AshMoney with Ash.Generator

Hi, I have a resource that has an AshMoney attribute. When trying to create to with Ash.Generator I'm getting the following error

** (RuntimeError) generator/1 unimplemented for AshMoney.Types.Money
     stacktrace:

I'm tried wrapping it in a StreamData function with no change. I can't see anything in the docs about custom types with Ash.Generator. Do I need to patch AshMoney to provide the function or is there a general way to handle custom types?

You should be able to provide a custom generator or value for that particular field How are you trying to use it?

def target_price(opts \\ []) do
    changeset_generator(
      Target.Price,
      :create,
      defaults: [
        commission: Money.new(100, :USD)
        billing_amount: Money.new(200, :AUD),
        target_id: opts[:target_id]
      ],
      overrides: opts,
      authorize?: false
    )
  end

def target_price(opts \\ []) do
    changeset_generator(
      Target.Price,
      :create,
      defaults: [
        commission: Money.new(100, :USD)
        billing_amount: Money.new(200, :AUD),
        target_id: opts[:target_id]
      ],
      overrides: opts,
      authorize?: false
    )
  end

Hmmm...are there other money inputs for that action?

sansworkOP•4mo ago

there is a target resource which this is a child of which has the same two attributes.

ZachDaniel•4mo ago

Are there calls in the action to manage relationships? Or anything like that?

sansworkOP•4mo ago

yes, the target is setup with direct_control on the prices

argument :prices, {:array, :map}
change manage_relationship(:prices, type: :direct_control)

argument :prices, {:array, :map}
change manage_relationship(:prices, type: :direct_control)

ZachDaniel•4mo ago

Hmm...try setting prices to an empty list in defaults?

sansworkOP•4mo ago

That fixed it, thank you so much
