In this post I am doing an introduction on how to create migrations and how to insert data that has associations with ecto. It is a very detailed post about ecto migrations and changesets. https://thiagoramos.me/articles/how-to-use-migrations-and-insert-data-with-associations-ecto

In the second post in my series on Elixir macros, I introduce the concept of a “quoted expression”, and show how to create them using quote and unquote.

SmartLogic’s PM Alicia Brindisi & VP of Delivery Bri LaVorgna join Elixir Wizards Sundi & Owen for “Discovery Discoveries.” It’s more than a phase—it’s the art of crafting tailored solutions, perfecting client-team synergy, and meticulous documentation.

Does discovery ever really end?

The main idea of SeedFactory is to generate data in tests according to your application business logic (read as context functions if you use Phoenix Contexts) whenever it is possible and avoid direct inserts to the database (as opposed to ex_machina). This approach allows you to minimize testing of invalid states, as you’re not forced to keep complex database structure in your head in order to prepare test data.

Love Elixir’s with clause… but it can lead to confusing else statements 😕

In Elixir’s docs, it’s called the “Complex else clauses in with” anti-pattern! ❌

Thankfully, it’s easy to improve that with some refactoring! 🥳 👇

Episode 195 of Thinking Elixir. In this compelling episode, we sit down with Ben Reinhart who shares his journey of transitioning from the JavaScript ecosystem, specifically migrating off of Next.js and Vercel, to Elixir and Phoenix, with Fly.io as the new host. Ben discusses his frustrations with the complexity and performance issues he faced, and how the switch to Elixir helped streamline operations and improve the efficiency of his AI-focused product at Axflow. He delves into his strategic choice for leveraging the operational simplicity and real-time features of Phoenix, while also acknowledging trade-offs such as rebuilding front-end components. Join us to explore Ben’s story, learn about the features of Elixir that helped him, and discover how the move has influenced Axflow’s path towards finding product-market fit, and more!

I wanted to give beginners an alternate path on getting started with LiveView that didn’t need a lot of setup.

1. Copy and paste file.exs
2. $ elixir file.exs

Done!

When rendering a collection in LiveView using streams, we commonly want to display a special empty state when the collection is empty. It’s tricky to do this with Elixir constructs like if/else, but fortunately there’s a neat trick we can use to get the desired behavior using Tailwind CSS.

Cluster the Elixir app running on your laptop to an Elixir app running on Fly.io! Can be the same or different app. Step-by-step guide created and a script to help automate the process. Works great for:

• offloading AI/ML tasks to a machine with a GPU and develop our applications locally as normal
• develop and debug truly globally distributed applications right from your laptop
• And, it’s freaking cool!

This new version of the Bun installer uses Bun as a process wrapper that kills the process when the stdin closes. We now use Bun to wrap Bun itself, which allows us to remove the POSIX shell dependency on development.

You are welcome to take a look at the GitHub repo and the Hex.pm package for detailed release notes and more information.

Episode 194 of Thinking Elixir. In the final installment of our series, we sit down with the creator of the Ash framework, Zach Daniel, to move beyond his expertise in Ash and explore his experiences with the other systems we use to support our Elixir applications. Zach shares his journey from the dynamic environment of startups to the structured world of midsize companies, giving us a glimpse into the strategic timing for scaling monitoring and data collection tools. He emphasizes the value of fostering a blame-free culture and sheds light on his hands-on encounters with deployments, Kubernetes, and more!
