Ecto.Query.reverse_order
You're seeing just the function
reverse_order
, go back to Ecto.Query module for more information.
Reverses the ordering of the query.
ASC columns become DESC columns (and vice-versa). If the query
has no order_by
s, it orders by the inverse of the primary key.
Examples
query |> reverse_order() |> Repo.one()
Post |> order(asc: :id) |> reverse_order() == Post |> order(desc: :id)
