Yii2 在保存时修剪所有内容 [英] Yii2 trim everything on save

问题描述

Yii2 框架.为通用模型创建通用行为的想法:

Yii2 framework. The idea to create common behavior for common model:

• 在验证之前修剪模型中的所有字段.

• 如果是数组，则修剪数组中的所有值.

• before Validate trims all fields in model.

• if it's array trim all values in array.

1. 我想知道为什么在 Yii2 核心中不存在这种可能性.或者我错了.我是吗?

1. I'm wondered why in Yii2 core doesn't exist such possibility. Or I'm wrong. Am I?

如果我修剪所有字段，我会遇到什么问题?

What problems could I face if I trim all fields?

推荐答案

您可以创建行为并将其附加到您的模型中.

You can create a behavior and attach it at your models.

1) 在 common/components 中创建行为 TrimBehavior.

1) Create the behavior TrimBehavior in common/components.

<?php

namespace commoncomponents;

use yiidbActiveRecord;
use yiiaseBehavior;

class TrimBehavior extends Behavior
{

    public function events()
    {
        return [
            ActiveRecord::EVENT_BEFORE_VALIDATE => 'beforeValidate',
        ];
    }

    public function beforeValidate($event)
    {
        $attributes = $this->owner->attributes;
        foreach($attributes as $key => $value) { //For all model attributes
            $this->owner->$key = trim($this->owner->$key);
        }
    }
}

2) 在您的模型中添加以下内容:

2) In your models add the following:

//...
use commoncomponentsTrimBehavior;
//...

/**
 * Returns a list of behaviors that this component should behave as.
 *
 * @return array
 */
public function behaviors()
{
    return [
        [
            'class' => TrimBehavior::className(),
        ],
    ];
}

修剪属性取决于业务逻辑.如果你真的需要它，那没关系.

Trimming attributes it depends on business logic. If you really need it then it's ok.
