Doctrine ORM is the de facto standard ORM in Symfony applications. In recent years Doctrine DBAL & ORM have seen new major releases and with that breaking changes and updated recommendations on their usage. In this wokshop we want to introduce you to current best practices with Doctrine ORM and DBAL, as well as a deep dive of some of the more advanced features in Doctrine. In a series of exercises in a demo application we will explore these functionalities in practice.

While this workshop does not focus on modernization/upgrading to the most recent major versions, we will discuss some of the breaking changes and how to tackle them, if this is relevant to participants. Please note, that basic familiarity with Symfony & Doctrine are assumed. If you have no prior experience with Doctrine (or similar ORMs), we will try to accommodate as best as we can.
