Talk on StripeCon EU 2018: An introductory talk about using SilverStripe without pages - as an application framework in comparison to Laravel or Django

2. /me
●
Web based business applications
●
Technology agnostic
●
PHP, Python, NodeJS, React,
●
Silverstripe, Laravel, Django
●
More consultant than developer

3. Criteria for frameworks
●
Results fast!
●
Incremental development
●
Simple but extensible structure
●
Stability: Static and dynamic

4. Framework Features
●
ORM
●
Admin Scaffolding
●
Integrated security
●
Form generation, scaffolding

6. Example: Everyday problems

8. Installation: Init
●
Prerequisites: PHP 7.2, composer
> mkdir monsters
> cd monsters
> composer init
Minimum Stability []: dev
Package Type []: project
License []: BSD-3-Clause
“prefer-stable”: true

9. Installation: Recipe
# Important to do now!
> mkdir public
# Base recipe
> composer require silverstripe/recipe-core
# Admin
> composer require silverstripe/admin
# File handling
> composer require silverstripe/asset-admin
...large output...

10. Installation: Confg fles

20. ModelAdmin
app/src/controllers/MonsterController.php
<?php
namespace AppAdmin;
use SilverStripeAdminModelAdmin;
use AppModelsMonster;
class MonsterAdmin extends ModelAdmin {
private static $url_segment = "monsters";
private static $menu_title = "Monsters";
private static $menu_priority = 1;
private static $managed_models = [
Monster::class
];
}

26. The Controller
app/src/controllers/MonsterController.php
<?php
namespace AppControllers;
use SilverStripeControlController;
class MonsterController extends Controller {
}

27. Routing
app/_confg/routes.yml
---
Name: approutes
After: framework/_config/routes#coreroutes
---
SilverStripeControlDirector:
rules:
'monsters//$Action/$ID': AppControllersMonsterController
'': AppControllersMonsterController

29. The View
app/src/controllers/
MonsterController.php
use SilverStripeControlController;
use AppModelsMonster;
class MonsterController extends Controller {
public function index($request)
{
return [
'Title' => 'Monsters',
'Objects' => Monster::get()
];
}
}
app/templates/App/Controllers/
MonsterController.ss
<h1 class="title">$Title</h1>
<% if $Monsters %>
<div class="columns">
<% loop $Monsters %>
<div class="column is-one-third">
<div class="box">
$Image.Fill(300, 200)
<p>$Name</p>
</div>
</div>
<% end_loop %>
</div>
<% end_if %>

41. Frontend editing!
●
German: DAU
●
Feel at home (branding)
●
Everyday tasks
●
Uncommon tasks
As simple as possible

42. Editing
app/src/controllers/MonsterController.php
class MonsterController extends Controller {
private static $allowed_actions = [
"edit",
"EditForm"
];
public function EditForm() {…}
public function edit(HTTPRequest $request) {}
public function save(array $data, Form $form) {}
}

43. Editing
app/src/controllers/MonsterController.php:EditForm()
$colors = Monster::singleton()->dbObject('Color')->enumValues();
$fields = FieldList::create(
TextField::create("Name", "Name"),
TextField::create("Eyes", "Number of eyes"),
DropdownField::create("Color", "Main color", $colors),
FileField::create("Image", "Image"),
HiddenField::create("ID", "ID")
);
$actions = FieldList::create(
FormAction::create('save','Save')->addExtraClass('is-primary')
);
$validator = RequiredFields::create('Name');

44. Editing
app/src/controllers/MonsterController.php
public function edit(HTTPRequest $request) {
$form = $this->EditForm();
$monster = null;
if($id = (int) $request->param("ID")) {
$monster = Monster::get()->byID($id);
$form->loadDataFrom($monster);
}
return [
'Monster' => $monster,
'Form' => $form
];
}

48. Editing
app/src/controllers/MonsterController.php
public function save(array $data, Form $form) {
if($id = $data["ID"]) {
$monster = Monster::get()->byID($id);
} else {
$monster = Monster::create();
}
$form->saveInto($monster);
$monster->write();
$this->redirect($this->Link("view/$monster->ID"));
}

50. SilverStripe as Framework
●
Batteries included
– Versioning, Translations, Extensions, REST
●
Admin
●
Very fast development cycle (dev/build)
●
Confguration not always transparent
●
SilverStripe 4 was a big step
