elixir - Querying by DateTime in Ecto -

here have tried.

date = ecto.datetime.from_erl(:calendar.universal_time()) query |> where([record], record.deadline >= ^date)

i tried

date = ecto.datetime.from_erl(:calendar.universal_time()) query = m in myapp.somemodel,       where: m.deadline >= ^date,       select: m

both return same message

value `%ecto.datetime{..}` in `where` cannot cast type :datetime in query

from understand supposed using ecto.datetime in queries. maybe missing obvious? thanks!

the :datetime type native type , works tuples. if set column type ecto.datetime in schema, able work higher level types ecto.datetime struct.
