CRON with settings from multiple stores

Question

In Magento 2, what is the cleanest way to have the same CRON job run for every store, and pull relevant configuration settings from the appropriate store?

Would it be to add a loop inside Vendor/Module/Cron/Job.php, execute method, checking every store, and setting $this->storeManager->setCurrentStore at the top of the method?

Followed by,

$this->scopeConfig->getValue('...', \Magento\Store\Model\ScopeInterface::SCOPE_STORE)

Answer 1

Simply Inject the StoresConfig class in your Cron model class constructor, and read store config values with getStoresConfigByPath($path) for all stores. This will return the config values with the associated store ids:

Class File: /vendor/magento/module-store/Model/StoresConfig.php

public function getStoresConfigByPath($path)
{
    $stores = $this->_storeManager->getStores(true);
    $storeValues = [];
    /** @var $store \Magento\Store\Model\Store */
    foreach ($stores as $store) {
        try {
            $value = $this->_config->getValue($path, ScopeInterface::SCOPE_STORE, $store->getCode());
            $storeValues[$store->getId()] = $value;
        } catch (NoSuchEntityException $e) {
            // Store doesn't really exist, so move on.
            continue;
        }
    }
    return $storeValues;
}

Here is the following procedure to setup cron in Magento2 :

app/code/Vender/ModuleName/etc/cron_groups.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Cron:etc/cron_groups.xsd">
    <group id="cron_group_name">
        <schedule_generate_every>1</schedule_generate_every>
        <schedule_ahead_for>4</schedule_ahead_for>
        <schedule_lifetime>2</schedule_lifetime>
        <history_cleanup_every>10</history_cleanup_every>
        <history_success_lifetime>60</history_success_lifetime>
        <history_failure_lifetime>600</history_failure_lifetime>
    </group>
</config>

Create crontab.xml : app/code/Vendor/ModuleName/etc/crontab.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Cron:etc/crontab.xsd">
    <group id="cron_group_name">
        <job name="cronname_api" instance="Vendor\ModuleName\Cron\Cron" method="execute">
            <schedule>* * * * *</schedule>
        </job>
        .......................
        ......................
    </group>
</config>

Create Cron.php app/code/Vendor/ModuleName/Cron/Cron.php

  <?php
    namespace Vendor\ModuleName\Cron;

    class Cron
    {
    public function execute()
    {
    // Paste your logic for multiple stores
   // Given example cron will run every minute execute() function 
    }
        }
