elixir - Timex - using datetime with a migration -


i've got following module :

defmodule soundbuttonsapi.accounts.session   use ecto.schema   use timex   import ecto.changeset    schema "accounts_sessions"     field :expires_at, timex.ecto.datetime, null: false     field :token, :string, null: false     field :user_id, :id, null: false      timestamps()   end    def changeset(model, params \\ :empty)     model     |> cast(params, [:user_id])     |> set_token()     |> set_expires_at()     |> validate_required([:user_id, :token, :expires_at])   end    defp set_token(changeset)     put_change(changeset, :token, uuid.uuid4())   end    defp set_expires_at(changeset)     put_change(changeset, :expires_at, timex.shift(timex.now(), days: 1))   end end

and associated migration :

defmodule soundbuttonsapi.repo.migrations.createsoundbuttonsapi.accounts.session   use ecto.migration    def change     create table(:accounts_sessions)       add :token, :string       add :expires_at, :utc_datetime       add :user_id, references(:accounts_users, on_delete: :nothing)        timestamps()     end      create index(:accounts_sessions, [:user_id])     create index(:accounts_sessions, [:token])   end end

but insertion attempt yield following error : (caseclauseerror) no case clause matching: {{{2017, 4, 8}, {10, 8, 58, 947735}}}

any idea how fix ?

i using versions 3.1 of both timex , timex_ecto.

edit : full stacktrace of error :

edit 2 : culprit (?) code :

def create(conn, %{"user" => user_params})     user = repo.get_by!(soundbuttonsapi.accounts.user, email: user_params["email"])     {:ok, %session{} = session} <- accounts.create_session(%{user_id: user.id}) # line 26       conn       |> put_status(:created)       |> put_resp_header("location", session_path(conn, :show, session))       |> render("show.json", session: session)     end   end

and create_session :

  def create_session(attrs \\ %{})     %session{}     |> session.changeset(attrs)     |> repo.insert()   end
