Magento 2.2.5 : Save Catalog Rule Conditions

Question

I am trying to save catalog rule condtions from my custom module, below is the array I get in my controller save.php

[rule] => Array
    (
        [conditions] => Array
            (
                [1] => Array
                    (
                        [type] => Magento\CatalogRule\Model\Rule\Condition\Combine
                        [aggregator] => all
                        [value] => 1
                        [new_child] => 
                    )

                [1--1] => Array
                    (
                        [type] => Magento\CatalogRule\Model\Rule\Condition\Product
                        [attribute] => attribute_set_id
                        [operator] => ==
                        [value] => 4
                    )

            )

    )

The array is further modified to conditions by doing:

if (isset($data['rule'])) {
                $data['conditions'] = $data['rule']['conditions'];
                unset($data['rule']);
            }

My database table column for conditions is conditions_serialized as it is in catalogrule table. Now my question is what are the steps I am missing in between -- because when I save a record I get the error:

Something went wrong while saving the record !

Any one who has implemented this might be having a better insight in to the problem , please advise .

You have to use the loadPost function of the model.

$model->loadPost($data)->save();

An example is:

 /**
 * Save action
 *
 * @return \Magento\Framework\Controller\ResultInterface
 */
public function execute() {
    $data = $this->getRequest()->getPostValue();
    /** @var \Magento\Backend\Model\View\Result\Redirect $resultRedirect */
    $resultRedirect = $this->resultRedirectFactory->create();
    if ($data) {

        /** @var \Vendor\Module\Model\Example $model */
        $model = $this->_objectManager->create('Entrepids\Warranty\Model\Warranty');

        $id = $this->getRequest()->getParam('example_id');
        if ($id) {
            $model->load($id);
        }

        if (isset($data['rule'])) {
            $data['conditions'] = $data['rule']['conditions'];
            unset($data['rule']);
        }

        try {
            $model->loadPost($data)->save();                       
            $this->messageManager->addSuccess(__('You saved this warranty.'));
            $this->_objectManager->get('Magento\Backend\Model\Session')->setFormData(false);
            if ($this->getRequest()->getParam('back')) {
                return $resultRedirect->setPath('*/*/edit', ['warranty_id' => $model->getId(), '_current' => true]);
            }
            return $resultRedirect->setPath('*/*/');
        } catch (\Magento\Framework\Exception\LocalizedException $e) {
            $this->messageManager->addError($e->getMessage());
        } catch (\RuntimeException $e) {
            $this->messageManager->addError($e->getMessage());
        } catch (\Exception $e) {
            $this->messageManager->addException($e, __('Something went wrong while saving the warranty.'));
        }

        $this->_getSession()->setFormData($data);
        return $resultRedirect->setPath('*/*/edit', ['warranty_id' => $this->getRequest()->getParam('warranty_id')]);
    }
    return $resultRedirect->setPath('*/*/');
}
