How can I get the type of current user with PUGXMultiUserBundle ?
This code returns this error
{% if app.user.type == 'user_one' %}
//...
{% endif %}
This is the error
Method "type" for object "AppBundle\Entity\UserOne" does not exist
This is entity User
namespace AppBundle\Entity;
use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity
* #ORM\Table(name="user")
* #ORM\InheritanceType("JOINED")
* #ORM\DiscriminatorColumn(name="type", type="string")
* #ORM\DiscriminatorMap({"user_one" = "UserOne", "user_two" = "UserTwo"})
*
*/
abstract class User extends BaseUser
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
public function __construct()
{
parent::__construct();
// your own logic
}
}
after updating database there is a new field named type created in table user
Ah, I see the problem. In the twig file, you are calling:
{% if app.user.type == 'user_one' %}
Where "app.user" specifies the object, and "type" specifies the method. But you don't have a "method" defined in the Class. But instead you have the DiscriminatorColumn.
A method would be something like:
public function type(){
...
}
Hopefully that makes sense.

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:

I would like to reuse a select menu, but change every time the id and the name for it in Twig. How could it be done?
I thought of a wrapper block about the select menu and then extend it each time of reuse. But how to set the values for id and name using {{ parent() }}?
I do this by storing and creating the keys in my custom Twig_Extension class, here is a small setup for it. By keeping it global I can ensure unique id's in every view/macro/include ...
example.twig
{% for i in 1..5 %}
<ul id="{{ get_unique_key('my_menu') }}">
<li>Foo</li>
</ul>
{% endfor %}
ProjectTwigExtension
class ProjectTwigExtension extends Twig_Extension {
private $keys = array();
public function getFunctions() {
return array(
new Twig_SimpleFunction('get_unique_key', array($this, 'getUniqueKey')),
);
}
/**
* Create an unique HTML identifier
*
* #param $name String to make unique
*
* #returns String
*/
public function getUniqueKey($name) {
if (!in_array($name, $this->keys)) {
$this->keys[] = $name;
return $name;
}
$i = 0;
while(in_array($name.++$i,$this->keys)) {}
$this->keys[] = $name.$i;
return $name.$i;
}
public function getName() {
return 'ProjectTwigExtension';
}
}
Register extension
$twig = new Twig_Environment($loader);
$twig->addExtension(new ProjectTwigExtension());
I'm trying to get data for a new field added in login page. What I've done:
Modify AccountController.php login function adding new parameter: $this->_app->login($user, $client, !empty($data['rememberme']))
In Userfrosting.php login function i've set it in application: $this->client = $client;
In setupTwigUserVariables funtion added twig global: $twig->addGlobal("client", $this->client);
The problem is that in a template, {{client.id}} returns nothing. Any help will be appreciated.
In UserFrosting 4, you should create a Twig extension in your Sprinkle's src/Twig/ directory, and add the variable to the return value for getGlobals.
Your situation is a little tricky, since I'm not sure how client can be a global variable but at the same time depend on $data['client_id'] - which appears to be a request parameter. For now, I'll assume that you're submitting this parameter with any requests that require the client variable.
<?php
/**
* Stack Overflow
*
* #link https://stackoverflow.com
*/
namespace UserFrosting\Sprinkle\Site\Twig;
use Interop\Container\ContainerInterface;
use UserFrosting\Sprinkle\Site\Database\Models\Client;
/**
* Extends Twig functionality for the Site sprinkle.
*
* #author Jose Luis
*/
class Extension extends \Twig_Extension
{
protected $services;
protected $config;
public function __construct(ContainerInterface $services)
{
$this->services = $services;
$this->config = $services->config;
}
public function getName()
{
return 'myproject';
}
public function getGlobals()
{
try {
$currentUser = $this->services->currentUser;
// Assumes the client_id is being submitted as a query string (url) parameter
$clientId = $this->services->request->getQueryParam('client_id');
$client = Client::where('client_id', clientId)->where('userid', $currentUser->id)->first();
} catch (\Exception $e) {
$client = null;
}
return [
'client' => $client
];
}
}
You will then need to register this extension in your Sprinkle's service provider class:
<?php
/**
* Stack Overflow
*
* #link https://stackoverflow.com
*/
namespace UserFrosting\Sprinkle\Site\ServicesProvider;
use UserFrosting\Sprinkle\Site\Twig\Extension as JoseExtension;
/**
* Services provider for the Site sprinkle.
*
* #author Jose Luis
*/
class ServicesProvider
{
/**
* Register extended user fields services.
*
* #param Container $container A DI container implementing ArrayAccess and container-interop.
*/
public function register($container)
{
/**
* Extends the 'view' service with Jose's Twig Extension.
*/
$container->extend('view', function ($view, $c) {
$twig = $view->getEnvironment();
$extension = new JoseExtension($c);
$twig->addExtension($extension);
return $view;
});
}
}
Yes, I know that there is a lot of boilerplate here. However once you set these up the first time, it is easy to add new variables/functions/filters to the Twig environment and new services to your Sprinkle in the future.
How can I set the default value in field.
In my document I need to set default value false for field emailnotify
In mogodb th default value should be zero.
Check my document
namespace xxx\xxxBundle\Document;
use FOS\UserBundle\Document\User as BaseUser;
use Doctrine\ODM\MongoDB\Mapping\Annotations as MongoDB;
/**
* #MongoDB\Document
*/
class User extends BaseUser
{
/**
* #MongoDB\Id(strategy="auto")
*/
protected $id;
/**
* #MongoDB\Boolean
*/
protected $emailnotify;
/**
* Sets the emailnotify.
*
* #param boolean $emailnotify
*
* #return User
*/
public function setEmailnotify($emailnotify)
{
$this->emailnotify = (Boolean) $emailnotify;
return $this;
}
/**
* #return boolean
*/
public function isEmailnotify()
{
return $this->emailnotify;
}
}
I have found that setting the default value in the constructor works
public function __construct() {
$this->emailnotify = false;
}
Of course just setting the class variable to false will work for most parts if you use Doctrine to fetch the Document again afterwards, but the property will not be persisted to MongoDB like with the above.
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?
