Filtering has_many relationships in Ecto
How do you filter has_many relationships based on a key from the association table?
Indented HTML syntax for Elixir
Looking for Jade or HAML for Phoenix?
Expug is a new HTML template engine. Multiline statements, correct line numbers on stack traces, Phoenix integration, and more! It’s an Elixir implementation of Pug (formerly known as Jade).
Still a few more things to go until 1.0.0, but it’s sturdy enough at 0.6.0, and improves upon existing template engines for Elixir today.
Self-referencing many-to-many relationships using Ecto
I’ve decided to do the backend for a new app I’m creating myself, using Elixir/Phoenix. I’ve been learning Elixir for the past few months and thought it would be a great opportunity to put what I’ve learned to good use.
There’s a lot of documentation about the new many_to_many macro in Ecto 2 — but somehow, it still was a bit of a pain to get this right the first time. I couldn’t find a concrete example of how a self-referencing many-to-many relationship would work with Ecto, and after some digging and the help of the awesome Elixir community, I got it working. I’m writing this post just to put this out there so you can go through this quicker.

Track changes to your Ecto model with whatwasit
Just released a package for tracking changes to your Ecto models for versioning and auditing.
The installer generates a migration file and a models/whatwasit/version.ex file to your project for easy customization.
You can check it out on hex https://hex.pm/packages/whatwasit
Using Environment Variables with Elixir and Docker
In an existing organization, Docker is a great tool to homogenize your infrastructure. Along with Exrm, I use Docker to run the same code in both the staging and production. In order to connect to different database servers, I use environmental variables to configure the server at run time.
In this blog post, I cover how to load those environmental variables in your config for both your binary and mix tasks.
Phoenix API versioning: URL
API versioning plays a big part in how an API can evolve, affecting not only technical decisions, but also product decisions. In this post, I show how simple it can be achieved with Phoenix:
