Laravel 4:如何在Eloquent模型中更新多个字段? [英] Laravel 4: how to update multiple fields in an Eloquent model?

问题描述

如何在雄辩模型中更新多个字段?假设我是这样的:

How can I update multiple fields in an Eloquent model? Let's say I got it like this:

$user = User::where("username", "=", "rok");

然后我拥有所有这些模型参数:

And then I have all these model parameters:

$new_user_data = array("email" => "[e-mail]", "is_superuser" => 1, ...);

我不能只是做

$user->update($new_user_data);

正确的方法是什么?我希望不要foreach.

What's the proper way? I hope not a foreach.

但是，以下方法确实有效.这是要走的路吗?

The following does work, however. Is this the way to go?

User::where("id", "=", $user->id)->update($new_user_data);

最后一个问题(除了笨拙)是，从对象上下文使用它时，更新的字段在$this变量中不可见.

The problem with the last one (besides it being clunky) is that when using it from an object context, the updated fields are not visible in the $this variable.

推荐答案

您要查找的方法是fill():

$user = User::where ("username","rok"); // note that this shortcut is available if the comparison is =
$new_user_data = array(...);
$user->fill($new_user_data);
$user->save();

实际上，您可以执行$user->fill($new_user_data)->save();，但是我发现单独的语句更易于阅读和调试.

Actually, you could do $user->fill($new_user_data)->save(); but I find the separate statements a little easier to read and debug.
