Mnesia qlc queries with filters error (:undefined_record)

Using Mnesia recently, I am trying to move from match_spec to qlc queries in order to query multiple tables at once. I am facing an error trying to apply qualifiers for filtering my results :

require Qlc

defmodule TestSchema do
  defstruct id: nil, field: nil
end

:mnesia.start()

:mnesia.create_table(:test, [
  ram_copies: [node()],
  record_name: TestSchema,
  attributes: [:id, :field],
  type: :ordered_set
])

Qlc.q("[A || A <- mnesia:table('test'), A#'TestSchema'.field == \"field 2\"]", [])

# => ** (MatchError) no match of right hand side value: {:not_ok, [error: {1, :erl_lint, {:undefined_record, :TestSchema}}]}
#  (qlc) lib/qlc.ex:183: Qlc.expr_to_handle/3

Is the syntax right ?

I a possible solution may be to declare Erlang record, Record.defrecord/2 only provide utilities to manipulate such type.

any clues ?
