Mastering Doctrine Relations in Symfony 4!

In the part 1 of the Doctrine Tutorial we created a freakin' awesome setup: with Doctrine: entities, queries, migrations and fixtures. But, we're missing a big, giant, huge, important piece! Database relations! And once you've mastered these, you'll be unstoppable! But... a lot of information out there make Doctrine relations look over-complicated. And actually, they're simple and beautiful, especially with some recent changes in Symfony 4: Generating a ManyToOne relationship (association) The annotations for a relation The OneToMany inverse side of a relation Referencing objects across fixture classes The owning versus inverse sides of a relation Doing magic with the ArrayCollection (Criteria) Querying with Joins ManyToMany Relations Pagination! Help us bring "The Space Bar" app to the galaxy, with, (inter) stellar database relations. Yep, that's the level of humor you can expect!
