How to pass id from ui_component to model?

Question

I have a form, see image below.

I have the following data in the database, see image below

I originally wanted to have the structure like below in the custom table

> id | meta_key   |  meta_value
> ------------------------------- 
> 1  | first_name |  Absolute
> ------------------------------
> 2  | last_name  |  Idiot

But I don't know how to do this with ui_component (update, retrieve data)? (if someone knows how to do this. please provide some info)

So I resorted to what I know of

My current problem, when I load the form, I don't want to pass id/1 in my URL instead, I want the data from id 1 to be loaded by default.

Assuming the only needed codes are ui_component_form and data provider I have provided them below.

DataProvider.php

<?php
namespace Absolute\Idiot\Model\Sample1;
use Absolute\Idiot\Model\ResourceModel\Sample1\CollectionFactory;
class DataProvider extends \Magento\Ui\DataProvider\AbstractDataProvider
{
    public function __construct(
        $name,
        $primaryFieldName,
        $requestFieldName,
        CollectionFactory $contactCollectionFactory,
        array $meta = [],
        array $data = []
    ) {
        $this->collection = $contactCollectionFactory->create();
        parent::__construct($name, $primaryFieldName, $requestFieldName, $meta, $data);
    }

    public function getData()
    {
        if (isset($this->loadedData)) {
            return $this->loadedData;
        }

        $items = $this->collection->getItems();
        $this->loadedData = array();
        foreach ($items as $user) {
            $this->loadedData[$user->getId()]['sample1'] = $user->getData();
        }

        return $this->loadedData;

    }
}

Answer 1

In your listing.xml uicompnent file set actionsColumn node to set URL of edit and delete.

here my view/adminhtml/ui_component/sample_listing.xml

<actionsColumn name="actions" class="Vendor\Module\Ui\Component\Listing\Column\PR\Actions">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="resizeEnabled" xsi:type="boolean">true</item>
                    <item name="resizeDefaultWidth" xsi:type="string">107</item>
                    <item name="indexField" xsi:type="string">id</item>
                    <item name="sortOrder" xsi:type="number">7</item>
                </item>
            </argument>
        </actionsColumn>

set correct class and ID in this file class="Vendor\Module\Ui\Component\Listing\Column\PR\Actions" and indexField ID

Vendor\Module\Ui\Component\Listing\Column\PR\Actions

    }

    public function prepareDataSource(array $dataSource)
    {

                if (isset($item['id'])) {
                    $item[$name]['edit'] = [
                        'href' => $this->urlBuilder->getUrl($this->editUrl, ['id' => $item['id']]),
                        'label' => __('Edit')

                            'title' => __('Delete ${ $.$data.title }'),
                            'message' => __('Are you sure you wan\'t to delete a ${ $.$data.title } record?')
                        ]
                    ];

            }
