I am trying to parse a user generated filter that will apply to jsonb field (that is just a map, not an embedded resource).

The field is data, and if I include it in the statement sent to parse_input I get an Ash.Error.Query.NoSuchFilterPredicate error.

If I exclude that field, and instead manually apply it, |> Ash.Query.filter(data[:size] == ^"Big") then things works.

Is there a syntax to allow passing fields of a map into the parse function? If not, how can I pass it to Ash.Query.filter? To make it slightly more complicated, I would also like to be able to filter on the data field when it is on a reference as well. e.g. `%{person: %{data: %{size: “Big”}}}

    statement = %{
      person: %{parent: %{name: "Daniels"}},
      data: %{size: "Big"}
    }

    # This will blow up with the above
    {:ok, filter} = Ash.Filter.parse_input(resource, statement)

    # If I remove "data" and instead do it manually, then this works:
    resource
    |> Ash.Query.for_read(read_action, %{}, actor: actor, tenant: tenant)
    |> Ash.Query.filter_input(filter)
    |> Ash.Query.filter(data[:size] == ^"King")

Filtering on embedded resource? - #6 by zachdaniel was where I saw the Ash.Query.filter approach on arbitrary fields of a jsonb attribute; I just couldn’t figure out how to pass my user generated filter since that is a macro.

Thank you!
