Changes to module not reflected to magento

[kornblumenapo]

Hi,

I have written a small module myself. It is quite buggy, so I change every now and then some lines in the source code.

After changing the source, the change works for exactly one time, then the changes do not work any more and it seems that the old code is used once again. When I then edit the source again (the source is still the source AFTER the changes), w.g. when I insert a blank line, same behaviour: One single time new code, then old code.

Any hints from you?

Regards,
Gunther

Hi @kornblumenapo,

Maybe you need to recompile the code?

https://devdocs.magento.com/guides/v2.2/config-guide/cli/config-cli-subcommands-compiler.html

On which mode are you executing the store/code? https://devdocs.magento.com/guides/v2.2/config-guide/cli/config-cli-subcommands-mode.html

Hi @kornblumenapo

i understand the problem you are facing !!

Generally in magento 2 when we are using factory method or any generation/proxy classes in our custom module , we must required to compile our code again and again !

or another option is we need to remove generated, var/generation directory from the magento 2 root folder. as factory and proxy classes are generating each and every time when you load module or you compile module !

So here whatever the problem you are facing - its because of compilation only.

if you change anything related to those classes you required to run below commands :

php bin/magento setup:di:compile
php bin/magento cache:clean
php bin/magento cache:flush

 
Hope it helps !

Hello @kornblumenapo

If you are doing development then disable compilation first.

Then remove generated/generation and  generated/matadata

Then check it.

Hope it will help you.

still the same problem... strange behaviour...

Here's the code:

if (!$order->getShipmentsCollection()) 
			{
					$this->messageManager->addError("There are no printable Shipment related to selected orders ".$order->getIncrementID());
					//echo ("NOT FOREACH");
			}
			else
			{
				$this->messageManager->addNotice("PZ enter:".$order->getIncrementID());
				
				foreach ($order->getShipmentsCollection() as $shipment) 
				{
					$document = $shipmentDocumentFactory->create(
						['data' => ['shipment' => $shipment]]
					);
					//echo ("FOREACH");

					$pdfRenderer->addDocument($document);
					$this->messageManager->addNotice("PZ OK für:".$order->getIncrementID());
				}
			}

It seems there is a problem in my code:
Magento enters the else branch, but foreach is not executed or only executed some times.
Any ideas?
