Virtual field in Ash attribute
What's the Ash way to handle virtual fields often used for inputs that are not persisted?

Generally, you will want to use
arguments on the action itself.Ash HQ

So in this password string -> hash password example, how is the password included in the changeset as an attribute to show on a form?
The changeset will include both attributes (controlled by
accept [:attr, ...], defaulting to all public, writeable attributes) and arguments. You will want to use AshPhoenix.Form to mange it, as Ash changesets are different than Ecto changesets. https://ash-hq.org/docs/module/ash_phoenix/latest/ashphoenix-formOkay. so both password and hashed password are attributes with no distinction of virtual : true or false. Got it. Thank you!!
For
Ash, attributes are persisted in the data layer, whereas arguments are ephemeral, only existing in the changeset.Okay. I will read the doc more about arguments. thanks.
