如何正确隐藏模型关系，以免返回toArray()或toJson()? [英] How do I correctly hide model relationships from returning in toArray() or toJson()?

问题描述

我目前正在开发一个正在编写API的项目，并且在许多模型中，我试图隐藏它们的父级关系，就像这样

I'm currently working on a project where I'm writing an API, and with a lot of the models, I'm trying to hide their parent relationships from being returned, like so

<?php namespace Viper\Model;

class User_Token extends Eloquent {

    protected $table = 'users_tokens';

    protected $fillable = array(
        'user_id', 'token'
    );

    protected $hidden = array(
        'id', 'user_id', 'user'
    );

    public function user() {
        return $this->belongsTo('User');
    }

}

在Laravel文档中，对于 Eloquent>转换为数组或Json部分，其中明确指出

In the Laravel documentation, for the Eloquent > Converting to Array or Json section, it clearly says

注意:隐藏关系时，请使用关系的方法名称，不是动态访问者名称.

Note: When hiding relationships, use the relationship's method name, not the dynamic accessor name.

这到底是什么意思?在上面的示例中，方法名称和动态访问器名称都相同，并且我一辈子都想不到，请考虑一下情况并非如此.

What exactly does this mean? In the above example, both the method name and the dynamic accessor name are the same, and I can't for the life of me, think of a situation where this wouldn't be the case.

推荐答案

protected $hidden = array(
        'id', 'user_id', 'user'
                           ^^^ relationship's method name which is "user"
);

如果要隐藏关系，则必须在隐藏属性下包括方法名称.从隐藏属性中，我可以看到，您正在从Array和JSON conversion完美隐藏 user 关系.但是，如果您在 users_tokens 表中具有用户"列，则我不知道Laravel的行为.

if you want to hide the relationship , you have to include method name under hidden attributes. From your hidden attributes, i can see, you are perfectly hiding user relationship from Array and JSON conversion . However, if you have 'user' column in your users_tokens table, I have no idea what Laravel will behave.

public function user() {
    return $this->belongsTo('User');
}
