主义/ Symfony如何使用数组中的特定数据更新实体 [英] Doctrine/Symfony how to update entity with specific data from array

问题描述

我走了很久没有运气。我的情况是我有一个较大的表+60列，该列以 Doctrine实体表示。在FosREST上工作，我想要实现的是我想发送包含特定数据的JSON，例如

I have looking around for too long with no luck. My situation is that i have a bit large table +60 columns which is represented in Doctrine Entity. Working on FosREST and what i want to achieve is that i want to send a JSON with specific data let's say for example

[phone] => new_phone
[name] => new_name
[id] => 1

而我说该实体包含60多个列，例如地址，图片，类别等。

while like i said the entity contains over 60 columns like address, picture, category, etc...

和电话，姓名和ID并不是我每次都要更改的内容，但我想每次更改一些列。
因此，有时我可能想更新手机并命名，而第三次我想更改类别，我想更改类别和照片并指定地址
，所以有这样的东西吗？

and the phone, name and id are not what I want to change every time but i want to change some columns each time. So at some time i might want to update phone and name other time i want to change the category third time i want to change category and photo and address so is there anything like this ?

$entity->update($parameters);

其中的$参数如前所述动态变化。
ps。我知道我可以使用类似的东西构建一个很长的函数

where the $parameters are dynamically changed as explained before. ps. i know that i can build a very long function with something like

if(isset($parameters['name']){
     $entity->setName($parameters['name']);
}

但如果有60个ifs，这听起来像是愚蠢的话，还有其他方法吗？
谢谢

but with 60 ifs this just sounds idiotic anyone have any other approach ? Thanks

推荐答案

1）如果参数是根据属性命名的（此处带有下划线注释），则可以执行此操作

1) If the parameters are named after the attributes (here with underscore annotations), you can do this

use Doctrine\Common\Util\Inflector;
// ...

public function setParameters($params) {
    foreach ($params as $k => $p) {
        $key = Inflector::camelize($k);
        if (property_exists($this, $key)) {
            $this->$key = $p;
        }
    }
    return $this;
}

2）与二传手相同的事情

2) Same thing with the setters

use Doctrine\Common\Util\Inflector;
// ...

public function setParameters($params) {
    foreach ($params as $k => $p) {
        $key = Inflector::camelize($k);
        if (property_exists($this, $key)) {
            $this->{'set'.ucfirst($key)}($p); // ucfirst() is not required but I think it's cleaner
        }
    }
    return $this;
}

3）如果名称不同，则可以执行以下操作：

3) If its not the same name, you can do this :

public function setParameters($params) {
    foreach ($params as $k => $p) {
        switch $k {
            case 'phone':
                $this->phoneNumber = $p;
                break;
            // ...
        }
    }
    return $this;
}

编辑：最好的方法是第二个方法，但您应该定义一个白名单或列入黑名单，以避免用户更新您不希望他进行的操作。

EDIT : Best approach is number two but you should define a white-list or a black-list in order to avoid the user updating something you don't want him to.
