Unable to use custom source_model

[supportopeadb2]

Hello,

I'm trying to create one custom source_model but getting the error "Class Demo\Test\Model\Config\Source\custom does not exist". 

In system.xml, we have added below code:

<field id="test" translate="label" type="select" sortOrder="1" showInDefault="1" showInWebsite="1" showInStore="1">
<label>Test</label>
<source_model>Demo\Test\Model\Config\Source\custom</source_model>
</field>

And our file app\code\Demo\Test\Model\Config\Source\Custom.php contain below code:

<?php
namespace Demo\Test\Model\Config\Source;

class custom implements \Magento\Framework\Option\ArrayInterface
{
public function toOptionArray()
{
return [
['value' => 'test', 'label' => __('test')],
['value' => 'demo', 'label' => __('demo')]
];
}
}

Can some one let me know what is wrong with this code.

Thanks!

Hi @supportopeadb2 

Please use the below code and let me know in case you face any issues.

<field id="test" translate="label" type="select" sortOrder="1" showInDefault="1" showInWebsite="1" showInStore="1">
   <label>Test</label>   <source_model>Demo\Test\Model\Config\Source\Custom</source_model>
</field>

Then create this file Demo\Test\Model\Config\Source\Custom.php

namespace Demo\Test\Model\Config\Source;

class Custom implements \Magento\Framework\Data\OptionSourceInterface
{
 public function toOptionArray()
 {
  return [
    ['value' => 'grid', 'label' => __('Grid Only')],
    ['value' => 'list', 'label' => __('List Only')],
    ['value' => 'grid-list', 'label' => __('Grid (default) / List')],
    ['value' => 'list-grid', 'label' => __('List (default) / Grid')]
  ];
 }
}

Replace custom with Custom and use the modified code.

Thank you.

Hi @supportopeadb2 

Can you please try deleting the generated folder and then use the below command to flush the cache.

php bin/magento cache:flush

Also when you are checking on admin please log out first and then again try to check after login.

Let me know in case you face any issues.

Thank you.
