Flushing the Magento 2 Cache Storage
You can easily flush the cache storage of Magento 2 from the command line. Note that the following script must be executed from the Magento 2 root folder:
|
1 2 |
find var/* -type f -or -type d | grep -v 'session' | xargs rm -rf && \ rm -rf pub/static/* |
It deletes all content from the var subfolder excluding the.htaccess file and the var/session subfolder. Besides, the script also deletes all content from the pub/static subfolder excluding the.htaccess file.
Writing a message to a system log in Magento 2
To create a message to a system log in Magento 2.0, use the code listed below:
|
1 2 3 4 |
\Magento\Framework\App\ObjectManager::getInstance() ->get('Psr\Log\LoggerInterface') ->debug('message') ; |
In Magento 1, for instance, this code was more simple:
|
1 |
Mage::log('message'); |
but you can also utilize another approach in case of Magento 2. Since there is a _logger property related to many objects, you can perform the same task by calling inside such objects. Just use the following code:
|
1 |
$this->_logger->debug('message'); |
Please note that not every object has the _logger property. Thus, this method will not work with all your objects.

/** * @category Genmato * @package Genmato_MageStackProduct * @copyright Copyright (c) 2015 Genmato BV (https://genmato.com) */ namespace Genmato\DemoProduct\Model\Product\Type; class Demo extends \Magento\Catalog\Model\Product\Type\AbstractType { /** * Delete data specific for Simple product type * * @param \Magento\Catalog\Model\Product $product * @return void */ public function deleteTypeSpecificData(\Magento\Catalog\Model\Product $product) { } } |
