Yii2 覆盖 find() 以全局添加默认条件 [英] Yii2 Override find() to add default condition globally

问题描述

我必须使用

namespace common\models;
use Yii;
use yii\db\ActiveQuery;

class Addfindcondition extends ActiveQuery
{

    public function init()
    {

        $this->andOnCondition([$this->modelClass::tableName() . '.branch_id' => Yii::$app->user->identity->branch_id ]);
        parent::init();
    }
}

并像这样分别调用每个模型中的方法

And call the method in each model separately like this

public static function find()
{
    return new Addfindcondition(get_called_class());
}

现在我想全局覆盖 find 方法.我怎么可能不需要在每个模型中使用这个静态方法

Now I want to override the find method globally. How it is possible that I dont need to use this static method in each model

推荐答案

您可以在 ActiveRecord 模型的情况下覆盖 find() 方法，因为您需要添加这对于所有模型你应该创建一个 BaseModel 说

You can override the find() method in case of ActiveRecord models, as you need to add this for all models you should create a BaseModel say

common\components\ActiveRecord 或在您的模型中(如果您愿意)

common\components\ActiveRecord or inside your models if you like

<?php
namespace common\components;
use yii\db\ActiveRecord as BaseActiveRecord;

class ActiveRecord extends BaseActiveRecord{
    public static function find() {
       return parent::find ()
        ->onCondition ( [ 'and' ,
            [ '=' , static::tableName () . '.application_id' , 1 ] ,
            [ '=' , static::tableName () . '.branch_id' , 2 ]
        ] );
    }
}

然后扩展你所有需要在find()方法中添加这个条件的模型，将yii\db\ActiveRecord替换为common\components\ActiveRecord 例如，如果我有一个 Product 模型并且我想默认添加条件，我将从

And then extend all your models where you need to add this condition to the find() method, replace yii\db\ActiveRecord to common\components\ActiveRecord for instance if I have a Product Model and I want to add the conditions to it by default I will change the model from

<?php

namespace common\models;

use Yii;

class Product extends yii\db\ActiveRecord {

到

<?php

namespace common\models;

use Yii;

class Product extends common\components\ActiveRecord{
