Who would have thought that the concept of caches can be so easy. Thank you this helped me a lot.

[@GaryClarkeTech]

You're welcome. Hope you get to use the information.

[@luizneri]

I was looking for config and container components, but I'm glad I stumped here. Amazing video!

[@GaryClarkeTech]

Awesome, thank you!

[@vitiok78]

Great tutorial! Symfony is awesome and we absolutely need more tutorials like this on KZbin

[@GaryClarkeTech]

Thanks Victor. I appreciate your support 👍

[@PawelCyrklaf]

Great tutorial, I just need to implement some cache system in Symfony, so your tutorial will come in handy :D

[@GaryClarkeTech]

Awesome..glad it helped, Paweł. Check out the most recommended way of using it in a Symfony project in the part 2 video.

[@AnDre-ox6xl]

Thank you very much for this tutorial! Straight to the point.

[@GaryClarkeTech]

You're welcome..thanks for watching!

[@bakaleisanich]

Thanks for your lessons. Did not find a video about creating a simple api

[@GaryClarkeTech]

I've not done a creating an API video yet because it will be hard to do in just a couple of vids...so I'll most likely do a small series when I do it. I've not forgotten!

[@janhazincak7980]

Great tutorial. Many thanks Gary.

[@tracid2008]

Great work! I would love to see a tutorial for the messenger component.

[@GaryClarkeTech]

Thanks Daniel 👍I've put messenger on the list.

[@jasongoossens]

@@GaryClarkeTech May I ask what else is on the list? 😊

[@GaryClarkeTech]

@@jasongoossens It's become quite a big list! I've got REST API and more OOP stuff coming up

[@jasongoossens]

@@GaryClarkeTech Sounds interesting! I'm busy learning the inner workings of Symfony and in addition to the documentation, videos like yours are a real help!

For enabling memcached or redis adapters

[@GaryClarkeTech]

You can watch redis adapter in part 2: kzbin.info/www/bejne/jZuYmWaOhLWshqc

[@ElGovanni]

Hi Gary, great job but can I ask if You have any knowledge about deployment? I'd love to see if im correct what I'm doing with CD (for example with symfony, github actions and some VM).

[@GaryClarkeTech]

I have some deployment knowledge but, as far as CD + github actions is concerned, there are other guys on KZbin who are way more knowledgeable than me. It's not really my area of expertise.

[@MrGabishDe]

Hey Gary. Can you please make a video about symfony with docker ? Or are you only using symfony with symfonly cli ?

[@GaryClarkeTech]

I made this one a few months ago: kzbin.info/www/bejne/f4Wyn6OwoN-fj68 But a lot of the time in development I just use the Symfony - Docker integration from the docs with PHP on my machine..not in a container. I demo that with Redis in part 2 of this lesson.

[@parijke]

Hi Gary, again nice tut. I wondered why you inject the EntityManagerInterface instead of the StockRepository. Is it arbitrairy or do you do this with a special reason?

[@GaryClarkeTech]

Cheers Paul...it's something I've just not thought of doing. Injecting EM is just a habit that I do without really thinking about doing it any other way. Might give it a go in the future!

[@anstapol]

Hey Gary great video! Thank you for your work. About the cache component, how do you deal with unit tests that involves components that use cache? In my case it's a repository with heavy query I'm caching the result but when running test I can't pass them because the cache is somehow hitting but empty. So I don't have any results...

[@GaryClarkeTech]

Thanks Anton. It sounds like you could possibly be checking a different cache pool in your test than the one you are using in your code. If I get the chance, I'll make a recording on tests which hit the cache.

[@anstapol]

@@GaryClarkeTech Thank you very much for your answer. I was wrong the problem is with the fixtures not the cache. I used sqlite like you did in another tutorial and it's not importing all the fixtures and exits without an error, then I switched to mysql and it throws an error even that for dev environment it's working fine.

[@GaryClarkeTech]

@@anstapol Cache can be quite fiddly for tests. There can sometimes be things left in there even though you clear the cache at the end of each test. I usually add the tests that hit a cache to a group and exclude them from running unless I specifically require them.

[@sindro88]

Thank for your fantastic lessons. Can you do videos about implementation of Hexagonal Architecture in Symfony ?

[@GaryClarkeTech]

Thanks Alessandro 👍 Hexagonal Architecture is something I'm hearing more and more but I know little about it. When I do decide to learn more about it, I'll defo share what I learn!

[@sindro88]

@@GaryClarkeTech thank you so much

Not beginner friendly. Don't even understand anything
