端口StdClass数据到模型 [英] Port StdClass data to Model

问题描述

问题是如下：

1）数据库中的几个表中有数百万行，所以使用Eloquent并不有效，因为我也有多重关系在这种情况下，解决方案是编写自定义DB :: raw（）选择和连接以有效地完成任务。这可以返回一个StdClass，你可能会知道。

1) I have millions of rows in a few tables in the database, so using Eloquent is not efficient, as I have also multiple relationships. The solution in this case was to write custom DB::raw() selects and joins to accomplish the tasks efficiently. This returns a StdClass as you may know.

2）我有4-5个模型有相当冗长的方法，我需要使用，所以最好的解决方案要为StdClass的每一行创建这些模型的实例，然后使用这些方法。

2) I have 4-5 models that have quite lengthy methods, which I need to use, so a best possible solution would be to create instances of those models for each row of the StdClass, and then use those methods.

是否有一个已知的最佳做法，用于移植信息StdClass进入模型，在OOP模式方面？你会怎么解决这个问题？我会采取任何建议，我准备好重新编码。

Is there a known 'best practice' for 'porting' the info from the StdClass into the models, in terms of OOP patterns? How would you guys tackle this problem? I would take any suggestions, I am ready to even restructure the code.

推荐答案

这样的事情会适合你。只需调整它的需求：

Something like this will work for you. Just adjust it to your needs:

public function newFromStd(stdClass $std)
{
    // backup fillable
    $fillable = $this->getFillable();

    // set id and other fields you want to be filled
    $this->fillable(['id', ... ]);

    // fill $this->attributes array
    $this->fill((array) $std);

    // fill $this->original array
    $this->syncOriginal();

    $this->exists = true;

    // restore fillable
    $this->fillable($fillable);

    return $this;
}

那么你可以这样做：

$user = with(new User)->newFromStd( DB::table('users')->first() );

// or make it static if you like:
$user = User::newFromStd( DB::table('users')->first() );
