About policies

It seems that policies are not triggered. I found this and tried but without success. https://discord.com/channels/711271361523351632/1079519120971812914

# api code
  authorization do
    authorize :by_default
  end

# organization code
  policies do
    policy always() do
      authorize_if relates_to_actor_via(:users)
    end
  end

# code interface usage
Accounts.Organization.list!()
# [debug] QUERY OK source="acl_organizations" db=3.4ms idle=1311.1ms
#SELECT a0."id", a0."subject" FROM "acl_organizations" AS a0 []

Accounts.Organization.list!(authorize?: true)
# Policy | 🔎:
#   authorize if: record.users == actor | ✘ | 🔎

Accounts.Organization.list!(actor: current_user)
# Policy | 🔎:
#   authorize if: record.users == actor | ✓ | 🔎

# NOTE: Query little bit more complex because it has many to many relationship with actor
# [debug] QUERY OK source="acl_organizations" db=6.1ms queue=0.1ms idle=1397.1ms

# api code

# organization code

From examples we can see, that policies are invoked only if i explicitly pass authorize?: true or actor: current_user even tho in api i have defined authorize :by_default

How to create organization after user creation.

Ideally it would create organization for user after registration, but if user comes from invitation (to specific organization) than it does not create new one. No functionality is created yet, im not sure, how to even approach this. In user resource there isnt even actions for create. Apparently its definition happens somewhere in i suppose.

  authentication do
    api Domain.Accounts

    strategies do
      password :password do
        identity_field :email
        sign_in_tokens_enabled? true
      end
    end

    tokens do
      enabled? true
      token_resource Domain.Accounts.Token
      signing_secret Application.compile_env(:domain, DomainWeb.Endpoint)[:secret_key_base]
    end
  end

  authentication do
    api Domain.Accounts

    strategies do
      password :password do
        identity_field :email
        sign_in_tokens_enabled? true
      end
    end

    tokens do
      enabled? true
      token_resource Domain.Accounts.Token
      signing_secret Application.compile_env(:domain, DomainWeb.Endpoint)[:secret_key_base]
    end
  end

Sorry if i ask noob questions, i find docs rather confusing.

select relationship

Resource relevant parts

relationships do
  belongs_to :debit_account, Budget.Account, allow_nil?: false
  belongs_to :credit_account, Budget.Account, allow_nil?: false
end

actions do
  defaults [:create, :read, :update, :destroy]
end

relationships do
  belongs_to :debit_account, Budget.Account, allow_nil?: false
  belongs_to :credit_account, Budget.Account, allow_nil?: false
end

actions do
  defaults [:create, :read, :update, :destroy]
end

In live view form_component i have form where i show select to select relationship

# update
assign_new(assigns, :accounts, fn _ -> Budget.Account.list!() |> Enum.map(&{&1.subject, &1.id}) end)}

# Form preperation
AshPhoenix.Form.for_create(Budget.Payment, :create, api: Budget, actor: current_user)

# render
<.input field={{f, :credit_account_id}} type="select" prompt="Select credit account" label="Credit account" options={@accounts} />
<.input field={{f, :debit_account_id}} type="select" prompt="Select debit account" label="Debit account" options={@accounts} />

# update
assign_new(assigns, :accounts, fn _ -> Budget.Account.list!() |> Enum.map(&{&1.subject, &1.id}) end)}

# Form preperation
AshPhoenix.Form.for_create(Budget.Payment, :create, api: Budget, actor: current_user)

# render
<.input field={{f, :credit_account_id}} type="select" prompt="Select credit account" label="Credit account" options={@accounts} />
<.input field={{f, :debit_account_id}} type="select" prompt="Select debit account" label="Debit account" options={@accounts} />

Input component

# Input preperation
def input(%{field: {f, field}} = assigns) do
  assigns
  |> assign(field: nil)
  |> assign_new(:name, fn ->
    name = Phoenix.HTML.Form.input_name(f, field)
    if assigns.multiple, do: name <> "[]", else: name
  end)
  |> assign_new(:id, fn -> Phoenix.HTML.Form.input_id(f, field) end)
  |> assign(:value, AshPhoenix.Form.value(f, field))
  |> assign(:errors, AshPhoenix.Form.errors(f, format: :simple, for_path: [])[field] |> List.wrap)
  |> input()
end

# Input preperation
def input(%{field: {f, field}} = assigns) do
  assigns
  |> assign(field: nil)
  |> assign_new(:name, fn ->
    name = Phoenix.HTML.Form.input_name(f, field)
    if assigns.multiple, do: name <> "[]", else: name
  end)
  |> assign_new(:id, fn -> Phoenix.HTML.Form.input_id(f, field) end)
  |> assign(:value, AshPhoenix.Form.value(f, field))
  |> assign(:errors, AshPhoenix.Form.errors(f, format: :simple, for_path: [])[field] |> List.wrap)
  |> input()
end

I dont understand why but selects does not hold their selected value. I can select one, but once i select other first looses value. For plain string value AshPhoenix.Form.value(f, field) returns correct input value, but for selects not. Unrelated: for errors i had to do: AshPhoenix.Form.errors(f, format: :simple, for_path: [])[field], because AshPhoenix.Form.errors(f, format: :simple) returned %{[] => %{key => value}} If some relevant info is missing please let me know, i will provide it.

Union relationships

Hello i have 2 resources. Accounts and Payments. Each payment has 2 relationships to accounts

relationships do
  belongs_to :debit_account, Budget.Account
  belongs_to :credit_account, Budget.Account
end

relationships do
  belongs_to :debit_account, Budget.Account
  belongs_to :credit_account, Budget.Account
end

And i want to have one relationship in Account

relationships do
  has_many :payments, Budget.Payment
end

relationships do
  has_many :payments, Budget.Payment
end

Is there a way how i could have payments relationship to hold both those so i could have one list with all payments to order/paginate/filter on it.

All extensions list.

In one of the talks i heard cqrs/commanded mentioned. Is there some package at least in beta or smth? And broader question is where are list of all extensions, even 3rd party? I understand that ash currently is pretty young and theres probably not much, but i see huge potential in reusability and having something like https://tailwindcomponents.com/ but for ash resources.
