Custom Console command creation error in Magento 2

Question

I am creating console command to input values into the database, there is some argument missing an error. I have gone through several tutorials but to me, the code looks fine. The error is:

Not enough arguments (missing: "Credit, Amount has been credited").

Here is Console Class:

use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputArgument;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use Vendor\Module\Model\AmountFactory;

class AddItem extends Command
{
const INPUT_KEY_ACTION = 'Credit';
const INPUT_KEY_REFERENCE = 'Amount has been credited';
//const INPUT_KEY_AMOUNT = 50;

private $amountFactory;

public function __construct(AmountFactory $amountFactory)
{

  $this->amountFactory = $amountFactory;
  parent::__construct();

}

protected function configure()
{

   $this->setName('example:credit:refund')
   ->addArgument(
    self::INPUT_KEY_ACTION,
    InputArgument::REQUIRED,
    'Action name'
   )->addArgument(
    self::INPUT_KEY_REFERENCE,
    InputArgument::REQUIRED,
    'Action Reference'
   );
   //$this->setDescription('Demo console command');

   parent::configure();
   }
protected function execute(InputInterface $input, OutputInterface $output)
  {
   $amount = $this->amountFactory->create();
   $amount->setAction($input->getArgument(self::INPUT_KEY_ACTION));
   $amount->setReference($input->getArgument(self::INPUT_KEY_REFERENCE));
   //$amount->setAmount($input->getArgument(self::INPUT_KEY_AMOUNT));
   $amount->setIsObjectNew(true);
   $amount->save();
   return Cli::RETURN_SUCCESS;
 }
 }

In di.xml:

<type name="Magento\Framework\Console\CommandList">
   <arguments>
       <argument name="commands" xsi:type="array">
           <item name="rhinosCredit" xsi:type="object">Vendor\Module\Console\Command\AddItem</item>
       </argument>
   </arguments>

When I uncomment lines for third argument i.e Amount I get error

The "50" argument does not exist.

Can somebody help to figure out this error? Thank you

Answer 1

Your Argument Names are wrong, they should not be with space. for your case you have used

const INPUT_KEY_REFERENCE = 'Amount has been credited';

it should be like this

const INPUT_KEY_REFERENCE = 'amount_has_been_credited';

ALso in command you need to share the agruments

example:credit:refund ARG1 ARG2

Answer 2

In your configure() function add your argument AMOUNT for amount :

->addArgument(self:: INPUT_KEY_AMOUNT,InputArgument::REQUIRED,'Action Amount');
