…from the ground-up, touching on and discussing the most fundamental parts of the application. Specifically, we'll cover: Installation, Git and Setup Composer Routing Controllers Introduction to the service container Twig Doctrine Server setup Code generation Fixtures & external libraries And other tips and tricks

…Plus a ton more! Highlights: Doctrine relations, metadata, and the JoinColumn ManyToMany relationship that's bidirectional, owning versus inverse side and why that matters Loading fixtures with shared data Creating shortcuts with your very own base controller! Doctrine extensions: timestampable, sluggable Ajax: returning Json from…

…same thing. Thanks to the new bundle, we have a ton of commands that start with make! Commands for generating a security system, making a controller, generating doctrine entities to talk to the database, forms, listeners, a registration form.... lots and lots of stuff! Let…

…we need to make a little adjustment to our user repository. In src/Repository/UserRepository.php, implement another interface: UserLoaderInterface. This one comes from the Symfony Doctrine bridge, and it has a single method, so implement it down here: loadUserByIdentifier(). It takes a string $identifier …

…If one does, we get this message: "There is already an account with this email." Pretty useful. We already have this as a Doctrine constraint, but this is a validation constraint. The difference is the Doctrine constraint is enforced at the database level, so a…

…to log the user in. Here, you can customize this behavior with your own service, or use the built-in doctrine provider, which stores the token in a database table. I think the default is good enough for most cases, but it's nice to…

…error-prone: if you modify a mutable date in place, Doctrine won't see it as a change and your update will never be saved. Now generate the migration: symfony console make:migration Jump back to your editor and find that migration. Here it is…

…that no ID is set because Doctrine hasn't saved it in the database yet. I'll quickly add a PHPDoc above the variable to make PhpStorm's autocomplete happier, and delete the dd() statement: To save the new part, we need Doctrine's EntityManager…

…other two... and remove the old code: Bonus! Remove the persist() and flush() calls: Foundry handles that for us! Let's see what this does! Reload the fixtures: symfony console doctrine:fixtures:load Choose yes and... success! Back over, refresh and... it looks the same…

…file... just to make sure it doesn't contain any weird surprises. Looks good! So spin back over and run this with: symfony console doctrine:migrations:migrate Done! We now have an entity and a database table. But if you go and refresh the documentation..…

…fancy and use an Order enum for the second argument. So instead of ASC, write Order, importing the enum from Doctrine\Common\Collections, then ::Ascending->value: Super nerdy... But at least we know we didn't make a typo in those, ummm... 3 letters... Since…

…of all of the DragonTreasures we currently have, which is just this one. So in just a few minutes of work, we have a fully featured API for our Doctrine entity. That is cool. Copy the URL to the API endpoint, open a new tab…

…not related yet. Pff, try to load the fixtures anyway. Head over to your terminal and run: symfony console doctrine:fixtures:load Rutro: starship_id cannot be null on the starship_part table. Why is that column required? In StarshipPart, the starship property has a…

…SEO-friendly! Flying through space is dangerous business. Sometimes starships experience "rapid unscheduled disassemblies"... or in other words, they explode. We need a way to remove ships from our database that no longer... err... exist. Next, we'll see how to delete entities with Doctrine.

…search on and the value is the value to search for: ['slug' => $slug]: When using these out-of-the-box find methods, Doctrine automatically escapes the values, so you don't need to worry about SQL injection attacks. Adjust this if statement to if (…

…maintainability. Ok crew, that's it for this Doctrine Fundamentals course! If you're looking to upgrade your Doctrine skills, search for "Doctrine" on SymfonyCasts to find more advanced courses. The Doctrine documentation is a great resource too. And as always, if you have any…

…Open up the new migration file. I love this. Remember that migrations are generated by comparing the database to the entity class. Doctrine sees the new fields in the class, does not see the corresponding columns in the table, generates the SQL to fix that…

…cleaned up the old migrations from the last course. So this one is all about StarshipPart. Run it with: symfony console doctrine:migrations:migrate The table is in the database! But there are two fields that I like to add to all my entities: createdAt…

… Instead, pass the Starship object itself. You could pass the id if you're feeling lazy, but in the spirit of Doctrine, relationships, and thinking about objects, passing the entire Starship object is the way to go. Let's debug and see what we've…

…bundles already exist out there that are capable of this, but I wanted to approach it fresh, with a slightly different perspective. So that's what our bundle will do: translate Doctrine entities! Let's get started! Jump over to the code for this project…
