Ecto applied. Adding Ecto to an Elixir application without Phoenix -- Working with changesets and Phoenix forms -- Testing with sandboxes -- Creating and using custom types -- Inserting and updating with upserts -- Optimizing your application design -- Working with embedded schemas -- Creating polymorphic associations -- Optimizing IEx for Ecto -- Using schemas without tables -- Tuning for performance.;Learn how to use Ecto, the premier database library for Elixir, to connect your Elixir and Phoenix apps to databases. Co-authored by the creator of Ecto, this book provides the essentials you need to use Ecto effectively. Explore the core features--repos, queries, schemas, changesets, transactions-- gradually building your knowledge with tasks of ever-increasing complexity. Build on that core knowledge with a series of recipes featuring more advanced topics. Speed up your test suite by running database tests concurrently. Use nested associations to handle complex table relationships. Add streams to handle large result sets with ease. These recipes cover the most common situations developers run into, based on questions from Ecto users.
