i overrided the twig error pages and i've got an extension to get some settings for layout but i can't access this extension in the error pages
Here is my extension
/**
* Class ThemeExtension.
*/
class ThemeExtension extends AbstractExtension
{
use SettingManagerTrait;
/**
* #var TokenStorageInterface
*/
private $tokenStorage;
/**
* #var AuthorizationCheckerInterface
*/
private $authorizationChecker;
/**
* #var RequestStack
*/
private $stack;
/**
* #var array
*/
private $available_colors;
/**
* ThemeExtension constructor.
*
* #param TokenStorageInterface $tokenStorage
* #param AuthorizationCheckerInterface $authorizationChecker
* #param RequestStack $stack
* #param array $available_colors
*/
public function __construct(TokenStorageInterface $tokenStorage, AuthorizationCheckerInterface $authorizationChecker, RequestStack $stack, array $available_colors)
{
$this->tokenStorage = $tokenStorage;
$this->authorizationChecker = $authorizationChecker;
$this->stack = $stack;
$this->available_colors = $available_colors;
}
/**
* #return array
*/
public function getFunctions(): array
{
return [
new TwigFunction('theme_name', [$this, 'getThemeName']),
];
}
/**
* #return string
*
* #throws NonUniqueResultException
*/
public function getThemeName(): string
{
// stuff
}
}
I would like to know how to use this in error pages if somebody knows. Thank you for any help or idea. Maybe it's not possible
I have under_score named properties in my class like transaction_id or web_order_item_id. And I want to customize the parameter name in my setters when I generate it.
For now it generate this:
/**
* #param int $original_transaction_id .camelCase()
*/
public function setOriginalTransactionId(int $original_transaction_id): void
{
$this->original_transaction_id = $original_transaction_id;
}
But I want this:
/**
* #param int $originalTransactionId .camelCase()
*/
public function setOriginalTransactionId(int $originalTransactionId): void
{
$this->original_transaction_id = $originalTransactionId;
}
I have tried to change this behavior in Settings/Editor/File and Code Templates/Code/Php Setter Method but I couldn`t found ability to do it.
There is a variable in the template:
${NAME}
But it returned value in this form $OriginalTransactionId instead $originalTransactionId
You can try using Apache Velocity StringUtils here, like
#set($Setter_param = ${StringUtils.removeAndHump(${PARAM_NAME})})
#set($Setter_param = $Setter_param.substring(0,1).toLowerCase() + $Setter_param.substring(1))
/**
* #param ${TYPE_HINT} $${Setter_param}
*/
public ${STATIC} function set${NAME}(#if (${SCALAR_TYPE_HINT})${SCALAR_TYPE_HINT} #end$${Setter_param})#if (${VOID_RETURN_TYPE}):void #end
{
#if (${STATIC} == "static")
self::$${FIELD_NAME} = $${Setter_param};
#else
$this->${FIELD_NAME} = $${Setter_param};
#end
}
I have a controller method which I am using to "collect" variables to be assigned to template. I have overridden controller's render() method to merge "collected" and render parameters and assign them to template.
Example:
class Controller extends \Symfony\Bundle\FrameworkBundle\Controller\Controller
{
private $jsVars = [];
protected function addJsVar($name, $value)
{
$this->jsVars[$name] = $value;
}
public function render($view, array $parameters = [], Response $response = null)
{
return parent::render($view, array_merge($parameters, ['jsVars' => $this->jsVars], $response);
}
public function indexAction()
{
// collect variables for template
$this->addJsVar('foo', 'bar');
return $this->render('#App/index.html.twig', ['foo2' => 'bar2']);
}
}
I just upgraded to Symfony 3.4 which complains that since Symfony4 I am not allowed to override render() method as it will be final.
How could I make it work seamlessly, i.e without defining a new method?
I know about Twig globals but these dont help me
I could use a service to collection variables and inject that service to Twig but that seems odd
Are there events I could listen, e.g TwigPreRender or smth?
You can render a controller from inside Twig like that:
{{ render(controller('App\\Controller\\YourController::yourAction', { 'args': 'hi' })) }}
Documentation here
Seems that there is no easy way.
Basically there are 2 options:
create your own template engine by extending current Symfony\Bundle\TwigBundle\TwigEngine
decorate current templating engine service templating.engine.mytwig
I chose the latter.
Few explanations:
I created service templating.engine.mytwig which decorates current engine templating.engine.twig. Class will get current ´TwigEngine` as input and I'll delegate most of the stuff to it
The class also needs to be twig extension by implementing \Twig_ExtensionInterface (or extending \Twig_Extension was sufficient for me). Also service needs to have tag twig.extension. Otherwise you'll end up having errors such as "Cannot find private service 'assetic' etc"
setParameter/getParameter are for collecting and returning parameters
Then I added shortcut methods to my Controller - setJsVar
Twig template requires also handling of those variables, preferably somewhere in the layout level. But that is not included here
One could you this solution to collect arbitrary template parameters, e.g if you want to assign from another method or whatever
It would be good idea to clear collected parameters after render
Was that all worth it? I dont know :) Cannot understand why Symfony team chose to make Controller::render final in the first place. But anyway here it is:
TwigEnging class:
namespace My\CommonBundle\Component\Templating\MyTwigEngine;
use Symfony\Bundle\FrameworkBundle\Templating\EngineInterface;
use Symfony\Bundle\TwigBundle\TwigEngine;
use Symfony\Component\HttpFoundation\Response;

A lot of times in a Zend Framework 2 view I'll be calling $this->escapeHtml() to make sure my data is safe. Is there a way to switch this behaviour from a blacklist to a whitelist?
PS: Read an article from Padraic Brady that suggests that automatic escaping is a bad idea. Additional thoughts?
You could write your own ViewModel class which escapes data when variables are assigned to it.
Thanks to Robs comment, I extended the ZF2 ViewModel as follows:
namespace Application\View\Model;
use Zend\View\Model\ViewModel;
use Zend\View\Helper\EscapeHtml;
class EscapeViewModel extends ViewModel
{
/**
* #var Zend\View\Helper\EscapeHtml
*/
protected $escaper = null;
/**
* Proxy to set auto-escape option
*
* #param bool $autoEscape
* #return ViewModel
*/
public function autoEscape($autoEscape = true)
{
$this->options['auto_escape'] = (bool) $autoEscape;
return $this;
}
/**
* Property overloading: get variable value;
* auto-escape if auto-escape option is set
*
* #param string $name
* #return mixed
*/
public function __get($name)
{
if (!$this->__isset($name)) {
return;
}
$variables = $this->getVariables();
if($this->getOption('auto_escape'))
return $this->getEscaper()->escape($variables[$name]);
return $variables[$name];
}
/**
* Get instance of Escaper
*
* #return Zend\View\Helper\EscapeHtml
*/
public function getEscaper()
{
if (null === $this->escaper) {
$this->escaper = new EscapeHtml;
}
return $this->escaper;
}
}
In a Controller it could be used like this:
public function fooAction()
{
return new EscapeViewModel(array(
'foo' => '<i>bar</i>'
));
//Turn off auto-escaping:
return new EscapeViewModel(array(
'foo' => '<i>bar</i>'
),['auto_escape' => false]);
}
Question:
I would appreciate it if soemebody would comment, if this is best practice or if there is a better and ecp. more efficient and resource-saving way?
I have tried to generate java classes from a schema xsd with JAXB2.1 and run XJC and it works.
I have included the schema in a wsdl file and i generate java classes with wsdl2java command using CXF.
The problem is abouta java class where there are difference:
The difference is the content attribute and its getter and setter which is missing with wsdl2java command.

I need this attribute into this class.
Is there a way to do this like add a parameter?
This is my wsdl2java command:
call wsdl2java -Debug -verbose -exsh true -autoNameResolution -p %PACKAGE_BASE%.pa -p "urn:hl7-org:v3"=%PACKAGE_BASE%.patient.hl -d %PROJECT_HOME%\src\main\java\ %WSDL_HOME%\Test.wsdl
