Download the PHP package matatirosoln/doctrine-filemaker-driver without Composer

Doctrine FileMaker driver

A Doctrine driver to interact with FileMaker using the CWP API.

Installation

composer require matatirosoln/doctrine-filemaker-driver

Configuration

In your Doctrine configuration comment out

driver: xxxx

and replace it with

driver_class: MSDev\DoctrineFileMakerDriver\FMDriver

Conventions

1. Create a model to represent a FileMaker layout. Set the name of the layout as the model table.

   /**
    * Keyword
    *
    * @Table(name="Keyword")
    * @Entity(repositoryClass="Repository\KeywordRepository")
    */
    class Keyword

2. In your model create an id field which is mapped to the special rec_id pseudo field

   /**
    * @var int
    *
    * @Column(name="rec_id", type="integer")
    */
   private $id;

3. Create your 'actual' ID field, as used for relationships, as a separate property of your model. Set its GeneratedValue strategy to be Custom which will mean that Doctrie will wait for FM to assign that value - the assumption being that this is an auto-enter calc field (probaby Get(UUID)). You then need to specifiy the CustomIdGenerator and set this to MSDev\DoctrineFileMakerDriver\FMIdentityGenerator so that the value is returned as a string.

   /**

   • @var string
   • @Column(name="_pk_ClientID", type="string" length=255)
   • @Id
   • @GeneratedValue(strategy="CUSTOM")
   • @CustomIdGenerator(class="MSDev\DoctrineFileMakerDriver\FMIdentityGenerator") */ private $uuid;

   Alternatively you could generate the UUIDs in your model constructor (using for example ramsey/uuid). In this case you'd end up with something like

   /**
    * @var string
    *
    * @Column(name="__pk_CanvasID", type="string", length=255)
    * @Id
    */
    private $uuid;
   
    public function __construct()
    {
        $this->uuid = Uuid::uuid4()->toString();
    }

4. Add other properties as required. To access related fields on your layout enclose the field name in single quotes in the column mapping.

    /**
     * @var string
     *
     * @Column(name="'absCon::email'", type="string", length=255)
     */
    private $contactEmail;

5. If you need access to the record modification ID you can add the special mod_id pseudo property

   /**
    * @var int
    *
    * @Column(name="mod_id", type="integer")
    */
   private $modId;

6. To access query metadata add a rec_meta pseudo property of type json_array

   /**
   * @var array
   *
   * @Column(name="rec_meta", type="json_array")
   */
   private $meta;         

   This will be populated with an array containing

   [
        'found' => (int)$this->response->getFoundSetCount(),
        'fetch' => (int)$this->response->getFetchCount(),
        'total' => (int)$this->response->getTableRecordCount(),
   ]    

   Which you can then access from any record in your returned set.

Considerations

1. Because of the way in which more 'conventional' databases handle relationships, there is no concept of a portal. To access related data create a corresponding model for that table (layout) and create standard Doctrine relationships (OneToOne, OneToMany, ManyToOne etc).
2. If your model contains caclulation fields you will run into issues when trying to create a new record, since Doctrine will try and set those fields to null. One 'solution' to this is to create a 'stub' of your model which contains only the fields which are necesary to create a new record and to instantiate that for record creation. If you head down this route you'll likely want to create an interface which both your stub and your real entity implement so that you can typehint appropriately.

This driver has been developed for use within Symfony applications (because that's what we do). The Doctrine FileMaker bundle includes this driver as well as creating services to access scripts, containers, valuelists and more.
