Custom / virtual fields on read
You can also try to add primary? true to your read action? And it's likely you're referencing a module that does not exist, take a look at these discussions: https://discord.com/channels/711271361523351632/799097774523547669/861263803056652288 and https://discord.com/channels/711271361523351632/799097774523547669/823438146804252702

So I have never used AshGraphql before, but perhaps you can share your code I see how you are defining the GraphQL api in your resource? At least that will provide more context.

Do you want to have a virtual field in your resource whose value is based on the existing field/attribute? If that's the case the you can use Ash Calculations: https://ash-hq.org/docs/guides/ash/latest/topics/calculations. For example if you have a User resource like the following: 
defmodule MyApp.Accounts.User do
  ...
  attributes do
    attribute :first_name, :string
    attribute :last_name, :string
  end
  ...
end
defmodule MyApp.Accounts.User do
  ...
  attributes do
    attribute :first_name, :string
    attribute :last_name, :string
  end
  ...
end
you can add a full_name calculation(virtual field) to your resource by declaring a calculation : 
calculations do
  calculate :full_name, :string, expr(first_name <> " " <> last_name)
end
calculations do
  calculate :full_name, :string, expr(first_name <> " " <> last_name)
end
that way you can now use user.full_name even if its not defined in your resource attributes. I think you can use the calculation in Ash.Query as well. If that's not what you're looking for you can share some code to provide additional context.

Implementating auto-incrementing/sequence fields in Ash Resources
Thanks for your feedback. I will also do some research regarding database triggers. For the sake of making progress 😄, will try to implement what I mentioned previously then do proper implementation later.

This is the code in handle event and on line 87 in my FormComponent: 
def handle_event("save", %{"todo" => todo_params}, socket) do
    save_todo(socket, socket.assigns.action, todo_params)
  end
def handle_event("save", %{"todo" => todo_params}, socket) do
    save_todo(socket, socket.assigns.action, todo_params)
  end
defp save_todo(socket, :new, todo_params) do
    IO.inspect(socket.assigns.form, label: "FORM")
    case AshPhoenix.Form.submit(socket.assigns.form, params: todo_params) do
      {:ok, todo} ->
        notify_parent({:saved, todo})
      ......
end
defp save_todo(socket, :new, todo_params) do
    IO.inspect(socket.assigns.form, label: "FORM")
    case AshPhoenix.Form.submit(socket.assigns.form, params: todo_params) do
      {:ok, todo} ->
        notify_parent({:saved, todo})

@Zach Daniel I managed to implement that and it worked. However I have an issue, the current user is missing in the liveview socket I have set the on_mount: callback like this: 
defmodule MyAppWeb.LiveUserAuth do
  def on_mount(:live_user_required, _params, %{"tenant" => tenant} = _session, socket) do
    Ash.set_tenant(tenant)
    IO.inspect(socket, label: "socket")

    if socket.assigns[:current_user] do
      {:cont, socket}
    else
      {:halt, Phoenix.LiveView.redirect(socket, to: "/sign-in")}
    end
  end
end
defmodule MyAppWeb.LiveUserAuth do
  def on_mount(:live_user_required, _params, %{"tenant" => tenant} = _session, socket) do
    Ash.set_tenant(tenant)
    IO.inspect(socket, label: "socket")

    if socket.assigns[:current_user] do
      {:cont, socket}
    else
      {:halt, Phoenix.LiveView.redirect(socket, to: "/sign-in")}
    end
  end
end
And in the router.ex 
scope "/", MyAppWeb do
    pipe_through :browser

    ash_authentication_live_session :ash_authentication,
      on_mount: {MyAppWeb.LiveUserAuth, :live_user_required} do
      live "/", DashboardLive.Index, :index
      ...
    end
end
scope "/", MyAppWeb do
    pipe_through :browser

    ash_authentication_live_session :ash_authentication,
      on_mount: {MyAppWeb.LiveUserAuth, :live_user_required} do
      live "/", DashboardLive.Index, :index
      ...
    end
end
* note that am setting the tenant, as the user is not on the public schema So whats happening is that when the liveview mounts(first time when socket not connected), the socket has a current_user, cause the tenant is the Process, however when the liveview is mounted again(when socket is connected), the socket does not have a current_user assigned, probably because the liveview is now in a new PID, where tenant is not set, resulting the user query running on the public_schema instead of a tenant schema. Is there a way I can resolve this?

I think in App.Api.Variant you have to define a belongs_to as supposed to adding attribute :item_id, :uuid, so something like: 
relationships do
    belongs_to :item, App.Api.Item
end
relationships do
    belongs_to :item, App.Api.Item
end

So what can an implementation in register_your_user_here(..., tenant: org.schema_name) look like? Is it right to do it this way: 
attrs = %{email: "[email protected]", password: "password12345", password_confirmation: "password12345"}

User 
|> Ash.Changeset.for_create(:register_with_password, attrs) 
|> Accounts.create()
attrs = %{email: "[email protected]", password: "password12345", password_confirmation: "password12345"}

User 
|> Ash.Changeset.for_create(:register_with_password, attrs) 
|> Accounts.create()
although the above code is raising an error:
