The avrocsvbundle from dutchbridge

AvroCsvBundle

This bundle provides an easy way to upload data to your db using csv files with just a few configuration parameters.

Status

This bundle is under development and may break.

Limitations

This bundle uses php and Doctrine2 and is not your best bet for importing gargantuan csv files. Use your databases native importing & exporting solutions to skin that cat.

Features

Import data by csv file
Export data to csv file
A few services for reading/writing csv files

Supports

Doctrine ORM

Installation

This bundle is listed on packagist.

Simply add it to your apps composer.json file

    "avro/csv-bundle": "*"

Enable the bundle in the kernel as well as the dependent AvroCaseBundle:

// app/AppKernel.php
    new Avro\CsvBundle\AvroCsvBundle(),
    new Avro\CaseBundle\AvroCaseBundle()

Configuration

Add this required config to your app/config/config.yml file

avro_csv:
    db_driver: orm # supports orm
    batch_size: 15 # The batch size between flushing & clearing the doctrine object manager
    tmp_upload_dir: "%kernel.root_dir%/../web/uploads/tmp/" # The directory to upload the csv files to
    sample_count: 5 # The number of sample rows to show during mapping

Add routes to your app/config/routing.yml file

AvroCsvBundle:
    resource: "@AvroCsvBundle/Resources/config/routing.yml"

Add the entities/documents you want to implement importing/exporting for

avro_csv:
    # 
    objects: # the entities/documents you want to be able to import/export data with 
        client:
            class: Avro\CrmBundle\Entity\Client # The entity/document class
            redirect_route: avro_crm_client_list # The route to redirect to after import
        invoice:
            class: Avro\CrmBundle\Entity\Invoice
            redirect_route: avro_crm_invoice_list

To exclude certain fields from being mapped, use the ImportExclude annotation like so.

namespace Avro\CrmBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Avro\CsvBundle\Annotation\ImportExclude;

/**
 * Avro\CrmBundle\Entity\Client
 *
 * @ORM\Entity
 */
class Client
{
    /**
     * @var string
     *
     * @ORM\Column(type="string", length=100, nullable=true)
     * @ImportExclude
     */
    protected $password;

Importing

Implement importing for as many entities/documents as you like. All you have to do is add them to the objects node as mentioned previously.

Then just include a link to specific import page like so:

<a href="{{ path('avro_csv_import_upload', {'alias': 'client'}) }}">Go to import page</a>

Replace "client" with whatever alias you called your entity/document in the config.

Views

The bundle comes with some basic twitter bootstrap views that you can override by extending the bundle.

Customizing each row

Want to customize certain fields on each row? No problem.

An event is fired when a row is added that you can tap into to customize each row of data.

Just create a custom listener in your app that listens for the 'avro_csv.row_added' event.

For example...

<?php
namespace Avro\CrmBundle\Listener;

use Symfony\Component\Security\Core\SecurityContextInterface;

use Doctrine\ORM\EntityManager;
use Symfony\Component\EventDispatcher\Event;

/**
 * Csv import listener
 *
 * @author Joris de Wit <[email protected]>
 */
class ImportListener
{
    protected $em;
    protected $context;

    /**
     * @param EntityManager            $em      The entity manager
     * @param SecurityContextInterface $context The security context
     */
    public function __construct(EntityManager $em, SecurityContextInterface $context)
    {
        $this->em = $em;
        $this->context = $context;
    }

    /**
     * Set the objects createdBy field
     *
     * @param Event $event
     */
    public function setCreatedBy(Event $event)
    {
        $object = $event->getObject();

        $user = $this->context->getToken()->getUser();

        $object->setCreatedBy($user);
    }
}

services:
    import.listener:
        class: Avro\CrmBundle\Listener\ImportListener
        arguments: ["@doctrine.orm.entity_manager", "@security.context"]
        tags:
            - { name: kernel.event_listener, event: avro_csv.row_added, method: setCreatedBy }

Exporting

This bundle provides some simple exporting functionality.

Navigating to "/export/your-alias" will export all of your data to a csv and allow you to download it from the browser.

If you want to customize data returned, just create your own controller action and grab the queryBuilder from the exporter and add your constraints before calling "getContent()".

Ex.

    /**
     * Export a db table.
     *
     * @param string $alias The objects alias
     *
     * @return View
     */
    public function exportAction($alias)
    {
        $class = $this->container->getParameter(sprintf('avro_csv.objects.%s.class', $alias));

        $exporter = $this->container->get('avro_csv.exporter');
        $exporter->init($class);

        // customize the query
        $qb = $exporter->getQueryBuilder();
        $qb->where('o.fieldName =? 1')->setParameter(1, false);

        $content = $exporter->getContent();

        $response = new Response($content);
        $response->headers->set('Content-Type', 'application/csv');
        $response->headers->set('Content-Disposition', sprintf('attachment; filename="%s.csv"', $alias));

        return $response;
    }
