Great tutorial, as ever and has definitely helped me understand what Symfony is doing under the hood. I've now just got to work out how I'd ever make use of this knowledge in practice - what sort of edge cases, I'd need to consider.... 🤔

Hey Authoritas

They main reason of this tutorial is for you to know what's really happening under the hood, and how things works so you get more comfortable when working with Symfony. It's like unveiling the Symfony magic :)

Cheers!

Wow! This tutorial was a great one. I wonder how you crank out these high quality tutorials and doing so much for the community in general as well as coding and maintaining symfony. I mean - you must have so much work to do - that I feel kinda bad for saying: "I barely can't wait for the next deep dive tutorial no matter what area of symfony will be covered!"

Hey Michael B.!

Haha - thank you for the kind words ❤️. I do stay pretty busy ;). But also, many other people do the less-obvious work around Symfony... while I get to run around doing the *more* obvious stuff. Anyways, these types of messages make my day - thanks for dropping it!

Cheers!

I feel powerful after watching this tutorial. However I feel like I need to know more about containers, sessions and their life cycle. Is there an upcoming Deep dive tutorial about that soon?

|

MolloKhan SFCASTS FaresG 5 years ago edited

Hey FaresG

Yeah! This tutorial is awesome. At this point, we're not working on another deep-dive tutorial but we already have one in mind. It would be about the Container

Cheers!

Thank's a lot for this tutorial !!!! Exactly what I dreamed for ! Ryan you are my hero ! What's about the Security component ? And the containers ?

Hey Matheo D.

We're glad to hear that you liked this tutorial :)
At the moment we don't have a "deep-dive" Security tutorial but we still cover that topic in this course: https://symfonycasts.com/sc...
The next "deep-dive" course would be about the container but I know a release date yet. What I can offer you is this tutorial https://symfonycasts.com/sc... it is old but the core concepts haven't change

Cheers!
