Hi everyone,

has something changed in symfony 6 with the depenency injection?
The var_dump part doesn't work for me. Seems like the file is not loaded at all (I can type gibberish in this file, doesn't do anything).


namespace Xxx\SomeBundle\DependencyInjection;

use Symfony\Component\Config\FileLocator;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Loader\XmlFileLoader;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;

class XxxSomeExtension extends Extension
{
  public function load(array $configs, ContainerBuilder $container)
  {
    var_dump('lol');die;
  }
}

Thanks for your help.
David

Hi David, I experienced the same problem as you. My problem was that my bundle extended from AbstractBundle (which is the new syntax) and not from Bundle as shown in this video. If you extend from AbstractBundle, follow the instructions here

Hey David Schaller!

No, nothing has changed as far as I know - and this functionality is pretty core and unchanging. There are 2 possibilities:

A) Cache: you might need to manually rebuild your cache, then it'll hit your code. That shouldn't happen (the cache should be rebuilding itself when it detects that you modify this file), but it's possible something weird is happening.

B) For some reason your extension isn't being seen. The registration of the extension is actually handled by your bundle class. Well, not directly - but the base Bundle class that it extends. I'd open up that core class and add some debugging code in this method - https://github.com/symfony/... - to see what's going on.

Let me know what you find out :).

Cheers!

I found that I added XxxSomeBundleExtention instead of XxxSomeBundleExtention. Once I took out Bundle in the name it worked just fine.

Hey David,

when you delete the service in the config/services.yaml file of the application, then work the `var_dump'.

services:

KnpU\LoremIpsumBundle\KnpUIpsum: ~

triemli 6 years ago edited

Hi. As I right understand, I specify triemli\LoremIpsumBundle\TriemliLoremIpsumBundle::class => ['all' => true], in bundles.php

Then I have extension file https://pastebin.com/qPUGaqZM

So it should be already try to be loaded right? I just see normal web page.

|

Victor SFCASTS triemli 6 years ago

Hey WebAdequate,

Yep, but it's compiled, so you have to clear the cache first. Did you try to clear the cache? I'd recommend you manually remove var/cache/dev/ directory to clear the cache for dev (or for other env you use). Because bin/console cache:clear won't work as it will fail due to your die(); statement. Btw, if you run cache:clear command - you will find your die(); statement there, i.e. it should print "234" in your console :) Do you see this?

Cheers!

|

triemli Victor 6 years ago

Ok I found an error: Instead of TriemliLoremIpsumBundleExtension must be TriemliLoremIpsumExtension
I just hear "bundle name + extension". I would specify "bundle name minus 'Bundle' postfix"

|

Victor SFCASTS triemli 6 years ago

Hey WebAdequate,

Ah, a misprint! Good catch, I totally miss that part :) Thanks for sharing your solution with others!

Cheers!

triemli Victor 6 years ago edited

Hi again! Actually i'm always clear cache with manual remove.

So I have triemli\LoremIpsumBundle\TriemliLoremIpsumBundle::class => ['all' => true], in bundles.php
I have also class TriemliLoremIpsumBundle extends \Symfony\Component\HttpKernel\Bundle\Bundle
And this file https://pastebin.com/qPUGaqZM which is in DependencyInjection folder
refresh the page... it's successful loaded. The method load() wasn't called. ;[

Bertin 7 years ago edited

Hi there,

For our company we're trying to manage multiple bundles and have some questions
or need some best pratices or tips (hope you could help us).

#1 Bundles
Do you (or someone else) have some tips how we could manage/maintain/development these bundles. We're thinking of an development project where all bundles are loaded but with opportunities to maintain individuel bundles (does someone has experience with this kind of setup.

#2 Tools
Is there some tool where we could manage all projects like Symfony version, Bundle versions, code health, code errors, etc
Something like ManageWP for Wordpress.

|

Victor SFCASTS Bertin 7 years ago

Hey Bertinm!

Sorry for the delay!

1) Not sure I completely understand your question. Could you explain a bit more what you're trying to achieve here? Are you talking about open-source bundles? Or private bundles? Actually, Composer can work with private packages as well, it just need to have access (READ access at least) to your GitHub account where those bundles are hosted and it can install them without problems.

2) Unfortunately, I don't know a similar service personally. You probably may google for it, but can't give you any recommendations about them. I'd recommend you to look at SymfonyCloud: https://symfony.com/cloud/ - it's the best for Symfony apps. About code health - take a look at Symfony solution: https://insight.symfony.com/ . Or you can also check another one: Scrutinizer. What about monitoring - we love NewRelic. All this is a good stack, you can read more about them on their promo pages.

Cheers!

Our bundles are stored into a private repo (Bitbucket). Now we are maintaining all these bundles individual (each bundle is an separated folder). We are searching for a way to maintain these bundles something like git subtree and with automatich versioning, CI, etc.

Hope someone has experience with this kind of setup

|

Victor SFCASTS Bertin 7 years ago

Hey Bertin,

Oh, I see... It sounds exactly like Symfony team manages their repositories: they have subtree for each bundle/component, but it's readonly. All the work is going to happen in symfony/symfony repository. I think you can even spy their travis CI configuration as it's an OSS. What about automatic versioning? I know they use internal tool for merging, and probably for versioning as well, or maybe they do it manually. I think you can ask it in Symfony slack channel and get more context about it, here's the link: https://symfony.com/support

I hope this helps.

Cheers!

I get an error when i run the project's code as follows: "Attempted to call an undefined method named, hasBeenStarted" of class "Symfony\Component\HttpFoundation\Session\Session".

|

sadikoff Weli 7 years ago edited

Hi Weli

We investigated your problem and already fixed course code. There are 2 options for you

1) Re-download course code and start from the beginning
2) run "composer require symfony/http-kernel:4.0.12" (this will fix package versions used in course code)

I would prefer first option, because you are only on second chapter, but you are free to choose!

Cheers!

|

Victor SFCASTS Weli 7 years ago

Hey Weli,

Yeah, looks like this method was removed because it had been marked as internal. Probably the best solution is to try to upgrade your dependencies, see https://github.com/symfony/... for more information. Btw, you say that it happens in the code of this course you downloaded when follow instructions in README? Could you explain a bit more about when you see this error and what was your actions? Are you in start/ or finish/ directories?

Cheers!

how to create Bundle using command in symfony 4?

|

weaverryan SFCASTS Vishal P. 7 years ago

Hey @Vishal!

Great question! There is currently no way to generate a bundle using a command in Symfony 4. There is some discussion about this https://github.com/symfony/... - but it is not currently supported. And this is part, on purpose. In Symfony 4, you should never need to create a bundle in your application. The only purpose to a bundle is if you're creating re-usable code. And, in that case, it's probably better just to build it manually and add only the pieces that you need.

I hope that helps!

Cheers!

All great, but we should use try/catch blocks while XmlFileLoader tries to load a file...

Shing S. 8 years ago

Hi,

This is not really a question per se, I was trying out having config in php instead of yaml or xml.
After trying and figuring out for a long while,

php configs in symfony is just a php file with no classes, and readable with just
loadFromExtension()

Also a yaml or xml config file will override the php config file.
Is this correct or am i missing something?

Thank u.

|

Victor SFCASTS Shing S. 8 years ago

Hey Shing,

I have never used PHP configs :p but probably it's correct to say that different config formats will be merged into one big config that is cached later. But of course, if you set the same config key in config.php and config.yaml or config.xml - the value will be overwritten. In theory - yes, the value you set in PHP config file will be overwritten with one from Yaml/XML. Why? Probably because in the english alphabet "Y" and "X" letters go after "P", that why the file order for reading will be the next:
- config.Php
- config.Xml
- config.Yaml

But I'd not recommend you mixing different config formats. Choose one and use it. Well, at least do not use the same file names for different formats to do not confuse system, other devs and yourself. However, having config.php and bundle.yaml files are OK I think. But I'd stick to a one format in whole the system.

And yes, it's just a PHP file, but you should at least have access to $loader variable from it like showed here: https://symfony.com/doc/cur...

Cheers!

|

shing Victor 8 years ago

haha..Didnt consider the letters of file extension part of the order.

Yea, agree, mixing the config is not the easiest way to go. Just though some config might benefit from php for more flexibility. But let go of the idea, because its too messy to organise and test.

I also having the issue when refreshing the page, the page loads normaly.
I'am in dev mode, the bundle is registered in bundles.php, also added the lib/bundle/src to composer.json


#lib/MenuBundle/src
/**
 * BhamMenuBundle
 */

namespace Bham\MenuBundle;

use Symfony\Component\HttpKernel\Bundle\Bundle;

/**
 * Class BhamMenuBundle
 * @package Bham\MenuBundle
 */
class BhamMenuBundle extends Bundle {

}


#lib/MenuBundle/src/DependencyInjection
/**
 * BhamMenuExtension
 */

namespace Bham\MenuBundle\DependencyInjection;

use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;

class BhamMenuExtension extends Extension {

	/**
	 * Loads a specific configuration.
	 * @param array $configs
	 * @param ContainerBuilder $container
	 */
	public function load(array $configs, ContainerBuilder $container) {
		var_dump('ALIVE!');die;
	}
}

Does i miss something? I've cleared my cache and run the command composer dumpautoload

|

Victor SFCASTS Bertin 8 years ago

Hey Bertin,

I think you used incorrect namespace in your Extension class, it should be "Symfony\Component\DependencyInjection\Extension\Extension" instead of "Symfony\Component\HttpKernel\DependencyInjection\Extension". That's important and I think that's why your extension does not loaded, i.e. you just extends invalid class.

Cheers!

Dmitry V. Victor 7 years ago

Hi Victor!

Are you right with your comment? As this tutorial shows it must be used "Symfony\Component\HttpKernel\DependencyInjection\Extension"... And I see there's no difference which one is used, they both are called while Symfony loads its bundles.

|

Victor SFCASTS Dmitry V. 7 years ago

Hey Dmitry,

Oh, wait... you're right, it should be "Symfony\Component\HttpKernel\DependencyInjection\Extension" as we show in this screencast. And in turn, this class extends "Symfony\Component\DependencyInjection\Extension\Extension". So the problem was in the namespace, but not exactly as I thought.

Thanks for noticing it!

Cheers!

|

Bertin Victor 8 years ago

@Victor Bocarsky, it was the wrong namespace. Thx

Victor SFCASTS Bertin 7 years ago

Hey Bertin,

Great! And thanks for approving the fix, I think it might be helpful for others.

Hi,

I don't understand why when I refresh my page, it loads normally. I don't have the var_dump

Cheers,
Thx.

Greg

MolloKhan SFCASTS Gregory 8 years ago edited

Hey Gregory

"var_dump()" is native function from PHP, so you should have it :)
What I believe is that you are hitting the prod environment and that's why you can't see your changes without clearing the cache, or maybe you forgot to register the bundle?

Cheers!

|

Gregory MolloKhan 8 years ago

I known that my mistake I dont see the var_dump when I refresh the page ;)

|

MolloKhan SFCASTS Gregory 8 years ago

hehe, no worries

Can you double check that you can actually see the "profiler" bar at the bottom of the page, and that you registered the bundle in "config/bundles.php"
Also, just in case, try clearing the cache

|

Gregory MolloKhan 8 years ago

Ok I found it
I just forgot to remove the service in the service.yaml ;)
