before_transaction block, make the API call to get the data and set the attributes with change_attribute, or put them in a context and call set_attribute in a change block. However, when I do this, since the initial changeset doesn't have an email, it fails validation and the before_transaction never runs. If I pass in a placeholder email, I can get the before_transaction to run, but then I get warnings when calling change_attribute because the changeset has already been validated, and it's actually possible to pass in a bad email here and it'll get written to the database.Another idea I had was to try and do this as a generic action, and then in the run block I would make the API call, get the user data, and then manually call the existing
:create . However, I need to return metadata (access tokens) for the user, but it seems like generic actions don't allow for metadata blocks, and since this action will be exposed via GraphQL, I'd want that typing of the metadata attributes on the query/mutation.Basically, I want to expose an action on a user resource that accepts a token as an argument, turns that into
user_info and oauth_tokens and then can do the equivalent of the :register_with_google action in the Ash Authentication docs, returning the access token for the user as a metadata field.Note, I'll never really call this in a form, so I'm ok if the fields don't get validated until writing to the persistence layer (postgres in my case), but I do want them to be validated at some point.

I think this is what you want https://hexdocs.pm/ash/dsl-ash-resource.html#actions-create-delay_global_validations? ?
