Use arguments in Relationship

I would like to pass some arguments to a has_many relationship, which would be provided by a read action.

actions do
    read :list do
      argument :start_in, DateTimeUsec, allow_nil?: false
      argument :finish_id, DateTimeUsec, allow_nil?: false

      prepare build(load: :transactions)

      pagination keyset?: true, default_limit: 5, countable: :by_default
    end
  end

relationships do
    has_many :transcations, Transactions
  end

You can provide a starting query for the load load(related: Ash.Query.for_read(...)

load(transcations: Transactions.filter_dates(^start_in, ^finish_id))

defmodule Clients ....
relationships do has_many :transcations, Transactions end
actions do read :list do argument :start_in, DateTimeUsec, allow_nil?: false argument :finish_id, DateTimeUsec, allow_nil?: false prepare build(load: [transcations: Transactions.filter_dates(^start_in, ^finish_id)]) pagination keyset?: true, default_limit: 5, countable: :by_default end end end
