module not saved in the database

Question

I created a ui component, but I have no idea how to save it in the database. I know I have to pass it to the controller for it to pass to the model but I don't know how my controller should be, here's my code:

form ui component:

 <dataSource name="novo_desconto_data_source">
        <argument name="dataProvider" xsi:type="configurableObject">
            <argument name="class" xsi:type="string">Vendor\Desconto\Model\DataProvider</argument>

Answer 1

if you have multiple fieldsets happened to me that i had to set them "manually" like:

$rawData->setEmployeeName($data['employee_details']['employee_name']);

or if you have a plain form without tabs this should do the trick:

$rawData->setData($data);

You create a save action controller where you call your modelFactory witch create's or uses the current 'entity_id' to overwrite or create a new row.

Your controller should look like this,

<?php
    
    
    namespace Vendor\Module\Controller\Adminhtml\Employee;
    
    
    class Save extends \Magento\Backend\App\Action
    {
        var $employeeFactory;
    
    
        public function __construct(
            \Magento\Backend\App\Action\Context $context,
            \Vendor\Module\Model\EmployeeFactory $employeeFactory
        ) {
            parent::__construct($context);
            $this->employeeFactory = $employeeFactory;
        }
    
    
        public function execute()
        {
            $data = $this->getRequest()->getPostValue();
            if (!$data) {
    
                $this->_redirect('vendor_module/employee/edit'); // your edit url
                return;
            }
    
            try {
                $rawData = $this->employeeFactory->create();
                $rawData->setData($data);
                if (isset($data['entity_id'])) {
                    $rawData->setEntityId($data['entity_id']);
                }
                $rawData->save();
                $this->messageManager->addSuccess(__('Row data has been successfully saved.'));
            } catch (\Exception $e) {
                $this->messageManager->addError(__($e->getMessage()));
            }
            $this->_redirect('vendor_module/employee/index');
    
        }
    
    
    
    }

In Your ui component you have to declare the button:

<settings>
        <buttons>
            <button name="save" class="Vendor\Module\Block\Adminhtml\Employee\Edit\SaveButton"/>
        </buttons>
    </settings>

Please add controller file for save data in database

create save.php on below path

Vendor\Desconto\Controller\Adminhtml\Employee\save.php

<?php


namespace Vendor\Desconto\Controller\Adminhtml\Employee;

use Magento\Framework\Exception\LocalizedException;

class Save extends \Magento\Backend\App\Action
{

    private $dataPersistor;

    private $employeeModel;

    /**
     * @param \Magento\Backend\App\Action\Context $context
     * @param \Magento\Framework\App\Request\DataPersistorInterface $dataPersistor
     */
    public function __construct(
        \Magento\Backend\App\Action\Context $context,
        \Magento\Framework\App\Request\DataPersistorInterface $dataPersistor,
        \Vendor\Desconto\Model\Employee  $employeeModel
    ) {
        $this->dataPersistor = $dataPersistor;
        $this->employeeModel = $employeeModel;
        parent::__construct($context);
    }

    /**
     * Save action
     *
     * @return \Magento\Framework\Controller\ResultInterface
     */
    public function execute()
    {
        /** @var \Magento\Backend\Model\View\Result\Redirect $resultRedirect */
        $resultRedirect = $this->resultRedirectFactory->create();
        $data = $this->getRequest()->getPostValue();
        if ($data) {
            $id = $this->getRequest()->getParam('id_desconto');
        
            $model = $this->employeeModel->load($id);
            if (!$model->getId() && $id) {
                $this->messageManager->addErrorMessage(__('This item no longer exists.'));
                return $resultRedirect->setPath('*/*/');
            }
        
            $model->setData($data);
        
            try {
                $model->save();
                $this->messageManager->addSuccessMessage(__('You saved the data.'));
        
                if ($this->getRequest()->getParam('back')) {
                    return $resultRedirect->setPath('*/*/edit', ['id_desconto' => $model->getId()]);
                }
                return $resultRedirect->setPath('*/*/');
            } catch (LocalizedException $e) {
                $this->messageManager->addErrorMessage($e->getMessage());
            } catch (\Exception $e) {
                $this->messageManager->addExceptionMessage($e, __('Something went wrong while saving the data.'));
            }
        
            return $resultRedirect->setPath('*/*/edit', ['id_desconto' => $this->getRequest()->getParam('id_desconto')]);
        }
        return $resultRedirect->setPath('*/*/');
    }


}

hope this will help you :)
