Magento Module tutorial – Disabling the module
In the beginning we’ll learn to disable the module.
For completing the task, we need to run the following code:
php bin/magento module:disable Aspiration_Custom
So, instantly it’ll flag as disabled, if check the config.php file.
Let’s use a very interesting command. This command has the ability to execute the module uninstall script. So, it’ll simply delete the full module except the module installed by the composer.
Further, the code is following:
php bin/magento module:uninstall Inchoo_Custom
Magento Module tutorial – Set up classes
In general, there are 6 different setup classes inside the module in Mage 2. Here the classes are following:
Setup/UpgradeSchema
Setup/Recurring

upgrade-1.0.0-1.0.1.php upgrade-1.0.1-1.0.3.php install-1.0.0.php

Magento Module tutorial – Install & Upgrade
Therefore to do install & upgrade, we need Scheme setup scripts. As these setup scripts can change the database Schema. Also according to need they’re able to change or create database tables. In case we’re installing module, we need to execute the: Setup\InstallSchema::install() .
namespace Aspiration\Custom\Setup;
use Magento\Framework\Setup\InstallSchemaInterface;
use Magento\Framework\Setup\SchemaSetupInterface;
use Magento\Framework\Setup\ModuleContextInterface;
class InstallSchema implements InstallSchemaInterface
{
public function install(SchemaSetupInterface $setup, ModuleContextInterface $context)
{
$setup->startSetup();
$table = $setup->getConnection()->newTable(
$setup->getTable('inchoo_custom')
)->addColumn(
'custom_id',
\Magento\Framework\DB\Ddl\Table::TYPE_INTEGER,
null,
['identity' => true, 'unsigned' => true, 'nullable' => false, 'primary' => true],
'Custom Id'
)->addColumn(
'name',
\Magento\Framework\DB\Ddl\Table::TYPE_TEXT,
255,
[],
'Custom Name'
)->setComment(
'Custom Table'
);
$setup->getConnection()->createTable($table);
$setup->endSetup();
}
