Tackling the Heart of Software Development

Domain-Driven DesignA methodology which ...

• results in rich domain models

• provides a common language across the project team

• simplify the design of complex applications

Domain-Driven Design

Domain activity or business of the user

Domain-Driven Design 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

• documentation

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)

• new operator is supported

• proxy classes are created on the fly

• in production context all code is static

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

• BasePropertiesrules defining the minimum requirements on individual properties of a model

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

• Supplementalrules 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 \Dambekalns\Stuff\Domain\Model\Stuff * @validate \Dambekalns\Stuff\Domain\Validator\StuffValidator */ 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.Demo\Domain\Model\Article');

Hanau, Germany

Resource Management

<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>

Image Upload

Resources are handled like other properties in a form:

Hanau, Germany

Property Mapper

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

->allowCreationForSubProperty('picture'); $this->arguments['article']->getPropertyMappingConfiguration()

->allowModificationForSubProperty('picture'); }

Allow nested object structures

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

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 TYPO3\Blog\Domain\Model;

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

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

/** * @var \Doctrine\Common\Collections\Collection<\TYPO3\Blog\Domain\Model\Post> * @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 @OneToMany @ManyToMany@OneToOne

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

cascade can be used to cascade operation to related objects.

Hanau, Germany

@var Defines the type of a property, collections can be typed using angle brackets:\Doctrine\Common\Collections\Collection<\TYPO3\Conference\Domain\Model\Comment>

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

@identity Marks the property as part of an objects identity

Persistence-related Annotations

Hanau, Germany

Custom Queries using the Query Object Model

/** * A PostRepository */class PostRepository extends \TYPO3\FLOW3\Persistence\Repository {

/** * Finds posts by the specified tag and blog * * @param \TYPO3\Blog\Domain\Model\Tag $tag * @param \TYPO3\Blog\Domain\Model\Blog $blog The blog the post must refer to * @return \TYPO3\FLOW3\Persistence\QueryResultInterface The posts */ public function findByTagAndBlog(\TYPO3\Blog\Domain\Model\Tag $tag, \TYPO3\Blog\Domain\Model\Blog $blog) { $query = $this->createQuery(); return $query->matching( $query->logicalAnd( $query->equals('blog', $blog), $query->contains('tags', $tag) ) ) ->setOrderings(array( 'date' => \TYPO3\FLOW3\Persistence\QueryInterface::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

$ ./flow3 doctrine:create

$ ./flow3 doctrine:update

Manual database updates

• for simple situations this can be good enough:

• useful when

• you are just starting a project and have never released

Hanau, Germany

Schema Management

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

Generating migrations

• 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:

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

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

Hanau, Germany

Fluid

Variables can also be objects:

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

// in the action controller: $this->view->assign('conference', $conference);

Hanau, Germany

Fluid

if-then-else:

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

// in the action controller: $this->view->assign('post', $blogPost);

Hanau, Germany

Fluid

for-each:

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

// in the action controller: $this->view->assign('ages', array("Karsten" => 34, "Robert" => 35));

Hanau, Germany

Fluid

for-each:

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

// in the action controller: $this->view->assign('post', $blogPost);

Hanau, Germany

Fluid

View helpers – in this case the link.action view helper:

 {namespace f=F3\Fluid\ViewHelpers}

<f:link.action action="delete" arguments="{post: post, really: 'yes'}"> Delete this post </f:link.action>

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

Hanau, Germany

AOP

FLOW3 uses AOP for ...

• persistence magic

• logging

• debugging

• security

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 \F3\Blog\Domain\Model\Post $post * @param \F3\Blog\Domain\Model\Comment $newComment * @return void */ public function createAction(\F3\Blog\Domain\Model\Post $post, \F3\Blog\Domain\Model\Comment $newComment) { $post->addComment($newComment); $this->emitCommentCreated($newComment, $post); … }

/** * @param \F3\Blog\Domain\Model\Comment $comment * @param \F3\Blog\Domain\Model\Post $post * @return void * @signal */ protected function emitCommentCreated(\F3\Blog\Domain\Model\Comment $comment, \F3\Blog\Domain\Model\Post $post) {}

Hanau, Germany


/** * Invokes custom PHP code directly after the package manager has been * initialized. * * @param \F3\FLOW3\Core\Bootstrap $bootstrap The current bootstrap * @return void */ public function boot(\F3\FLOW3\Core\Bootstrap $bootstrap) { $dispatcher = $bootstrap->getSignalSlotDispatcher(); $dispatcher->connect( 'F3\Blog\Controller\CommentController', 'commentCreated', 'F3\Blog\Service\Notification', 'sendNewCommentNotification' ); }

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