This is the usage:

defmodule Octafest.Blog.Post do
  use Ash.Resource,
    data_layer: AshPostgres.DataLayer

  postgres do
    table "posts"

    repo Octafest.Repo
  end

  code_interface do
    define_for Octafest.Blog
    define :create, action: :create
    define :read_all, action: :read

    define :destroy, action: :destroy
    define :get_by_id, args: [:id], action: :by_id

    read :by_id do
      argument :id, :uuid, allow_nil?: false
      get? true

      filter expr(id == ^arg(:id))

Ok so created a shared embed like so:

defmodule Octafest.Shared.Translated do
  @behaviour Access

  use Ash.Resource,
  data_layer: :embedded

  attributes do
    for locale <- ~w(en lt)a do
      attribute locale, :string
    end
  end

  @impl Access
  def fetch(term, key), do: Map.fetch(term, key)

  @impl Access
  def get_and_update(data, key, func) do
    Map.get_and_update(data, key, func)
  end

  @impl Access
  def pop(data, key), do: Map.pop(data, key)

  @impl Access
  def get(map, key, default), do: Map.get(map, key, default)

end

defmodule Octafest.Shared.Translated do
  @behaviour Access

  use Ash.Resource,
  data_layer: :embedded

  attributes do
    for locale <- ~w(en lt)a do
      attribute locale, :string
    end
  end

  @impl Access
  def fetch(term, key), do: Map.fetch(term, key)

  @impl Access
  def get_and_update(data, key, func) do
    Map.get_and_update(data, key, func)
  end

  @impl Access
  def pop(data, key), do: Map.pop(data, key)

  @impl Access
  def get(map, key, default), do: Map.get(map, key, default)

end

But the problem is still having the hardcoded locales. I mean as a workaround i can have that as a list of all available locales which for now is limited and then only show the relevant ones for the tenant?

Hmm ok back at this, i have an interesting case and trying to figure out how to best do this: Octafest is a multi-tenant thing. And translations are really tenant bound and dynamic. For e.g. Tenant A has two languages English and Lithuanian. Default is Lithuanian. Tenant B has three languages English, Italian and German. Default is english. Since json columns don't really need a defined structure the way i've done it in php land is just have json columns for the translated stuff and then show the ui according to the tenants settings. Tenant settings define what languages they support and the default language. That in turn determines what get's populated in the translated field column form. Also i've switched out the relationship, so it's not:

model 
-> translations 
  -> [
       en -> [ name: 'English name', description: 'English description ],
       lt -> [ name: 'Lithuanian name', description: 'Lithuanian description' ]       
]

model 
-> translations 
  -> [
       en -> [ name: 'English name', description: 'English description ],
       lt -> [ name: 'Lithuanian name', description: 'Lithuanian description' ]       
]

But:

model -> name -> [en: 'English name', lt: 'Lithuanian name']
      -> description -> [en: 'English description', lt: 'Lithuanian description']

model -> name -> [en: 'English name', lt: 'Lithuanian name']
      -> description -> [en: 'English description', lt: 'Lithuanian description']

Any help is greatly appreciated

It should have an empty value for each locale as i have a tabs thing where you can switch between languages. I'll have a look at the add_form thing 🙂 thank you! Ash is amazing 🙂

I can't get this to render the form though i've tried adding forms: [auto?: true] but nothing happens:

        <.simple_form for={@create_form} phx-submit="create_post">
          <.input field={@create_form[:title]} type="text" placeholder="Title..." />

          <.inputs_for :let={translations} field={@create_form[:translations]}>
            <.inputs_for :let={translation} :for={locale <- @locales} field={translations[locale]}>
              <div class="grid gap-4">
                <p class="text-sm uppercase text-gray-600"><%= locale %></p>

Yeah the whole point is to have client facing editable content for pages etc.

because this is just for adding the translated fields. I then need to modify the create changeset to include the embeds with validations add read actions which accept locale and move the fields into top level access

I'm thinking if it's worth the effort it's not that hard to do what you've shown and this adds quite a bit of magic that you can't see.
