What you’ll be learning
With the basic of Doctrine relations behind us, it’s time to dive deeper and get our hands dirty with some real-world, but complex collections. Honestly, this is the hardest part of Doctrine: so let’s get it right:
Creating ManyToMany associations
Querying on ManyToMany relations
Mapping the inverse (collection) side of a relation
(bonus) Using DoctrineExtension for clean URL slugs
Keeping the owning & inverse sides in-sync
Using orphanRemoval to delete items in a collection
Using cascade to save items in a collection
Counting collections in the EXTRA_LAZY way
Rendering relationship data from both sides
Filtering collections efficiently with Criteria (mind will be blown)
Dealing with complex collection forms
Adding “extra” data to the “join table”
Doctrine relationships take a little bit more work to get setup. So let’s master this stuff, setup our relationships to win, and get back to work.
