我有一个问题，我按日期过滤集合，但我希望得到的项目没有在集合中返回，但是如果我打印出集合使用的 SQL 并针对我的数据库运行该项目，则返回该项目。

$from = new \DateTime($lsDate);
$orders = $this->_orderCollectionFactory->create()
        ->addFieldToSelect(['grand_total', 'created_at'])
        ->addAttributeToFilter('created_at', array('gteq' => $from->format('Y-m-d H:i:s')))
        ->addAttributeToFilter('customer_id',$customer->getId())
        ->setPageSize(10)
        ->setOrder('created_at', 'desc');

$from->format('Y-m-d H:i:s') // Lets say this is 2019-08-06 15:33:00
$this->logger->info(count($orders)); // This is 0

SELECT `main_table`.`entity_id`, `main_table`.`grand_total`, `main_table`.`created_at` FROM `sales_order` AS `main_table` WHERE (`created_at` >= '2019-08-06 15:33:21')

 $newDate = new \DateTime();
 $customer->setCustomAttribute('ls_start_date', $newDate->format('Y-m-d H:i:s'));

$lsDate = $customer->getCustomAttribute('ls_start_date')->getValue();

最佳答案

首先，也许我们需要一个通用的 Magento 日期处理解释。

Magento 打算将其所有日期以格林威治标准时间保存在 DB 中。
这种设计选择的原因很简单:Magento 允许您配置可能位于多个时区的多商店。

假设我有一个有 3 家商店的 Magento，我确实在伦敦经营。
这是我的商店:

use Magento\Framework\Stdlib\DateTime\DateTimeFactory;
use Magento\Customer\Model\Customer;   

class CustomerLsDate {
    private $dateTimeFactory; 

    public function __construct(DateTimeFactory $dateTimeFactory) {
        $this->dateTimeFactory = $dateTimeFactory;
    }

    public function setLsDate(Customer $customer): CustomerLsDate {
        $customer->setCustomAttribute('ls_start_date', $this->dateTimeFactory->create()->gmtDate('Y-m-d H:i:s'));

        return $this;
    }
}

use Magento\Framework\Stdlib\DateTime\TimezoneInterface;
use Magento\Customer\Model\Customer;

class CustomerLsDate {
    private $timezone;

    public function __construct(TimezoneInterface $timezone) {
        $this->timezone = $timezone;
    }

    public function getLsDate(Customer $customer): string {
        $date = $this->timezone->date(
            new \DateTime(
                $customer->getCustomAttribute('ls_start_date')->getValue(),
                new \DateTimeZone('GMT')
            )
        );

        Zend_Debug::dump($date->format('Y-m-d H:i:s'));

        return $date->format('Y-m-d H:i:s');
    }  
}

use Magento\Framework\Stdlib\DateTime\DateTimeFactory;
use Magento\Framework\Stdlib\DateTime\TimezoneInterface;
use Magento\Customer\Model\Customer;   

class CustomerLsDate {
   private $dateTimeFactory; 
   private $timezone;

   public function __construct(DateTimeFactory $dateTimeFactory, TimezoneInterface $timezone) {
       $this->timezone = $timezone;
       $this->dateTimeFactory = $dateTimeFactory;
   }

   public function setLsDate(Customer $customer): CustomerLsDate {
       $customer->setCustomAttribute(
           'ls_start_date', 
           $this->dateTimeFactory->create()->gmtDate('Y-m-d H:i:s')
       );

       return $this;
   }

   public function getLsDate(Customer $customer): string {
       $date = $this->timezone->date(
           new \DateTime(
               $customer->getCustomAttribute('ls_start_date')->getValue(),
               new \DateTimeZone('GMT')
           )
       );

       Zend_Debug::dump($date->format('Y-m-d H:i:s'));
       return $date->format('Y-m-d H:i:s');
    }  
}

SET time_zone = '+00:00'; 
SELECT `main_table`.`entity_id`, `main_table`.`grand_total`, `main_table`.`created_at` FROM `sales_order` AS `main_table` WHERE (`created_at` >= '2019-08-06 15:33:21');

$date = new \DateTime('2019-08-06 15:33:21', new \DateTimeZone('Europe/London'));

echo $date->format('Y-m-d H:i:s'); // echoes 2019-08-06 14:33:21

$newDate = new \DateTime('now',new \DateTimeZone('GMT'));
$customer->setCustomAttribute('ls_start_date', $newDate->format('Y-m-d H:i:s'));

use Magento\Framework\Stdlib\DateTime\DateTimeFactory;    

class Whatever {
   private $dateTimeFactory; 

   public function __construct(DateTimeFactory $dateTimeFactory) {

   public function assignThatLsDate($customer) {
       $customer->setCustomAttribute('ls_start_date', $this->dateTimeFactory->create()->gmtDate('Y-m-d H:i:s'));

}

$newDate = new \DateTime();

$customer->setCustomAttribute('ls_start_date_timezone', $newDate->getTimezone ());

// query to your collection is unchanged
