Magento 2. Add attribute to Catalog Price Rule

Question

Is it possible to add additional (simple string) attribute to the Catalog Price Rule? If it is, please, tell about it in details. Better with working code example.

[UPD]

I mean add attribute to the price rule itself.

Answer 1

It is pretty easy to do this in Magento 2.1. You need to add a row to the catalogrule table using the module (in your own module):

app/code/Vendor/Rules/Setup/InstallSchema.php

namespace Vendor\Rules\Setup;

use Magento\Framework\Setup\InstallSchemaInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\SchemaSetupInterface;

class InstallSchema implements InstallSchemaInterface
{

    public function install(SchemaSetupInterface $setup, ModuleContextInterface $context)
    {
        $installer = $setup;
        $installer->startSetup();

        $installer->getConnection()->addColumn(
            $installer->getTable('catalogrule'),
            'test_column',
            [
                'type' => \Magento\Framework\DB\Ddl\Table::TYPE_TEXT,
                'length' => 32,
                'nullable' => false,
                'default' => '',
                'comment' => 'Test Column'
            ]
        );

        $installer->endSetup();
    }
}

Then, add a UI form update to the catalog rule form in your module:

app/code/Vendor/Rules/view/adminhtml/ui_component/catalog_rule_form.xml

<?xml version="1.0" encoding="UTF-8"?>
<form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
    <fieldset name="rule_information">
        <field name="test_column">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="label" xsi:type="string">Test Column</item>
                    <item name="visible" xsi:type="boolean">true</item>
                    <item name="dataType" xsi:type="string">text</item>
                    <item name="formElement" xsi:type="string">input</item>
                    <item name="source" xsi:type="string">catalog_rule</item>
                    <item name="dataScope" xsi:type="string">test_column</item>
                    <item name="sortOrder" xsi:type="number">50</item>
                    <item name="validation" xsi:type="array">
                        <item name="required-entry" xsi:type="boolean">true</item>
                    </item>
                </item>
            </argument>
        </field>
    </fieldset>
</form>

The result will be the following:

Data save will be working on default:

You can add your own fieldset with fields in the same way.

You can copy entire catalog_rule_form.xml to your ui_component, clean cache and done.

Here is my file path magento2-root/src/app/code/Love/OneRoom/view/adminhtml/ui_component/catalog_rule_form.xml
