Also can use Enum.map_join/3 like:
def build_string(a, b, ops, sep) do
Enum.map_join(ops, sep, &calculate(a, b, &1))
end

I wrote a blog post about how we have been using Ecto Queries for search / filter forms in web applications. It aims at the same problem as the ransack gem in the rails world, but with less magic.

Thanks for sharing! Great post and I love the accompanying Livebook as a means of extending the content without adding too much bloat to the post itself. That’s a great pattern for future content like that.

I took a deep-dive into Upserts with Ecto and investigated odd behaviors like:
- Why does Ecto return a new
binary_idevery time I upsert a schema? - Why do upserts introduce gaps in the
