Two options to get the connection credentials for the environment’s deployed services are to run the magento-cloud relationships CLI command and to connect to the server via SSH and read $_ENV[‘services’] variable. The magento-cloud relationships CLI command displays information about the relationships between an environment and its services, such as database,cache, search, etc. The developer can use this command to get the connection data for each service in JSON format. Alternatively, the developer can connect to the server via SSH and read the $_ENV[‘services’] variable, which contains the same information as the CLI command output.

The developer can resolve this issue by creating a plugin for theMagento\Catalog\Model\Indexer\Product\Price::executeRow()method. This method is responsible for updating the product price index.

The plugin can be used to add the pricing adjustment from the database to the product price index. Once the product price index is updated, the layered navigation will display the correct price.

Here is an example of a plugin for theexecuteRow()method:

PHP

class MyPlugin

{

public function executeRow(

\Magento\Catalog\Model\Indexer\Product\Price $subject,

\Magento\Catalog\Model\Product $product,

array $data

) {

$adjustment = $this->getAdjustment($product);

$product->setPrice($product->getPrice() + $adjustment);

}

private function getAdjustment(Product $product)

{

$adjustment = $product->getData('adjustment');

if (!is_numeric($adjustment)) {

return 0;

}

return $adjustment;

}

}

This plugin will add theadjustmentdata from the product to the product price index. Once the product price index is updated, the layered navigation will display the correct price.

The developer can use the canInvoice method of the order object to check if the order can be invoiced or not. This method returns true if the order has a state of new, processing, or payment review and has not been fully invoiced yet. The developer can use this method in a conditional statement to send the order ID to the ERP system only if the order can be invoiced.

According to the Declarative Schema Overview guide for Magento 2 developers, declarative schema is a new feature that allows developers to declare the final desired state of the database and has the system adjust to it automatically, without performing redundant operations. However, declarative schema does not support uninstalling modules or reverting changes. To remove a table when a module is disabled, the developer needs to add a schema patch that implements Magento\Framework\setup\Patch\PatchRevertabieinterface and drops the table in the revert function. The revert function will be executed when the module is disabled using bin/magento module:disable command.
