@namoscagnm I think for a new feature like this it would be very beneficial to add unit tests so that we can ensure regression doesn't occur down the line ...

[lucca65]

nice @namoscagnm! thanks for the contribution. Please add the unit tests and we can merge this 💪

[lucca65]

we can all meet on the support group: https://t.me/Cambiatus_Support

[lucca65]

In anyways doing unit tests isn't hard at all @namoscagnm. Elixir's documentation is, as always, incredible. Please take a look: https://hexdocs.pm/ex_unit/ExUnit.html

I'm sure doing this test is possible even without assistance, but please ping us in the group if you need anything

[lucca65]

I'll merge this and do the tests in a different PR due to inactivity. Thanks for the contribution anyway @namoscagnm

Just so you know, @namoscagnm the code you sent was not behaving correctly.

here is one of the ways to do it correctly:

  def query(Objective, _) do
    Objective
    |> order_by([c], desc: c.created_at)
  end
