Choosing custom template file in Symfony controller - symfony

I'm relatively new to Symfony, and currently using v 2.8. I've been using the #Template annotation successfully like this:
/**
* #Route("/editleague/")
* #Template()
*/
public function editAction() {
return $array;
}
And that successfully renders the twig template at Bundle/Resources/views/Default/edit.html.twig
I decided I want a different response (not a Twig template) if it was a post request, so just to start off, I changed the above code to:
/**
* #Route("/editleague/")
*/
public function editAction() {
return $this->render("Default/edit.html.twig",$array);
}
But I get a 500 error. I've tried various combinations, but haven't gotten anything to work where I can control the rendered template in the function itself. I believe it's a simple issue that someone with more experience will be able to figure out in seconds.

Since your template is in your bundle's Resources directory, you should use the Symfony logical name in your call to render:
'AppBundle:Default:edit.html.twig'
or:
':Default:edit.html.twig'
See the difference between paths to templates stored in a bundle versus templates in your app directory.

Change Browser language or project language to test localisation

this is my first time of developing with translation service.
I implemented it, seems to be working, but how can I test other languages?
Can I change the default language in my symfony project?
Or can I change the language transfered to my project via the browser?
(I only found the settings to change browser GUI language)
Regards
n00n
you can also do it inside controller using the session like this:
/**
* Switch language
*
* #Route("/switchLanguage/{locale}/", name="switch_language")
*
* #param Request $request
* #param string $locale
*
* #return RedirectResponse
*/
public function switchLanguageAction(Request $request, $locale): RedirectResponse
{
$request->attributes->set('_locale', null);
$this->get('session')->set('_locale', $locale);
return $this->redirect($request->headers->get('referer'));
}
Yes of course you can there is few approach for translation.
If you want save your project translation data in your database you must create entities for data translation and after that you can use global sql filter for selecting data each language.
And you can read about Symfony Translation Component.
For changing project language you can write listener.
like this
public function onKernelRequest(GetResponseEvent $event)
{
/** Set language parameter*/
$lang = $event->getRequest()->query->get('lang', 'en'); //this is optional you can write another code for getting language.
$event->getRequest()->setLocale($lang);
}
This example if you want to set each request language.
Read symfony translation component documentation there are more useful things.

defines manually routes using Symfony2

I've set up my entities, now I want to
use the doctrine:generate:crud, during this command it asks what route
prefix I would like. I would expect that this means that the routes
would automatically be generate, this is not happening. So I need to
know if it is supposed to generate the routes, or if I'm supposed to
create them all manually? If it is the case that I need to generate
them manually is there a route class, to define all the routes for the
CRUD operations?
When you generate a CRUD with Symfony, it will ask you to choose a configuration format.
By default, it's annotation. If you haven't changed it, then your routes are in the entity controller, as annotation.
In the example below, you can see the #Route anotation, which is how to define the URL in anotation.
/**
* Finds and displays a user entity.
*
* #Route("/user/{id}", name="user_show")
* #Method("GET")
*
* #param User $user
* #return \Symfony\Component\HttpFoundation\Response
*/
public function showAction(User $user) {
$deleteForm=$this->createDeleteForm($user);
return $this->render('security/show.html.twig', array(
'security'=>$user,
'delete_form'=>$deleteForm->createView(),
));
}
In the end, it's not that "It didn't happen", it's simply and most likely that you haven't read some doc, and didn't knew about it... ;)
Symfony doc: Routing

Symfony: Where do I put the code to register a custom MimeTypeGuesser?

I need to register a custom MimeTypeGuesser so I can add in some logic to handle .docx files, which my web server's installation of PHP is treating as application/zip (which is technically correct). I want it recognized as application/msword or application/vnd.openxmlformats-officedocument.wordprocessingml.document.
In the filedoc comment for the class Symfony\Component\HttpFoundation\File\MimeType, there's some info on how to register a custom guesser:
* You can register custom guessers by calling the register() method on the
* singleton instance. Custom guessers are always called before any default ones.
*
* $guesser = MimeTypeGuesser::getInstance();
* $guesser->register(new MyCustomMimeTypeGuesser());
Great, but where is an appropriate place for this registration code?
I'd want this to be an app-wide change, but I can't think of a good place to put it.
To be honest, I myself can't say for sure which place would be appropriate to register custom guesser, so I will simply suggest you one.
Since you're aiming for a app-wide solution, I believe overriding the build method of your Bundle class would do the trick.
Let's assume your bundle is named AppBundle, then your Bundle configuration file should be AppBundle.php located in src/AppBundle/AppBundle.php
Normally that file should be nothing, but an empty class that extends Symfony's core Bundle class - Symfony\Component\HttpKernel\Bundle\Bundle.
From there you can override the build method that we inherit from Bundle\Bundle and register your guesser. Normally build() is used to register custom extension, such as payment gateways, or compiler passes and stuff like that. You can see that left in comments actually:
/**
* Builds the bundle.
*
* It is only ever called once when the cache is empty.
*
* This method can be overridden to register compilation passes,
* other extensions, ...
*
* #param ContainerBuilder $container A ContainerBuilder instance
*/
public function build(ContainerBuilder $container)
{
}
So, add the following statements at the top of your class:
use Symfony\Component\HttpFoundation\File\MimeType\MimeTypeGuesser;
use Symfony\Component\DependencyInjection\ContainerBuilder;
And then simply override the method:
public function build(ContainerBuilder $container) {
parent::build($container);
$guesser = MimeTypeGuesser::getInstance();
$guesser->register( new MyMimeTypeGuesser() );
}
This would load your custom guesser once the application loads all of its bundles. I would like to say that this might not be the perfect solution, but for the time being it can help you.
You can do it in Bundle::boot:
use AppBundle\HttpFoundation\File\MimeType\MyCustomMimeTypeGuesser;
use Symfony\Component\HttpFoundation\File\MimeType\MimeTypeGuesser;
use Symfony\Component\HttpKernel\Bundle\Bundle;
class AppBundle extends Bundle
{
/**
* {#inheritdoc}
*/
public function boot()
{
parent::boot();
MimeTypeGuesser::getInstance()->register(new MyCustomMimeTypeGuesser());
}
...
}
This will be called every time the Kernel boots.
If you do it in Bundle::build it would not work, because the call needs to happen at runtime.

Can I implement my own Symfony2 annotations easily?

Is there anything in the Symfony annotations modules that allow me to use them for other uses?
I know for #Route and #Method you need to extend existing libraries, so its just not that easy i'm guessing.
Currently, i'm working with the JS History API, and would LOVE to put the popState data for my JS files in the annotations. So they are already available when the routing generates the URL.
Q Doesn't this makes sense to have a, HTML5 annotated title, or some attribute here? It would be great to have the ability to define this data, as annotated, right next to the already existing route name and stuff.
Q Is there anybody that has tweaked with the annotations before?
I wanted to clarify my intentions here as I think I left out some crucial details (the mention of History API) for understanding my use case.
There is a few SPA front ends that have been integrated through a front-end bundle, and this connected via AJAX calls to a backend bundle which was a straight RESTful API, with the addition of a very fun-to-develop PHP API class I made that intereprets and processes (routes) the AJAX in a fashion that directly executes other PHP class controller `methods.
I use a lot of ajax for this Symfony 2 app (fosjsrouter) to handle routing. So instead of URLs triggering the routes and actions, the SPA click event fires off AJAX to the back end router, with a large JSON payload, not limited to PHP control parameter's (class/method/var names), and data sets.
OK, so getting back on track; Given the above scenario; In the JS class object end of the router, inside this I thought it was the best place to add some JS History API functionality to it, (state, back button, etc.)
The above class can be called if a history flag was called, which could become responsible for assigning initial state data. Primarily, this is because the JSON data object that's being around in this JS method contains already a lot of the crucial route data, and param information for that route needed in the backend PHP, which comes from the annotations.
So the idea is if I add accessibility for a history state title and URL to the annotations, then I will have access to that information right there available to define the initial state, if flagged, right inside the an ajax.done(), inside this main JS routing method.
Now we can pass state back and forth two ways between the db and realtime client-side async. You can use an observer, or anything, from there front-end, and jobs/queues on the backend to keep it fully reactive. (use React too :-))
EDIT I'm not so sure that's what I was thinking, it looks like its making me set the values of the title and url for this inside the return statement of the PHP function, where I want it set in the annotation (see return 'Matthias Noback';)
So I'm trying this, but where do I set these titles at?
<?php
namespace Blah\CoreBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
/**
* #Annotation
*/
class HistoryAnnotationController
{
//history state params are out properties here..
/**
* #var
*/
private $url;
/**
* #var
*/
private $title;
/**
*
*/
public function __construct()
{
}
/**
* #return mixed
*/
public function getTitle()
{
return $this->title;
}
/**
* #return mixed
*/
public function getUrl()
{
return $this->url;
}
}
I want to set it WAY back here, so the ajax that calls this route has access to it.. (look for #historyApiTitle in this code, etc..)
<?php
namespace Blah\Bundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller,
Symfony\Component\HttpFoundation\JsonResponse,
Sensio\Bundle\FrameworkExtraBundle\Configuration\Method,
Sensio\Bundle\FrameworkExtraBundle\Configuration\Route,
Sensio\Bundle\FrameworkExtraBundle\Configuration\Template,
Blah\Bundle\Entity\Test,
Doctrine\ORM\Query; //for hydration
class StuffController
{
/**
* #Route("/some/route/name/{test}", name="some_route_name", options={"expose"=true})
* #param $test
* #return mixed
* #historyApiTitle('This is the get something page')
* #historyApiUrl('/get_something')
*/
public function getSomethingAction($test)
{
$em = $this->getDoctrine()->getManager();
$dql = "
SELECT s
FROM BlahBundle:Stuff s
WHERE s.test = :test";
$query = $em->createQuery($dql);
$query->setParameter('test', $test);
$paginator = $this->get('knp_paginator');
$pagination = $paginator->paginate($query,
$this->get('request')->query->get('page', 1), 1000);
return $this->render('BlahBundle:Stuff:get_something.html.twig', array('pagination' => $pagination));
}
}
Q So looking at these TWO code examples, how do I connect the dots between the two to get this to work?
Yes you can annotations classes you can follow the following tutorial Creating Custom annotations Classes
Basic rules are the follows:
Your class should have the #Annotation -phpdoc comment
/**
* #Annotation
*/
class CustomAnnotation
{
public function __construct($options) {}
}
In Your Needed class just use it in standard way;
class Person
{
/**
* #CustomAnnotation("option")
*/
public function getName()
{
return 'some stuff';
}
}
You should looks at the AOPBundle, it allows you to do treatement from your personnals annotations. But I don't thinks trying to do annotations in the view is a good idea. You need to parse the javascript with php, and it sounds bad.

Using convention over configuration in Symfony2 controllers/views

I have the following Symfony controller:
/**
* Says thanks to the user for signing up.
*
* #Route("/thanks", name="user")
* #Template()
*/
public function thanksAction()
{
return $this->render('VNNPressboxBundle:User:thanks.html.twig');
}
If I don't include the return statement, I get an error saying the controller must return a response. It's interesting that I have to manually specify which template my action needs to use, considering Symfony could easily figure that out based on my controller and action. Plus that's how Symfony 1.x worked.
I have to imagine that I'm missing something. It doesn't seem like they would apply the convention over configuration concept in Symfony 1.x and then abandon it in Symfony >= 2.0.
Is it possible to tell Symfony to figure out which template to use based on my controller and action, and if so, how?
You have to return something. You're using #Template annotation so you don't have to render the response but you still have to return an array of parameters for the template (in your case empty):
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
/**
* Says thanks to the user for signing up.
*
* #Route("/thanks", name="user")
* #Template()
*/
public function thanksAction()
{
return array();
}
Read more on #Template annotation in the docs: http://symfony.com/doc/current/bundles/SensioFrameworkExtraBundle/annotations/view.html
P.S. Don't compare symfony 1.x to Symfony 2.x. These are two different frameworks. Symfony 2 favors being explicit over magic.
Return an array. In your case it'll be an empty array, but normally you would fill it with variables you want to pass to a template.
