https://www.youtube.com/watch?v=oxaqpDlI-Hk The first video of a series called Ash Primers has been released. Still a work in progress on recording/editing, but I'd rather ship something that isn't perfect than ship nothing at all 😆.

Issues with sorting on `first` aggregate

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

  read :published do
    prepare fn query, _context ->
      query
      |> Ash.Query.filter(air_dates.status == :published)
      |> Ash.Query.sort(latest_air_date: :desc)
      |> Ash.Query.limit(10)
    end

    # pagination do
    #   offset? true
    #   default_limit 10
    #   countable :by_default
    # end
  end
end
...
preparations do
  prepare fn query, _context ->
    query
    |> Ash.Query.load([:thumb_url, :video_file_url, :video_poster_url])
  end
end

aggregates do
  first :latest_air_date, :air_dates, :start do
    sort start: :desc
  end
end

Custom Statements

Hi I have a question How do I do the following

execute "CREATE EXTENSION IF NOT EXISTS btree_gist;"

execute """
  ALTER TABLE appointments
  ADD CONSTRAINT overlapping_appointments
  EXCLUDE USING GIST (
    doctor_id WITH =, 
    tsrange("from", "until", '[)') WITH &&
  ) WHERE (NOT canceled);
  """
end

execute "CREATE EXTENSION IF NOT EXISTS btree_gist;"

execute """
  ALTER TABLE appointments
  ADD CONSTRAINT overlapping_appointments
  EXCLUDE USING GIST (
    doctor_id WITH =, 
    tsrange("from", "until", '[)') WITH &&
  ) WHERE (NOT canceled);
  """
end

I tried to check the custom statements , it seems I am missing some import perhaps Ash.DataLayer.Info This message was copied from the ash-hq channel by user @sriky27

Coinbits V2

From @chef : We just released Coinbits 2.0 yesterday. It's been a long 6 months of building and I'm proud to announce that we're fully built on Ash, AshPostgres, and AshGraphql. No live view here, still on legacy React 😉 Reposting from the archived channel. Original message link: https://discord.com/channels/711271361523351632/1012029207343288422/1044616660377681960
