# Write implementation

{% hint style="success" %}
This is the official documentation of the `forestadmin/laravel-forestadmin` v2+ and `forestadmin/symfony-forestadmin` PHP agents.
{% endhint %}

Making your records editable is achieved by implementing the `create`, `update` and `delete` methods.

The 3 methods take a [filter](/developer-guide-agents-php/data-sources/getting-started/queries/filters.md) as a parameter but note that, unlike the `list` method, there is no need to support paging.

```php
<?php

use ForestAdmin\AgentPHP\DatasourceToolkit\Collection;
use ForestAdmin\AgentPHP\DatasourceToolkit\Components\Caller;
use ForestAdmin\AgentPHP\DatasourceToolkit\Components\Contracts\DatasourceContract;
use ForestAdmin\AgentPHP\DatasourceToolkit\Components\Query\Filters\Filter;
use ForestAdmin\AgentPHP\DatasourceToolkit\Components\Query\Projection\Projection;
use ForestAdmin\AgentPHP\DatasourceToolkit\Schema\ColumnSchema;
use GuzzleHttp\Client;

class MyCollection extends Collection
{
    public function __construct(DatasourceContract $datasource)
    {
        parent::__construct(
            $datasource,
            'MyCollection'
        );

        $this->addField('id', new ColumnSchema(
            // ...
            isReadOnly: true,
        ));

        $this->addField('title', new ColumnSchema(
            // ...
            isReadOnly: false,
        ));

        $this->client = new Client([
            'base_uri' => 'https://my-api/',
            'timeout'  => 5.0,
        ]);
    }

    public function create(Caller $caller, array $records)
    {
        $results = [];

        foreach ($records as $record) {
            try {
                $response = $this->httpClient->post(
                    'my-collection',
                    ['json' => $record]
                );

                $results[] = json_decode($response->getBody()->getContents(), true);
            } catch (\Exception $e) {
                throw new \Exception("Error creating record: " . $e->getMessage(), 0, $e);
            }
        }

        return $results;
    }

    public function update(Caller $caller, Filter $filter, array $patch)
    {
        $recordIds = $this->list($caller, $filter, new Projection('id'));

        foreach ($recordIds as $record) {
            try {
                $this->client->patch("my-collection/{$record['id']}", [
                    'json' => $patch,
                ]);
            } catch (\Exception $e) {
                throw new \Exception("Error updating record {$record['id']}: " . $e->getMessage());
            }
        }

    }

    public function delete(Caller $caller, Filter $filter): void
    {
        $recordIds = $this->list($caller, $filter, new Projection('id'));

        foreach ($recordIds as $record) {
            try {
                $this->client->delete("my-collection/{$record['id']}");
            } catch (\Exception $e) {
                throw new \Exception("Error updating record {$record['id']}: " . $e->getMessage());
            }
        }
    }
}
