_id'];
}

这允许您以这种方式访问​​值:$user->userId

This allows you to access the value this way: $user->userId

现在让我们将值添加到数组/JSON 转换中:

Now let's add the value to array / JSON conversion:

protected $appends = array('userId');

最后隐藏丑陋的user_id:

protected $hidden = array('user_id');


在将模型转换为数组或 JSON 字符串时，您还可以使用 toArray() 更改所有属性名称.

You can also use toArray() to change the all attribute names when converting the model into an array or JSON string.

public function toArray(){
    $array = parent::toArray();
    $camelArray = array();
    foreach($array as $name => $value){
        $camelArray[camel_case($name)] = $value;
    }
    return $camelArray;
}
