Hello. What is the resource key in AshPhoenix.Form.for_create supposed to be for a nested key of a union type? As in: AshPhoenix.Form.for_create(ParentModule, :create, api: MyDomain.Api, forms: [ sub_field: [ type: :list, resource: ChildModule, create_action: :create,…

@kingdomcoder checking out your reproduction branch and upgrading Ash to 3.1 appears to solve the problem for me.

[image] kamaroly: It seemes to me that you are using the form before passing it to to_form() function. I’m not sure I understand what you mean

Does your action accept the options input? It is only generated for attributes that are accepted by the action.

Ah, unfortunately a significant portion of the work that’s gone into properly supporting unions has been done in branches that depend on 3.0 and wouldn’t be back ported. Any chance you could upgrade in the near future?

Ouch. I was hoping to deliver this to production and then upgrade. I guess I now have a business reason to get to that right away. Thanks, Zach!

Hey, Zach I’ve upgraded to 3.0 and I still haven’t found a workaround using the response on Discord Even with cast_tag?: true, on validation, I still get: %Ash.Error.Invalid.NoSuchInput{ calculation: nil, resource: OneOfTheUnionTypes, action: :update, input: "type", inputs: MapSet.new(…

If it would be fixed it would be fixed by cast_tag?: false not true. If that doesn’t help we may need to get a reproduction project going so I can debug properly

Can I see the resource represented by OneOfTheUnionTypes?
