Atom fields will save upcase atoms as downcase

I noticed that if I add an attribute like this:

    attribute :currency, :atom do
      allow_nil? false

      constraints one_of: [:USD, :BRL, ...]
    end

    attribute :currency, :atom do
      allow_nil? false

      constraints one_of: [:USD, :BRL, ...]
    end

And then save a :USD or :BRL value to it, when I retrieve the record, the value will be retrieved in lower case (ex. :BRL will be returned as :brl). Is this by design? In my case I want to store the currencies supported by the Money library, but they are all in upper case, meaning that when i get them back, they are considered invalid by the Money library.

Hmm… That sounds like a bug to me

I don’t see a place in the atom type that we change the casing: https://github.com/ash-project/ash/blob/v2.10.2/lib/ash/type/atom.ex#L1

Ah, ignore it, I didn't add a unique constraint to my table, so the first row was saved with a down-case atom, and then it was creating new ones with the correct uppercase atom, but get was always fetching the first one..
