Can ash_authentication Strategy.Password be modified

Hi, I know this question fits specifically into the Ash Forum category, but unfortunately, I can’t open new topics there, maybe because my account is brand new.

I was trying to wrap my head around Ash and ash_authentication and got stuck with this thing for a week. I was hoping someone could guide me in the right direction.

I have my basic ash_authentication user resource and have added attribute :trust_level, which would need to be set internally:

attributes do
	uuid_primary_key :id
	attribute :email, :ci_string, allow_nil?: false
	attribute :hashed_password, :string, allow_nil?: false, sensitive?: true
	attribute :trust_level, :integer, allow_nil?: false
end

I’m using the default setup with AshAuthentication.Strategy.Password to get the password registration working:

strategies do
  password :password do
    identity_field :email
    confirmation_required?(false)
    register_action_accept([:username, :trust_level])

    resettable do
      sender Testcourse.Accounts.User.Senders.SendPasswordResetEmail
    end
  end
end

I know I could set the :trust_level attribute by creating a new create action and using change set_attribute(:trust_level, get_trust_level), but I’m hesitant to create a new create action to create new users because AshAuthentication.Strategy.Password already provides the action register_with_password.

My question is, is it possible to add set_attribute(:trust_level, get_trust_level) to the already existent register_with_password action, or achieve a similar outcome another way? I found that there is a callback function transform in the AshAuthentication.Strategy.Password module, but I wasn’t able to understand how it works or how I could use it. I’m very new to the Elixir and Ash framework, and I’m still getting my head around the basics.

Thanks for any help.

Yes, you can do this using the global changes block, which applies a change to all actions (except :destroy actions by default)

changes do
  change SetTrustLevel, where: [action_is(:register_with_password)]
end
