Intro to Services

reemplace

$templating = $this->container->get('templating');
by
$templating=$this->container->has('templating');

Gracias !!!

Hey Mohit

As far as I know the "Templating" service was disabled for Symfony 3.4 version, to verify this, you can run: "$ php bin/console debug:container templating" or you can try to actually use it (ignoring the fact that you don't have autocompletion).
If that's the case, well, you should not be worry too much about it, because you can use "$this->render()" function at any controller that inherits from Symfony's base controller

Cheers!

Hi Diego Aguiar, Thanks for the help , but composer install doesn't fixed anything in my case. I am still getting service not found error.I am using symfony 3.4.4 and PhpStorm 2017.3.4 . In autocompletion I am getting 2 option for templating service , templating.helper.logout_url and templating.helper.security !!

Hey Mohit

Which version of PhpStorm and Symfony are you using? Remember that you need to activate Symfony's plugin first
Some times my index is all wrong and I fix it by running "$ composer install", it may work for you as well.

Cheers!

While writing $templating = $this->container->get('templating');(1:55) no autocompletion and also shows missing service warning even after excluding cache folder!! What to do ?

I suppose the issue has finished just to say that if i put in the container->get('templating.engine.twig') and not the alias 'templating' it works fine for me!

Yes! I'm glad to hear that you could fix your problem :)
Thanks for sharing your solution

cheers!

Even better solution found!

After I figured out the cache problem....got into the templating section of aqua_notes and found HEY Woah! The style sheets, images and js were not loading when viewing the page using my xampp server.

Figured it out. you have to set up the virtual host directive a little differently than most info on the web will tell you..then Symfony works and plays great with Xammp. Here's an example vhost config for a project called my-project. The form validation here on Disqus might screw up the example but we'll try.

Just as I thought....the double ="' s are not part of the solution, that is the form validation in Disqus stepping in for possible protection for the forward slashes and greater sign symbol, but you get the picture.

<virtualhost my-project:80="">
DocumentRoot "C:/xampp/htdocs/my-project/web"
ServerName my-project
<directory c:="" xampp="" htdocs="" my-project="" web="">
AllowOverride None
Order Allow,Deny
Allow from All
Options FollowSymlinks
<ifmodule mod_rewrite.c="">
Options -MultiViews
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ app.php [QSA,L]
</ifmodule>
</directory>
ErrorLog "logs/my-project-error.log"
CustomLog "logs/my-project-access.log" common
</virtualhost>

Just make sure the app.dev Kernel directive "prod" is set to false and your good to go!

Hope this helps those windows xammp user struggling to get things up and running.

Have a great day!

That is! You were hitting production, that's why everything was getting cached. Nice work man :)

Cheers!

Think I figured out the cache problem....haven't had it since i changed the vhost declaration...document path was project/web/ and after i added app_dev.php to it everything works great (so far...knock on wood) .

without the app_dev.php at the end I believe it was xampp was trying to use the production version app.php and that was causing a conflict in apache.

Yeah! :)
Have A Great Day!

Hmm, interesting, makes me wonder if you have some kind of cache activated, or if you apache is caching some files by default

Running xampp with php 7.2 straight out of the box and has worked for wordpress installs(non-bitnami app installs).

It only seems to have an effect when I change a controller and not any of the twigs.

Have a Great Day

Hey Kaira S

Thanks for sharing your findings! I bet more than one will find them helpful :)

About *2*: While in dev environment you should not need to clear cache that often, I'm not sure if there is something special with XAMPP because I'm on ubuntu, but *maybe* you have something odd in your configuration

Have a nice day

lol...thats ok....used to beating my head against something every time I start something new.

Did learn a couple things here and there.
1. You can't open a symfony project on xampp without first declaring a virtual host for it since the web root is web(xampp requires vhost setup for it like so)
<virtualhost genus="">
DocumentRoot "G:/xampp/htdocs/genus/web/"
ServerName genus
</virtualhost>

then a host domain of 127.0.0.1 genus
(that is what works for me..since I have multiple projects going.)

2. Clearing the cache is really important when making changes, else xampp will not see the changes most of the time.

Just a few tidbits I thought might help someone else....

Great course by the way...Love it!

Hey Kaira S!

Bah.... sorry about that - didn't mean to mislead :D. But, I hope your perfectionist at least made you learn some great stuff while digging!

Cheers!

Finally after 5 days of beating my head against the scattered documentation wall, i found the solution (for my setup anyway) maybe it will help others.

Update: Okay(DuhMe)...if i'd only watched the video in the next chapter Ryan shows this fix but, I wanted to get things working properly before advancing to the next chapter...(The perfectionist in me i guess....:) )

Found @ https://symfony.com/doc/2.8...

I'm running SF 3.4 and this solution works for it!

replace:

$templating = $this->container->get('templating');
$html = $templating->render('genus/show.html.twig',
[
'name' => $genusName
]);
return new Response($html);

with:

return $this->render('genus/show.html.twig', [ 'name' => $genusName ]);

I hope this helps someone else,
Happy Coding

+1 good tip! In 3.4, that config was removed, as the templating component is not being "recommended" anymore. But, there's no problem with activating it. It's just that, as we move forward, less and less bundles will use this component. So, at some point, you won't need it (things are now using Twig directly).

Cheers!

If you run into a problem that Symfony v3.4 tells you about non-existent service "templating":

You have requested a non-existent service "templating". Did you mean one of these: 
"templating.helper.logout_url", "templating.helper.security"?

you need to add the following configuration into your app/config/config.yml:

framework:
    templating:
        engines: ['twig']

(Note: there probably already is "framework" section so just add the "templating: engines: ['twig']" part into it.)

Hey Cleo,

Excluding cache depends on your IDE, you need to Google for it to find a solution for *your* IDE. I think you can find something useful on StackOverflow. Anyway, it's not a big deal to exclude the cache dir, so you can skip this step if you can't find how to do it. But PhpStorm is our favorite PHP IDE, and with Symfony plugin it's the best for Symfony, I really advise you to try it. You can check its most useful features in our screencast: Lean and Mean Dev with PhpStorm (for Symfony).

Cheers!

Thanks for tutorials.
Anyway.. I didn't use code editor like yours. How to exclude cache then?

Looks like it just got fixed - we just need to wait for a new version of the plugin to be released! Woohoo!

It should work, because it is not Symfony Plugin feature but Core PhpStorm one :) Make sure you store the reference to the templating service in variable first. Or maybe I was wrong with interface, try to reference service class directly, it should be "\Symfony\Bundle\TwigBundle\TwigEngine" as I know:

/** @var \Symfony\Bundle\TwigBundle\TwigEngine $templating */
$templating = $this->container->get('templating');

// And you will get autocompletion here
$templating->render();

Cheers!

thX! I would look forward to undrestand how to fix it :)

Thank you for helping but it didn't work. I guess I'm just gonna ignore it for now as weaverryan said since I'm going to use the sortcut for it:
$this->render();

Hey Ali,

Good catch! Until it will be fixed, you can use annotation above the variable to get autocompletion temporarily:

/** @var \Symfony\Bundle\FrameworkBundle\Templating\EngineInterface $templating */
$templating = $this->container->get('templating');

Cheers!

Hey Ali Niaki!

Actually, I see the same behavior in Symfony 3.3! And it looks like a bug in the PhpStorm plugin - I've opened an issue: https://github.com/Haehnche.... For now... ignore it! Hopefully it's an easy fix in the plugin :).

Cheers!

Same in ControllerTrait.php
phpstrom is not finding 'templating' in that file too, for example in render function line 231:

protected function render($view, array $parameters = array(), Response $response = null)
...
return $this->container->get('templating')->renderResponse($view, $parameters, $response);
...

get('templating'): missing service

Hey,
Yes. It's just the autocompletion that is not working and the code actually works. Also I checked another service, for example "mailer" and autocompletion worked:
$this->container->get('mailer');
However as I said, phpstrom is not suggesting me 'templating'.

Hey Ali,

Is it only autocompletion problems, I mean this code works well, you just don't have autocompletion in PhpStorm? Does this problem only for "templating" service or you have the same for other services? Do you have the latest version of Symfony Plugin and PhpStorm?

Cheers!

$templating = $this->container->get('templating'); phpstrom shows "missing service"
I cleared the cache and cache folder IS excluded. I don't know how to fix this issue and I'd be glad if you can help me.

It works fine in version 3.0 but not in 3.3 and I have no idea why!

I'll check it, thank you very much!

Hey Tomislav!

Can you double check that your template lives in "app/Resources/views/genus/show.html.twig"
if so, then you might be running in production mode, while in production, you have to clear cache every time you make a modification, but in this case you want to run in development mode, so you can forget about those pesky problems

Have a nice day!

Hey Ross! I hope you had a great weekend :)

Yeah the config files can be .yml or .xml, in your case are .yml
Your configuration looks good to me, I'm not sure what is causing it to don't find the service
Can you double check that you are not running in production mode ?
In a controller method just do this, so you can be 100% sure:

$env = $this->get('kernel')->getEnvironment();
dump($env); die;

Also run again composer install and clear the cache, just in case

"I have aslo noticed, in my src folder, i dont have AppBundle\Directory\ClassName?"
You don't have it because is just an example of how to point to a service class, by writting the full namespace of that class

Cheers!

Thank you for tutorials!

Here's my problem:

“
Unable to find template "genus/show.html.twig" (looked into: D:\xampp\htdocs\novi_symfony_projekt\app/Resources/views, D:\xampp\htdocs\novi_symfony_projekt\vendor\symfony\symfony\src\Symfony\Bridge\Twig/Resources/views/Form).

I have aslo noticed, in my src folder, i dont have AppBundle\Directory\ClassName? just AppBundle\Controller, if that helps.

Hows it going Diego, thanks for the reply! What config files? config.yml? i continued with the tutorial and have also implemented the database, but i am still geting the missing service, aslo put services.yml at the end of the post.

namespace AppBundle\Controller;

class BibliographyController extends Controller
{
    /**

    public function newAction()//order of route...
    {//adding to database
        $bib = new Bibliography();
        $bib->setName('Ross');
        $bib->setDif('Test');

        $entityManager = $this->getDoctrine()->getManager();//get manager
        $entityManager->persist($bib);//tell to save
        $entityManager->flush();// commit to the addition


        return new Response('<html><body>Added Ross to database</body></html>');
    }



    /**
     * @Route("/Bibliography/{wildcard}")
     */
    public function showAction($wildcard)
    {
        $notes = [
          'New entry: Latest technology in 3d accelerated hardware',
            'Old entry: A study on the latest in game graphics',
            'Admin entry: Update database'

Hey Ross!

If you are extending from BaseController (I can see you do) you can use "$this->render()" directly, anyways that error you are experimenting is kind of weird, are you using Symfony Standard Edition ?
If you do, maybe there is a problem with your configuration, I'd like to see your configuration files so I can check if everything is ok.

Have a nice day!

Hows it going, im getting a missing service on 'templating', Ive excluded the cache directory aswell. If i continue with the tutorial , the site operates, but, i still have mising service?

namespace AppBundle\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;

class BibliographyController extends Controller
{
/**
* @Route("/Bibliography/{wildcard}")
*/
public function showAction($wildcard)
{
$templating = $this->container->get('templating');
$html = $templating->render('Bibliography/show.html.twig',
[
'name'=>$wildcard
]);
return new Response($html);
}
}

Hey, Jelle!

BTW, if you would love to be a PhpStorm beta tester, you could use it for free. Check PhpStorm Early Access Program, each month you will be able to download a new build of PhpStorm beta. It's a new fully featured version of PhpStorm, which will be released in the future. You need to update it to each time when new build is released to renew your trial licence.

Cheers!

Aah Yes, I see it now! Thanks a bunch! I would love to use PHPstorm if it was free to use, in contrast to Netbeans, that's why my choice has fallen on the last mentioned

Hey Jelle!

Ya know, the hardest things to track down are the smallest mistakes. And this is small! :)

Here's the problem:

// you have
$templating->$this->container->get('templating');

// you should have
$templating = $this->container->get('templating');

That's it :). Hence the undefined variable error - it thinks you're trying to use a $templating variable, not set one! Your editor should highlight this for you with an error. I like PhpStorm better than NetBeans, but that's a solid editor - check to see if there's any red highlighting around this area that would help you spot things like this.

Cheers!

Great tutorial, one problem though, I get "Notice: Undefined variable: templating"

And an exception:
Uncaught PHP Exception Symfony\Component\Debug\Exception\ContextErrorException: "Notice: Undefined variable: templating" at D:\media\sandbox\test\symfony2016\src\AppBundle\Controller\GenusController.php line 23
Context: [exception => Object(Symfony\Component\Debug\Exception\ContextErrorException)]

I've followed your tutorial and this is my controller code:

namespace AppBundle\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;

use Symfony\Component\HttpFoundation\Response;

* @Route("/genus/{genusName}")
* */
public function showAction($genusName){
$templating->$this->container->get('templating');
$html = $templating->render('genus/show.html.twig', [
'name' => $genusName
]);
I don't use phpstorm but Netbeans, perhaps I used a wrong namespace?

Ok, thanks !

Hi Konrad!

Good job debugging :). The problem is that auto-complete will suggest *both* classes. For PhpStorm, it sees 2 classes that are named Controller. It doesn't know which one is the correct class and which one is the incorrect class - it simply suggests to you both classes that are called "Controller". The one in HttpKernel\Tests is just an internal helper class for helping core Symfony run its own tests. But, PhpStorm doesn't know this.

Usually, when you use auto-complete, there is only 1 matching class name, but sometimes there are multiple, so you need to be careful to choose the correct one. Another example is Symfony's Response class. There are two: one in the HttpFoundation component (this is the one you want) and one in the BrowserKit component (not the one you want).

I hope this clarifies!

Hi,
Firstly great tuturial ;)
Secondly I did all the steps but I get
"Attempted to load class "Controller" from namespace "Symfony\Component\HttpKernel\Tests".
Did you forget a "use" statement for "Symfony\Bundle\FrameworkBundle\Controller\Controller"?"

my use statement after autocompletion is use Symfony\Component\HttpKernel\Tests\Controller;
and in this tutorial it's use Symfony\Bundle\FrameworkBundle\Controller\Controller;
what's the correct way?

---------Edit-------------

OK, pasted the second one and it works - but still , why does my autcompletion gives me the wrong one?

Oh my, sorry I didn't notice that :) it's now working thanks for the help!

Hi Jay!

You're getting some really good errors - because these are some of the most common errors. So once you learn how to read them, you'll be dangerous :).

For this error, Symfony is literally saying: "I looked through all of your routes, but didn't find any that match the URL /". Remember, you can get a list of *all* of the routes you've built by running:

bin/console debug:router

In this case, we have not (at this point) created an route for the URL "/". Try changing the URL in your browser to http://localhost:8000/genus/octopus.

You may have other errors when you get to that page, but this is definitely the cause of *this* error. About the auto-completing, do you have the Symfony plugin installed *and* enabled for this project?

Cheers!

Thanks for the reply! the path is correct and now i'm getting this error:
No route found for "GET /"
404 Not Found - NotFoundHttpException
1 linked Exception:
ResourceNotFoundException ».

The cache is already mark as excluded but the auto-complete in get('templating') doesn't appear even when i'm pressing ctrl + spacebar and it says "No suggestions".
i still get the error even if i change the code into this:
return $this->render('genus/show.html.twig', [
'name' => $genusName
]);

Hi Jay!

You should ignore the "Typo" - that's PhpStorm being *too* helpful. It literally is saying "The word templating isn't a real English word, maybe it's a typo?". It *is* the correct "service id" to use :).

About your error, you can see that the templating service is *trying* render your template, but it can't find it. This literally means that it's looking for it at app/Resources/views/genus/show.html.twig, but it doesn't see a file there. Double-check that you have that file (and that it's in the right location) - that's probably the error. But let me know either way

Cheers!

why am i getting this error "Typo: In word 'templating'
Spellchecker inspection helps locate typos and misspelling in your code, comments and literals, and fix them in one click."

i get that in this code:
$templating = $this->container->get('templating');

i followed the instruction but the auto complete in templating didnt show.
and this is the error when i load the page:

Unable to find template "genus/show.html.twig" (looked into: C:\wamp\bin\aqua_note\app/Resources/views, C:\wamp\bin\aqua_note\vendor\symfony\symfony\src\Symfony\Bridge\Twig/Resources/views/Form).
