安裝完mongodb的外掛，就可以使用mongodb了，但是，在插入和更新mongodb的資訊的時候，active record 會因為沒有型別，

不能對欄位自動的強制轉換型別，下面是強制轉換型別

使用demo

1.定義active record：

<?php

namespace myapp\code\core\Erp\Sales\models;
use common\extensions\mongodb\IActiveRecord;
 //  use myapp\code\core\Erp\Sales\models\Mongocustomer;
class Mongocustomer extends IActiveRecord
{
	
	# 定義collection name
    public static function collectionName()
    {
        return 'mongo_customer';
    }

	# 定義collection 各個欄位的型別定義，在儲存前進行型別轉換
	public function schema_columns(){
		# 不要定義  _id
		return [
			
			'name' 			=> 'String',  # String型別
			'email' 		=> 'String',
			'address' 		=> 'String',
			'status' 		=> 'Int',		# Int型別
			'age'			=> 'Int',
			'active'		=> 'Int',
			'image'			=> [
				'media'			=> 'String',
				'created_at' 	=> 	'DateTime',	#時間型別
				'gallery'		=>  ['String'],	# 字串陣列
			],
			'price'	=> [
				'en_price' => 'float',  # float型別
				'fr_price' => 'float',
			],
			'created_at'	=> 'datetime',  # datetime型別
			'custom_option' => [
				[
					'name' 			=> 'String',
					'sort_order' 	=> 'Int',
					'is_required'	=> 'Int',
					'data'			=> [
						[
							'title' => [
								'en_title' => 'String',
								'fr_title' => 'String',
								'de_title' => 'String',
								'ru_title' => 'String',
							],
							'price' => 'Float',
							'sort_order' => 'Int',
							
							
							
						],
					],
				],
			]
		];
	}



}

$Mongocustomer = new Mongocustomer();
		$Mongocustomer->name = 1;
		$Mongocustomer->created_at = '2015-01-01';
		$Mongocustomer->custom_option = [
			[
				'name' => 'color',
				'sort_order' => '2',
			],
			[
				'name' => 'size',
				'data' => [
					[
						'title' => [
							'en_title' => 'l',
							'fr_title' => 'l',
						],
						'price' => '12.22',
					],
					
					[
						'title' => [
							'en_title' => 'en_m',
							'fr_title' => 'fr_m',
						],
						'price' => '13.22',
					],
				],
			],
		];
		$Mongocustomer->image = [
			'media' 	=> 22,
			'gallery' 	=> [11,22,33,44,55],
		];
		$Mongocustomer->save();

儲存完成後，看結構：

可以看到結果被強制轉換了。

$data = Mongocustomer::find()->asArray()->all();
		foreach($data as $d){
			echo Mongocustomer::getDateTime($d['created_at']);
			echo "<br/>*********<br/>";
		}
		exit;

呼叫3：更新：

$dd = Mongocustomer::findOne(['_id'=>45]);
		$dd->name = 4444;
		$dd->save();
		var_dump($dd);
		exit;

1._id 是類似mysql的id遞增方式

2.如果一個定義的沒有key的陣列，會增加生成的mongodb的_id

3.定義的欄位都會強制轉換。

4.Mongocustomer::getDateTime($d['created_at']);  可以轉換時間格式。
