Let's finish this! Ultimately, we need to create the same $notes structure, but
with the real data. Above the foreach add a new $notes variable. Inside, add
a new entry to that and start populating it with id => $note->getId():
| ... lines 1 - 12 | |
| class GenusController extends Controller | |
| { | |
| ... lines 15 - 94 | |
| public function getNotesAction(Genus $genus) | |
| { | |
| $notes = []; | |
| foreach ($genus->getNotes() as $note) { | |
| $notes[] = [ | |
| 'id' => $note->getId(), | |
| ]; | |
| } | |
| ... lines 104 - 114 | |
| } | |
| } |
Hey! Where's my autocompletion on that method!? Check out the getNotes() method in
Genus. Ah, there's no @return - so PhpStorm has no idea what that returns. Sorry
PhpStorm - my bad. Add some PhpDoc with @return ArrayCollection|GenusNote[]:
| ... lines 1 - 11 | |
| class Genus | |
| { | |
| ... lines 14 - 105 | |
| /** | |
| * @return ArrayCollection|GenusNote[] | |
| */ | |
| public function getNotes() | |
| { | |
| return $this->notes; | |
| } | |
| } |
This will autocomplete any methods from ArrayCollection and auto-complete
from GenusNote if we loop over these results.
Now we get autocompletion for getId(). Next, add username => $note->getUsername()
and I'll paste in the other fields: avatarUri, note and createdAt. Ok, delete
that hardcoded stuff!
| ... lines 1 - 12 | |
| class GenusController extends Controller | |
| { | |
| ... lines 15 - 94 | |
| public function getNotesAction(Genus $genus) | |
| { | |
| $notes = []; | |
| foreach ($genus->getNotes() as $note) { | |
| $notes[] = [ | |
| 'id' => $note->getId(), | |
| 'username' => $note->getUsername(), | |
| 'avatarUri' => '/images/'.$note->getUserAvatarFilename(), | |
| 'note' => $note->getNote(), | |
| 'date' => $note->getCreatedAt()->format('M d, Y') | |
| ]; | |
| } | |
| $data = [ | |
| 'notes' => $notes | |
| ]; | |
| return new JsonResponse($data); | |
| } | |
| } |
Deep breath: moment of truth. Refresh! Ha! There are the 15 beautiful, random notes, courtesy of the AJAX request, Alice and Faker.
But wait - the order of the notes is weird: these should really be ordered from newest
to oldest. That's the downside of using the $genus->getNotes() shortcut: you
can't customize the query - it just happens magically in the background.
Well ok, I'm lying a little bit: you can control the order. Open up Genus
and find the $notes property. Add another annotation: @ORM\OrderBy with
{"createdAt"="DESC"}:
| ... lines 1 - 11 | |
| class Genus | |
| { | |
| ... lines 14 - 45 | |
| /** | |
| * @ORM\OneToMany(targetEntity="GenusNote", mappedBy="genus") | |
| * @ORM\OrderBy({"createdAt" = "DESC"}) | |
| */ | |
| private $notes; | |
| ... lines 51 - 113 | |
| } |
I know, the curly-braces and quotes look a little crazy here: just Google this if you can't remember the syntax. I do!
Ok, refresh! Hey! Newest ones on top, oldest ones on the bottom. So we do have some control. But if you need to go further - like only returning the GenusNotes that are less than 30 days old - you'll need to do a little bit more work.
