Time to try our app! First, in
.env, change the database name to
symfony3_tutorial, or whatever the database name was called when you first setup the project. Now when we run
doctrine:migrations:status... yes! We have a full database!
Let's start the built-in web server:
There are no commands defined in the "server" namespace.
Remember: with Flex, you opt in to features. Run:
composer require server
When it finishes, run:
Interesting - it started on
localhost:8001. Ah, that's because the old server is still running and hogging port 8000! And woh! It's super broken: we've removed a ton of files it was using. Hit Ctrl+C to stop the server. Ah! It's so broken it doesn't want to stop! It's taking over! Close that terminal!
Start the server again:
It still starts on port 8001, but that's fine! Go back to your browser and load
http://localhost:8001. Ha! It works! Check it out: Symfony 4.0.1.
Surf around to see if everything works: go to
/genus. Looks great! Now
/admin/genus. Ah! Looks terrible!
To use the @Security tag, you need to use the Security component and the ExpressionLanguage component.
Hmm. Let's do some digging! Open
src/AppBundle/Controller/Admin/GenusAdminController.php. Yep! Here is the
@Security annotation from FrameworkExtraBundle. The string we're passing to it is an expression, so we need to install the ExpressionLanguage.
But wait! I have a better idea. Google for SensioFrameworkExtraBundle and find its GitHub page. Click on releases: the latest is 5.1.3. What version do we have? Open
composer.json: woh! We're using version 3! Ancient!
Let's update this to
|... lines 2 - 16|
|... lines 18 - 23|
|... lines 25 - 42|
|... lines 44 - 80|
composer update sensio/framework-extra-bundle
to update just this library. Like with any major upgrade, look for a CHANGELOG to make sure there aren't any insane changes that will break your app.
So... why are we upgrading? So glad you asked: because the new version has a feature I really like! As soon as Composer finishes, go back to
GenusAdminController. Instead of using
|... lines 1 - 12|
|... line 15|
|class GenusAdminController extends Controller|
|... lines 18 - 97|
This is similar, but simpler. For the value, you only need to say:
Try it - refresh! Yes! We're sent to the login page - that's good! Sign in with password
At this point... we're done! Unless... you want to move all of your classes from
AppBundle directly into
src/. I do! And it's much easier than you might think.
