Joyful Development with Symfony 3

<3

I just flooded another thread here with an unneeded panicking comment, so I want to leave some positivity too :) I am an English-Polish translator desperately trying to morph into a web devel. This course is priceless help after I struggled to understand OOP and SF during a weekend course AND to keep my job. Also, I am a hard-of-hearing person with very little auditory training in English but I absolutely get what you are saying in the witty videos! Thank you for caring about the sound quality and providing the script for those of us who don't even see a point in having headphones at home :)

Well, you just made my day! I'm *so* happy you found the tutorials useful and fun *and* that the scripts were helpful! It's really important to us to make those available :). Good luck on your journey - becoming a webdev is not an "easy" task, which is why it's so rewarding.

Cheers!

Fatal error: Call to a member function getReceiver() on null in C:\xampp\htdocs\vendor\symfony\symfony\src\Symfony\Component\Security\Core\Authentication\Token\UserCheck.php on line 36

public function sanitize($feeder) {

$user = $feeder->getReceiver();

Hey May,

Could you provide a bit more context? Do you have a problem? Is it a fix? What course exactly is it related to? Code is meanless without description :)

Thanks!

hello i have this exact same problem with a script im working on... and i really need your help with it.. my email is patorikky@gmail.com....just send me an email so that we can engage in a discussion from there....or you can send me a whatsapp text +2349025627930 it'll be easier for us to communicate there

Hi Michal!

Yes and now :). Many of the fundamental concepts (routing, controllers, response, services) will be covered in both, though updated for any changes that have happened in Symfony 3 (usually pretty minor for those core concepts). But, the Symfony 3 tutorials are also a total rewrite: a new project that will cover some new concepts (like API stuff) that are a lot more important than they were years ago. The Symfony 2 tutorials are still great (and very deep), but we'll update and deprecate them one-by-one. I'm actually really excited about all of this :).

Cheers!

weaverryan my apologies for hijacking the post but I need your help and experience on something I am working on related to FOSUser, can you have an eye on to this post (http://stackoverflow.com/qu... in SO when you have a chance?

Hi there! That's quite the long, complex SO question :). If you put the code you're working on up on GitHub, it'll be much easier for me or someone else to exactly pinpoint the issue.

Cheers!

I have one confusion. If I pay now for all Symfony 2 tutorial (1 to 4), whether I have to pay again for Symfony 3 tutorial when it is released?

Hey Vladimir!

Yes, if you buy the individual Symfony 2 tutorials, then you would need to pay again for the Symfony 3 tutorials - the new ones are completely re-created from scratch. The first Symfony 3 tutorial is already (and free!) and we hope to start getting the additional Symfony 3 tutorials out over the next month so that you won't have to choose - apologies for that :). If you have a subscription, then you'll of course get access to everything that is out while you have your membership.

Cheers!

Hi, I´m having an error when I follow the steps on video: JSON Responses + Route Generation.

The error is Variable "notes" does not exist in genus\show.html.twig at line 25
500 Internal Server Error - Twig_Error_Runtime

I can´t solve it. I copy the docs from the tutorial. Can you give me some clue?

Hi Miguel!

You're doing fine - in the JSON Responses + Route Generation chapter, we remove the `$notes` variable in the render call in showAction(), and this temporarily breaks the "show" page (while we're working on the JSON endpoint). But, we fix this in the last chapter by removing that variable in the Twig template and populating it dynamically with JavaScript.

I hope that helps - I didn't mean to confuse anyone :)

There is a continuation of this tutorial ? Can I give me url to this ? I'll to learn more about symfony and I love this tutorial

Hey Luciano!

Yes, you can check the Symfony Fundamentals: Bundles, Configuration & Environments next.
A list of all subsequent courses is here: https://knpuniversity.com/t... .

Cheers!

Thank you Victor =)

Hi, Is code for project from these tutorials (symfony3) available in github?

Hey Paweł C.!

The code isn't available on GitHub, but you can download the course code from any of the video pages - it will contain a zip file with both the starting code for the tutorial and the finished code. For the first tutorial, this is available for everyone. For the other tutorials, you need to be a subscriber to download it :).

Cheers!

Expected value of type "AppBundle\Entity\Membre" for association field "AppBundle\Entity\Groupe#$membres", got "Doctrine\Common\Collections\ArrayCollection" instead.
any one help me please

Hey Ghada,

Can you give us a bit more context? What are you doing exactly when seeing this error? It looks like you pass an ArrayCollection instance instead of Member entity somewhere, but difficult to say where exactly. See the error line and please double check the code there.

Cheers!

me gusta symfony

Sin duda el mejor framework!

I want more! great tutorial ! :)

Within the next few days :)

Eventually, the 2.4+ courses will be removed from the "Symfony" track - this will happen once we have enough updated Symfony 3 tutorials.

Is Symfony 3 really ready for production sites?

Absolutely - it went stable at the end of November and actually has the same features as 2.8 - the only difference is that the deprecated features were removed. It's very stable :)

But keep in mind not all vendor bundles compatible with Symfony 3.0 yet :)

Nice, refreshing tutorial.

Thanks so much Ryan!
We don't need Laracasts, we've Ryan, Leanna and KNPLabs! ^ ^

cool thats my weekend fun sorted

congratulation

wow! I din't knew ReactJS was that 'reactive', you edit a file on the fly and page is... receiving a live feed? Awesome! Thank you guys.

Well, I am cheating a little bit - but the ReactJS does the same "cheat" :). There is some polling going on in the background to check for updates. But of course, you could also hook this up to get the same behavior without polling. Either way, it works pretty awesome - I have a lot of fun with React.

Thanks , really good tutorial. but i have some question. when you are rendering JSON string you get really pretty string with black property key and green values. when i rendered it , i just got simple html file with ugly JSON string. not colors , not line breaking , not spacing , am i done something wrong?

Hi, Levan! Rean has intelled some JSON viewer chrome plugin. I'm not sure what exactly plugin Rean has installed but you can install in Firefox and Google Chrome a plugin called: JSONView (Firefox and Chrome) or JSON Formatter (Chrome).

https://chrome.google.com/w...

You nailed it - I have JSONView installed - it makes my JSON look pretty :).

ah thank you very much!

Hello Felipe!
Thank you very much.

Hey Felipe and felipsmartins ,

Yes, the JSONView plugin for Google Chrome is exactly what we have in our screencasts!

Cheers!

How to upload an image in symfony with configuration as yml?

Hey Niel!

I'm not sure I understand your question - I like using VichUploaderBundle for uploading items to the site, but there is also some information about uploading on Symfony.com. I'm not sure what you mean by yml configuration - but please feel free to clarify :)

Cheers!

Thanks :)

I'd love to see an example of this without babel and have the js compiled using something like webpack.

That's beyond the scope of this tutorial (I wanted to only *touch* React), but it's definitely a good suggestion for a possible future tutorial that talks more about React itself :). Cheers Trent!

Hello, it there any upgrade for the part of login form and security in Symfony 3?

Hey Léo! There will be soon: http://knpuniversity.com/sc.... Cheers!

Great tutorial. Thanks! :)

Hello Ryan, after a year I came back to symfony and realized that symfony3 has been released. I'm wondering if your other videos for Symfony2 are still good to follow or there are some deprecated/old features that are not recommended to keep using.

I specially refer to the Login Form part

Thanks for your time!
