Magento 2 Edit Catalog Rule conditions in UI Form

Question

I have created a UI form with field catalog rule conditions. The form loads display the conditions section and it is saved in the table. But in edit case the conditions are not displayed.

Reference: https://www.mageworx.com/blog/2016/09/magento-2-module-with-conditions-model-fieldset/

Please help me to resolve this. Here is my code

Installschema.php

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

        $table = $installer->getConnection()->newTable(
            $installer->getTable('example_label')
        )->addColumn(
            'label_id',
            \Magento\Framework\DB\Ddl\Table::TYPE_SMALLINT,
            null,
            ['identity' => true, 'nullable' => false, 'primary' => true],
            'ID'
        )->addColumn(
            'name',
            \Magento\Framework\DB\Ddl\Table::TYPE_TEXT,
            255,
            ['nullable' => false],
            'Name'
        )->addColumn(
            'conditions_serialized',
            Table::TYPE_TEXT,
            '4G',
            [],
            'Conditions Serialized'
        )->addIndex(
            $installer->getIdxName('example_label', ['name']),
            ['name']
        )->setComment('example_label Table');
        $installer->getConnection()->createTable($table);

     }

Answer 2

Try with below way :

In your data provider file set condition field value like below.

Vendor\ProductLabel\Model\ResourceModel\Productlabel\DataProvider

 "conditions_serialized_field" => $collectionData->getData('conditions_serialized_field')

I hope it works!
