manage_relationship does not insert

    create :register do
      accept [:name]
      argument :members, {:array, :map}, public?: false, default: []

      change manage_relationship(:members, type: :create, on_match: :ignore, on_no_match: :create) do
        [%{
          user_id: actor(:id),
          role: "owner",
          entity_id: ref(:id)
        }]
      end

      load :members
    end

    create :register do
      accept [:name]
      argument :members, {:array, :map}, public?: false, default: []

      change manage_relationship(:members, type: :create, on_match: :ignore, on_no_match: :create) do
        [%{
          user_id: actor(:id),
          role: "owner",
          entity_id: ref(:id)
        }]
      end

      load :members
    end

I just tried to create a :register action for Entity to create Member with actor as owner, but it only inserts in entities table

That syntax is incorrect Not sure where the do block w/ input came from (I suspect an LLM?) When you want to provide input like that, (i.e not map an argument value directly to a manage_relationship) then you have to do it in a custom change

 create :register do
    accept [:name]
    change fn changeset, context ->
      Ash.Changeset.manage_relationship(changeset, :members, [...input], type: :create)
    end

    load :members
  end

 create :register do
    accept [:name]
    change fn changeset, context ->
      Ash.Changeset.manage_relationship(changeset, :members, [...input], type: :create)
    end

    load :members
  end

Please see the #rules

AI generated code must also be marked as such, especially when requesting support or help related to it.

(no worries, its a new rule)

Sorry about that. It worked, still cannot get the actor in there :))))

context.actor

Somehow passing for_create(:register, actor: user) does not work in tests And when I add the relationship to Entity, the entity_id does not get added, and it is not present in the changeset, Should I manually create it in after_change? Or is there a way to specify that after creating Entity, the id should be put in relationships

ZachDaniel•5mo ago

You don't need to add the entity_id manage_relationship handles that It handles the source_attribute at least, if that is what entity_id is

  actions do
    defaults [:read, :destroy, update: :*]

    create :register do
      accept [:name]

      argument :members, {:array, :map}, default: []

      change fn changeset, context ->
        IO.inspect(context, label: "Context in change")

        changeset =
          Ash.Changeset.manage_relationship(
            changeset,
            :members,
            %{user_id: context.actor.id, role: "owner"},
            type: :create
          )

        IO.inspect(changeset, label: "BAfter manage relationship")
      end
    end
  end

        IO.inspect(changeset, label: "BAfter manage relationship")
      end
    end

That looks right to me

VahagnOP•5mo ago

I have made something like this, can't get LLM to write me a simple manage_relationshiop

ZachDaniel•5mo ago

What does the relationship look like? is entity_id the source_attribute?

VahagnOP•5mo ago

  relationships do
    belongs_to :user, Aldente.Accounts.User
    belongs_to :entity, Aldente.Management.Entity
  end

  relationships do
    belongs_to :user, Aldente.Accounts.User
    belongs_to :entity, Aldente.Management.Entity
  end

ZachDaniel•5mo ago

What does the primary create action look like on member?

VahagnOP•5mo ago

    create :create do
      primary? true
      accept [:role, :user_id, :entity_id]
      argument :role, :string, allow_nil?: false
      argument :user_id, :uuid, allow_nil?: false
      argument :entity_id, :uuid, allow_nil?: false
    end

    create :create do
      primary? true
      accept [:role, :user_id, :entity_id]
      argument :role, :string, allow_nil?: false
      argument :user_id, :uuid, allow_nil?: false
      argument :entity_id, :uuid, allow_nil?: false
    end

This is also LLM code adding all the arguments Isn't accept enough? Just removed argument rows and it worked fine

ZachDaniel•5mo ago

Yeah those arguments shouldn't be there 😄 Just the accept
