Two episodes down! Booya! And we are super ready to put our new skills to the test! It's finally time to make up app come alive by using Doctrine to connect to a database.

Doctrine is an amazing ORM that works great with Symfony and is super powerful. It also has a reputation for being hard to learn and for making you write a lot of code. But that's changing! Thanks to some recent improvements and Symfony Flex, working with Doctrine has never been easier or more rewarding. So, let's get started!

  • Creating (and updating) Entities with make:entity
  • Generating & using migrations
  • Inserting new data
  • Fetching & Querying for data
  • Doctrine Repositories
  • Custom queries and the query builder
  • Fixtures (Dummy data) using Faker
  • Relationships & Associations
