…that Doctrine is going to handle the heavy lifting of inserting and removing records to and from this table for us. We'll see that in a minute. But before I forget, head back to your terminal and run this migration: symfony console doctrine:migrations…

…But what if the built-in filters aren't enough? What if we need to add some custom filtering logic? Let's do that next by first creating a custom filter for a Doctrine entity and later creating a custom filter for our DailyStats resource.

…Next, let's talk about pagination. Because if we go back to /api/daily-stats.jsonld and refresh... there are a lot of items here. Since we're not using Doctrine, we no longer get pagination for free. If we need it, we have to…

…new data has been deserialized into it. The failure is from our first test case: we currently allow this item to be published, even though the description is short. Next, let's prevent this. How? It's back to our "original data" trick from Doctrine.

…they're only heavy in when you actually using them. Makes sense. Lovely. So this is cool and all. Let's move on to doctrine. Look at this five lines of code. It's a form. For yourself, think about potential issues with this code…

…Nyholm uses that all the time. So in his handlers, he just kind of writes doctrine code and there's something else that wraps that in a transaction and then commits the transaction afterwards. Um, and really the main thing, the most important thing for…

…itself. So you'll probably see new places being used for that. There are a lot of adopters right now. This is maybe not even complete, but there's APCu a PHP Array in memory chaining several using Doctrine, um, existing adopters from them. There…

…can, I can change it. What you can use, it's actually Doctrine User Provider which is included in Symfony 4 so it's simple and easy to integrate. Then you need to, only thing that you need to do is bin/console maker:user…

…method: public function getPublishedCheeseListings() that will also return a Collection. Inside, return $this->cheeseListings->filter(), which is a method on Doctrine's collection object. Pass this a callback function(){} with a single CheeseListing argument. All that function needs is return $cheeseListing->getIsPublished(). If you're…

…ids. Try this: $em = self::$container - a parent class sets the container on this nice property - ->get() and the service id. Use doctrine then say ->getManager(). You can also use the type-hint you use for autowiring as the service id. In other words…

…make:migration Move over... and double-check the SQL: CREATE TABLE user - looks good! Run it with: php bin/console doctrine:migration:migrate Perfect! We have a gorgeous new Doctrine entity... but as far as API Platform is concerned, we still only have one API…

…you TDD everything? Yes. I was really interested because I found TDD to be very wrong for Symfony, the Symfony part, like using the Forms, using the Doctrine and stuff like that. And I was wondering, okay, how do you do that? Oh, we don…

…composer require api is in fact, um, launching a Flex recipe that will install API Platform, but also the doctrine-bundle, CORS support - Cross Origin Resource Management - and everything you need to basically have an API started. So these three steps, and I'm done…

…console make:migration Let's go check out that new file. Yep! No surprises: it just makes the column not required. Move back over and run this with: php bin/console doctrine:migrations:migrate Excellent! Let's try to register! Register as geordi@theenterprise.org…

…for now. We will add a password later, but we'll keep things extra simple to start. And... we're done! Awesome! This created a User entity, a Doctrine UserRepository for it, and updated the security.yaml file. Let's check out these changes next!

…actually, a better question is: should we solve this? Here's the point: you need to be aware of the fact that Doctrine's nice relationship lazy-loading magic makes it easy to accidentally make many queries on a page. But, it is not something…

…owning versus inverse stuff is important because, when Doctrine saves an entity, it only looks at the owning side of the relationship to figure out what to save to the database. So, if we add tags to an article, Doctrine will save that correctly. But…

…make sense anymore? I mean, if we're already making a JOIN to the article table, isn't this extra query unnecessary? Doesn't Doctrine already have all the data it needs from the first query, thanks to the join? The answer is... no, or…

…places. One mistake could lead to an OR causing many more results to be returned than you expect! To best handle this in Doctrine, always use andWhere() and put all the OR logic right inside: c.content LIKE :term OR c.authorName LIKE :term. On…

…if you needed your SlackClient service, you would just add a __construct() method and autowire it! With our new knowledge, let's keep going and start mastering features, like the Doctrine ORM, form system, API stuff and a lot more. Alright guys, seeya next time…
