I made an Ash extension! Elixir is capable of hitting services hard; great for throughput but harsh when those services are trying to recover from an outage. The circuit breaker pattern addresses this issue and is now available in Ash! #MyElixirStatus hex.pm/packages/ash...

An example resource with a circuit breaker defined. If 10 failures are hit within 10 seconds, the action will fast fail for a minute to let the circuit reset.

LLMs don't do a great job of cleaning up after themselves. The result: developers include way too much of this AI slop in their commits. Did nobody teach them about git add --patch?

Coming soon: learn how to model payment states with ash_state_machine! The demo also includes background job processing to simulate payments, auth policies, and real time updates. All made easy with Ash! Which part are you interested in learning? #ElixirLang #AshFramework

Embedded Ecto schemas in forms and a brief intro to Multi? Coming soon in the Budgie series on Code and Stuff! #MyElixirStatus

An example of an Ecto embedded schema, containing a full budget object and an additional decimal field called `period_funding_amount`.

embedded_schema do
field :period_funding_amount, :decimal
embeds_one(:budget, Budget)
end

$An Elixir function called `construct_multi`, which inserts a budget and funds it if necessary. defp construct_multi(data) do Ecto.Multi.new() |> Ecto.Multi.insert(:budget, data.budget) |> Ecto.Multi.run(:fund_budget, fn repo, %{budget: budget} -> fund_budget_if_necessary(repo, budget, data) end) end$

Did you know @ash-hq.org can import existing database tables as resources automatically? It can even generate relationships and constraints! #AshFramework #ElixirLang
