WEBVTT NOTE Created by CaptionSync from Automatic Sync Technologies www.automaticsync.com 00:00:01.096 --> 00:00:04.536 align:middle Hats off for nearly making it through the first Symfony tutorial. 00:00:04.756 --> 00:00:08.246 align:middle You've taken a huge step toward building whatever you want on the web. 00:00:08.786 --> 00:00:13.526 align:middle To celebrate, I want to play with MakerBundle: Symfony's awesome tool for code generation. 00:00:13.916 --> 00:00:17.646 align:middle Let's get it installed: composer require symfony/maker-bundle -- 00:00:17.646 --> 00:00:23.616 align:middle dev We haven't seen that -- dev flag yet, but it's not that important. 00:00:24.336 --> 00:00:26.316 align:middle Move over and open composer.json. 00:00:26.316 --> 00:00:31.096 align:middle Thanks to the flag, instead of symfony/maker-bundle going 00:00:31.146 --> 00:00:35.276 align:middle under the require key, it was added down here under require-dev. 00:00:36.096 --> 00:00:39.526 align:middle By default, when you run composer install, it will download everything 00:00:39.526 --> 00:00:42.546 align:middle under both require and require-dev. 00:00:43.196 --> 00:00:47.586 align:middle But require-dev is meant for packages that don't need to be available on production: 00:00:47.936 --> 00:00:50.786 align:middle packages that you only need when you're developing locally. 00:00:51.286 --> 00:00:56.096 align:middle That's because, when you do deploy, if you want, you can tell Composer: Hey! 00:00:56.346 --> 00:01:01.576 align:middle Only install the packages under my require key: don't install the require-dev stuff. 00:01:01.576 --> 00:01:04.136 align:middle That can give you a small performance boost on production. 00:01:04.486 --> 00:01:06.096 align:middle But mostly, it's not a big deal. 00:01:06.716 --> 00:01:08.666 align:middle Now, we just installed a bundle. 00:01:08.996 --> 00:01:11.606 align:middle Do you remember the main thing that bundles give us? 00:01:11.996 --> 00:01:13.506 align:middle That's right: services. 00:01:14.016 --> 00:01:18.926 align:middle This time, the services that MakerBundle gave us are services that provide new console commands. 00:01:19.286 --> 00:01:20.396 align:middle Drumroll please. 00:01:21.166 --> 00:01:24.536 align:middle Run: php bin/console Or, actually, 00:01:24.536 --> 00:01:27.006 align:middle I'll start running symfony console, which is the same thing. 00:01:27.006 --> 00:01:31.906 align:middle Thanks to the new bundle, we have a ton of commands that start with make! 00:01:32.606 --> 00:01:35.736 align:middle Commands for generating a security system, making a controller, 00:01:35.856 --> 00:01:39.176 align:middle generating doctrine entities to talk to the database, forms, 00:01:39.176 --> 00:01:40.896 align:middle listeners, a registration form.... 00:01:41.056 --> 00:01:43.306 align:middle lots and lots of stuff! 00:01:43.306 --> 00:01:46.536 align:middle Let's use one of these to make our own custom console command. 00:01:47.056 --> 00:01:52.106 align:middle Run: symfony console make:command This will interactively ask us about our command. 00:01:52.396 --> 00:01:54.586 align:middle Let's call it: app:ship-report. 00:01:55.446 --> 00:02:01.116 align:middle Done! This created exactly one file: src/Command/ShipReportCommand.php. 00:02:01.116 --> 00:02:02.086 align:middle Let's go check that out! 00:02:06.386 --> 00:02:10.856 align:middle Cool! This is a normal class - it is a service, by the way - 00:02:11.086 --> 00:02:13.596 align:middle but with an attribute above: #[AsCommand]. 00:02:14.056 --> 00:02:15.906 align:middle This tells Symfony: Yo! 00:02:15.996 --> 00:02:17.106 align:middle See this service? 00:02:17.226 --> 00:02:22.536 align:middle It's not just a service: I would like you to include it in the list of console commands. 00:02:22.536 --> 00:02:26.186 align:middle The attribute includes the name of the command and a description. 00:02:26.626 --> 00:02:31.016 align:middle Then the class itself has a configure() method where we can add arguments and options. 00:02:31.626 --> 00:02:36.736 align:middle But the main part is that, when somebody calls this command, Symfony will call execute(). 00:02:37.326 --> 00:02:39.156 align:middle This $io variable is cool. 00:02:39.486 --> 00:02:45.136 align:middle It lets us output things - like $this->note() or $this->success() - with different styles. 00:02:45.356 --> 00:02:50.266 align:middle And though we don't see it here, we can also ask the user questions interactively. 00:02:50.786 --> 00:02:51.476 align:middle The best part? 00:02:51.726 --> 00:02:55.346 align:middle Just by creating this class, it's ready to use! 00:02:55.346 --> 00:03:01.396 align:middle Try it out: symfony console app:ship-report That's so cool! 00:03:01.686 --> 00:03:05.076 align:middle The message down here comes from the success message at the bottom of the command. 00:03:05.076 --> 00:03:10.126 align:middle And thanks to configure(), we have one argument called arg1. 00:03:10.666 --> 00:03:13.916 align:middle Arguments are string that we pass after the command, like: 00:03:13.916 --> 00:03:20.566 align:middle symfony console app:ship-report ryan It says: You passed an argument: ryan ... 00:03:20.896 --> 00:03:22.906 align:middle which comes from this spot in the command. 00:03:23.486 --> 00:03:25.816 align:middle There are a lot of fun things you can do with commands... 00:03:26.036 --> 00:03:27.496 align:middle and I want to play with one of them. 00:03:28.156 --> 00:03:32.566 align:middle One of the superpowers of the $io object is to create animated progress bars. 00:03:33.086 --> 00:03:34.726 align:middle Imagine we're building a ship report... 00:03:34.966 --> 00:03:36.956 align:middle and it requires some heavy queries. 00:03:36.956 --> 00:03:39.496 align:middle So we want to show a progress bar on the screen. 00:03:40.156 --> 00:03:44.506 align:middle To do that, say $io->progressStart() and pass it however many rows 00:03:44.506 --> 00:03:46.386 align:middle of data we're looping through and handling. 00:03:46.856 --> 00:03:50.086 align:middle Let's pretend we're looping over 100 rows of data for this report. 00:03:50.086 --> 00:03:54.036 align:middle Instead of looping over real data, create a fake loop with for. 00:03:55.126 --> 00:03:57.896 align:middle I'm even going to include the $i variable in the middle! 00:03:59.226 --> 00:04:04.166 align:middle Inside, to advance the progress bar, say $io->advance(). 00:04:04.166 --> 00:04:07.566 align:middle Then, here is where we would do our heavy query or heavy work. 00:04:07.566 --> 00:04:11.546 align:middle Fake that with a usleep(10000) to create a short pause. 00:04:11.546 --> 00:04:15.616 align:middle After the loop, finish with $io->progressFinish(). 00:04:16.326 --> 00:04:16.806 align:middle That's it! 00:04:16.806 --> 00:04:22.566 align:middle Spin over and give that a try: Oh, that is so cool. 00:04:23.186 --> 00:04:24.566 align:middle And... that's it people! 00:04:24.956 --> 00:04:26.336 align:middle Give yourself a high five... 00:04:26.336 --> 00:04:29.286 align:middle or, better, surprise a co-worker with a jumping high five! 00:04:29.686 --> 00:04:32.736 align:middle Then celebrate with a well-deserved beer, tea, 00:04:32.986 --> 00:04:35.636 align:middle walk around the block or frisbee match with your dog. 00:04:36.086 --> 00:04:36.476 align:middle Because... 00:04:36.586 --> 00:04:37.286 align:middle you did it! 00:04:37.546 --> 00:04:40.726 align:middle You took the first big step into being dangerous with Symfony. 00:04:41.186 --> 00:04:45.836 align:middle Then, come back and try this stuff out: play with it, build a blog, 00:04:45.836 --> 00:04:48.536 align:middle create a few static pages, anything. 00:04:48.926 --> 00:04:51.226 align:middle That will make a huge difference. 00:04:51.226 --> 00:04:55.666 align:middle And if you ever have any questions, we watch the comment section below each video closely 00:04:55.666 --> 00:04:56.936 align:middle and answer everything. 00:04:57.556 --> 00:04:59.036 align:middle Also keep going! 00:04:59.356 --> 00:05:03.566 align:middle In the next tutorial, we're going to become even more dangerous by diving deeper 00:05:03.566 --> 00:05:05.756 align:middle into Symfony's configuration and services: 00:05:06.226 --> 00:05:09.016 align:middle the systems that drive everything you'll do in Symfony. 00:05:09.516 --> 00:05:11.036 align:middle Alright, friends, see you next time!
