Domain-Driven Design

Domain
activity or business of the user

is about

• focussing on the domain and domain logic

• accurately mapping the concepts to software

• forming a ubiquitous language among the
project members

Hanau, Germany


Ubiquitous Language
• important prerequisite for successful
collaboration

• use the same words for

• discussion

• modeling

• development

Object Management

Dependency Injection
• a class doesn't create or retrieve the instance
of another class but get's it injected

• fosters loosely-coupling and high cohesion

‣ more stable, reusable code

Hanau, Germany

Object Management

FLOW3's take on Dependency Injection
• one of the ﬁrst PHP implementations
(started in 2006, improved ever since)

• object management for the whole lifecycle of all objects

• no unnecessary conﬁguration if information can be
gatered automatically (autowiring)

• intuitive use and no bad magical surprises

• fast! (like hardcoded or faster)

Your Own Commands

$ ./flow3 kickstart:commandcontroller Acme.Demo Test

Hanau, Germany

Validation

Validation is about different things

• incoming data needs to be validated for security reasons

• no evil markup in submitted content

• domain model integrity needs to be ensured

• an email needs to be (syntactically) valid

• credit card numbers should consist only of digits

Hanau, Germany

Validation

Validation in FLOW3

• you do not want to code checks into your controllers

• FLOW3 separates validation from your controller’s concerns

• no PHP code needed for validation

• declared through annotations

Hanau, Germany

Validation

Validation Models

• BaseProperties
rules defining the minimum requirements on individual properties of a
model

• BaseModel
rules or custom validators enforcing the minimum requirements on the
combination of properties of a model

• Supplemental
rules defining additional requirements on a model for a specific
situation (e.g. a certain action method)

Hanau, Germany

Validation

Base Properties

• Validation rules deﬁned directly at the properties

/**
* @var string
* @validate StringLength(minimum = 10, maximum = 100)
*/
protected $title;

/**
* @var string
* @validate StringLength(minimum = 1, maximum = 50)
*/
protected $author;

Hanau, Germany

Validation

Validators

• validators provided by FLOW3 can be used through their short name

• Count, Float, NotEmpty, RegularExpression, Uuid, DateTime,
NumberRange, StringLength, Alphanumeric, Integer, Number, String,
EmailAddress, Label, Raw, Text

• custom validators need to implement the ValidatorInterface

• use them by specifying the fully qualiﬁed class name
/**
* @var DambekalnsStuffDomainModelStuff
* @validate DambekalnsStuffDomainValidatorStuffValidator
*/
protected $stuff;

Hanau, Germany

Property Mapper

Transfer properties from A to B
• Allows for complete or partial copying of objects and object
graphs

• Is used by the MVC framework for the mapping of raw GET and
POST data to Argument objects

Hanau, Germany

Property Mapper

$articleArray = array(
'headline' => 'Hello World!',
'story' => 'Just a demo ...'
);

$article = $mapper->convert($sourceArray, 'Acme.DemoDomainModelArticle');

Hanau, Germany

Resource Management

Image Upload
Resources are handled like other properties in a form:

<f:form method="blog" action="update" object="{blog}" name="blog"
enctype="multipart/form-data">
<f:if condition="{blog.authorPicture}">
<img src="{f:uri.resource(resource: blog.authorPicture)}" />
</f:if>
<label for="authorPicture">Author picture</label>
<f:form.upload property="authorPicture" id="authorPicture" />
<f:form.submit value="Update"/>
</f:form>

Hanau, Germany

Property Mapper

Allow nested object structures
For security reasons the creation of nested structure through the
property mapper is disabled by default

/**
* @return void
*/
public function initializeUpdateAction() {
$this->arguments['article']->getPropertyMappingConfiguration()
->allowCreationForSubProperty('picture');
$this->arguments['article']->getPropertyMappingConfiguration()
->allowModificationForSubProperty('picture');
}

Hanau, Germany

Persistence

Object Persistence in the Flow
• based on Doctrine 2

• seamless integration into FLOW3

• provides all the great Doctrine 2 features

• uses UUIDs

• low level persistence API

• allows for own, custom persistence
backends (instead of Doctrine 2)

• e.g. CouchDB, Solr

Hanau, Germany

Basic Object Persistence

// Create a new customer and persist it:
$customer = new Customer("Robert");
$this->customerRepository->add($customer);

// Find an existing customer:
$otherCustomer = $this->customerRepository->findByFirstName("Karsten");

// and delete it:
$this->customerRepository->remove($otherCustomer);

Hanau, Germany

Validation and Doctrine Annotations

namespace TYPO3BlogDomainModel;

/**
* A Blog object
*
* @Entity
*/
class Blog {

/**
* @var string
* @validate Text, StringLength(minimum = 1, maximum = 80)
* @Column(length="80")
*/
protected $title;

/**
* @var DoctrineCommonCollectionsCollection<TYPO3BlogDomainModelPost>
* @OneToMany(mappedBy="blog")
* @OrderBy({"date" = "DESC"})
*/
protected $posts;

...

}

Hanau, Germany

Persistence-related Annotations

@Entity Declares a class as "entity"

@Column Controls the database column related to the class
property. Very useful for longer text content
(type="text" !)

@ManyToOne Deﬁnes relations to other entities. Unlike with
@OneToMany vanilla Doctrine targetEntity does not have to be
@ManyToMany given but will be reused from the @var
@OneToOne annotation.

cascade can be used to cascade operation to
related objects.

Hanau, Germany

Persistence-related Annotations

@var Deﬁnes the type of a property, collections can be
typed using angle brackets:
DoctrineCommonCollectionsCollection<TYPO3ConferenceDomainModelComment>

@transient The property will be ignored, it will neither be
persisted nor reconstituted

@identity Marks the property as part of an objects identity

Hanau, Germany

Custom Queries using the Query Object Model
/**
* A PostRepository
*/
class PostRepository extends TYPO3FLOW3PersistenceRepository {

/**
* Finds posts by the specified tag and blog
*
* @param TYPO3BlogDomainModelTag $tag
* @param TYPO3BlogDomainModelBlog $blog The blog the post must refer to
* @return TYPO3FLOW3PersistenceQueryResultInterface The posts
*/
public function findByTagAndBlog(TYPO3BlogDomainModelTag $tag,
TYPO3BlogDomainModelBlog $blog) {
$query = $this->createQuery();
return $query->matching(
$query->logicalAnd(
$query->equals('blog', $blog),
$query->contains('tags', $tag)
)
)
->setOrderings(array(
'date' => TYPO3FLOW3PersistenceQueryInterface::ORDER_DESCENDING)
)
->execute();
}
}

Hanau, Germany

Schema Management

Doctrine 2 Migrations
• Migrations allow schema versioning and
change deployment

• Migrations are the recommended way for
DB updates

• Tools to create and deploy migrations are
integrated with FLOW3

Hanau, Germany

Schema Management

Running Migrations
• needed after installation or upgrade:

$ ./flow3 doctrine:migrate

Hanau, Germany

Schema Management

Manual database updates
• for simple situations this can be good enough:

$ ./flow3 doctrine:create

$ ./flow3 doctrine:update

• useful when

• you are just starting a project and have never released

Hanau, Germany

Schema Management

Generating migrations

$ ./flow3 doctrine:migrationgenerate
Generated new migration class to "…/Version20110608074324.php"
from schema differences.
$

• Generated migrations can contain errors and should be checked
and adjusted as needed

• Migrations need to be moved to their “owning” package manually

Fluid

Example for assigning a string to a Fluid variable:

// in the action controller:
$this->view->assign('title', 'Welcome to Fluid');


<head>
<title>{title}</title>
</head>

Hanau, Germany

Fluid

Variables can also be objects:

$this->view->assign('conference', $conference);

<div class="venue">
<p>Venue Street: {conference.venue.street}</p>
</div>

Hanau, Germany

Fluid

if-then-else:

$this->view->assign('post', $blogPost);

<f:if condition="{post.comments}">
<f:then>There are some comments.</f:then>
<f:else>There are no comments.</f:else>
</f:if>

Hanau, Germany

Fluid

for-each:

$this->view->assign('ages', array("Karsten" => 34, "Robert" => 35));

<ul>
<f:for each="{ages}" as="age" key="name">
<li>{name} is {age} year old.</li>
</f:for>
</ul>

Hanau, Germany

Fluid

for-each:

$this->view->assign('post', $blogPost);

<f:if condition="{post.comments}">
<ul>
<f:for each="{post.comments}" as="comment" >
<li>{post.title}</li>
</f:for>
</ul>
</f:if>

Security

Touchless Security, Flow-Style
• security is handled at a central place (through AOP)

• third-party code is as secure as possible by default

• modeled after our experiences in the TYPO3 project and
Spring Security (Java framework)

• provides authentication, authorization, validation, ﬁltering ...

• can intercept arbitrary method calls

• transparently ﬁlters content through query-rewriting

• extensible for new authentication or authorization mechanisms

AOP

Aspect-Oriented Programming
• programming paradigm

• separates concerns to improve modularization

• OOP modularizes concerns into objects

• AOP modularizes cross-cutting concerns into aspects

• FLOW3 makes it easy (and possible at all) to use AOP in PHP

Signal-Slot Event Handling

Signal

• can be ﬁred on any event

• can be freely deﬁned by the developer

Slot

• is invoked when a signal is emitted

• any method can be used as a slot

any signal can be wired to any slot

Hanau, Germany


/**
* @param F3BlogDomainModelPost $post
* @param F3BlogDomainModelComment $newComment
* @return void
*/
public function createAction(F3BlogDomainModelPost $post,
F3BlogDomainModelComment $newComment) {
$post->addComment($newComment);
$this->emitCommentCreated($newComment, $post);
…
}

/**
* @param F3BlogDomainModelComment $comment
* @return void
* @signal
*/
protected function emitCommentCreated(F3BlogDomainModelComment $comment,
F3BlogDomainModelPost $post) {}

Hanau, Germany


Signals are wired to Slots in a package’s bootstrap:

/**
* Invokes custom PHP code directly after the package manager has been
* initialized.
*
* @param F3FLOW3CoreBootstrap $bootstrap The current bootstrap
* @return void
*/
public function boot(F3FLOW3CoreBootstrap $bootstrap) {
$dispatcher = $bootstrap->getSignalSlotDispatcher();
$dispatcher->connect(
'F3BlogControllerCommentController', 'commentCreated',
'F3BlogServiceNotification', 'sendNewCommentNotification'
);
}

Hanau, Germany


Any method can be a slot:

/**
* @param F3BlogDomainModelComment $comment
* @return void
*/
public function sendNewCommentNotification(F3BlogDomainModelComment $comment,
F3BlogDomainModelPost $post) {

$mail = new F3SwiftMailerMessage();
$mail
->setFrom(array('john@doe.org ' => 'John Doe'))
->setTo(array('karsten@typo3.org ' => 'Karsten Dambekalns'))
->setSubject('New comment on blog post "' . $post->getTitle() . '"')
->setBody($comment->getContent())
->send();
}
