如何在Laravel 4中更新现有的雄辩关系? [英] How can I update an existing Eloquent relationship in Laravel 4?

问题描述

我正在尝试更新Laravel中一对多关系的关系.不幸的是我找不到任何文档.谁能帮我吗?

I am trying to update the relationship of a one-to-many relationship in Laravel. Unfortunately I couldn't find any documentation for it. Can anyone help me?

这是我到目前为止所拥有的:

This is what I have so far:

class Account extends Eloquent 
{
     public function users()
     {
         return $this->hasMany('User');
     }
}

class User extends Eloquent 
{
     public function account()
     {
         return $this->belongsTo('Account');
     }
}

现在，我尝试将USER(1)> ACCOUNT(50)的关系更新为USER(1)> ACCOUNT(99).我该怎么做?我尝试了以下方法:

Now I am trying to update the relationship from USER(1) > ACCOUNT(50) to USER(1) > ACCOUNT(99). How would I do this? I tried the following:

$account = Account::find(99);

User::find(1)->account()->save($account);

但这不起作用:-(任何帮助深表感谢！

But that doesn't work :-( Any help deeply appreciated!!

更新:

以下作品:

$user = User::find(1);
$user->account_id = 99;
$user->save();

...但是必须有一种更好的解决方案，对吗?

...but there MUST be a better solution like the one above, right?

它与save()和attach()方法在多对多关系中工作，以更新表之间的关系(从关系的两侧).在一对多关系中，似乎不支持attach()方法.

It works in many-to-many relationships with both the save() and attach() method to update the relationship between tables (from both sides of the relationship). In one-to-many relationships the attach() method doesn't seem to be supported.

推荐答案

泰勒·奥特威尔(Taylor Otwell)的官方答案如下:

Taylor Otwell's official answer is the following:

$account = Account::find(99);
User::find(1)->account()->associate($account)->save();

我在官方文档中找不到associate()方法.因此，如果有人正在寻找解决方案.来啦！

I couldn't find the associate() method in the official docs. So if someone else is looking for a solution to this. Here you go!
