房间@Relation与复合主键

我的问题是这个问题的扩展(也是我的:)) - > 房间复合主键到外键 所以,如果我有这个类:

public class FoodWithIngredients extends Food{

    @Relation(parentColumn = "id", entityColumn = "food_id", entity = 
    Ingredient.class)
    private List mIngredients;

}

但是PrimaryKey"食物"表是composite (primaryKeys = {"id", "language_id"}).

我如何让@Relation返回记录在哪里"parentColumn = {"id", "language_id"}, entityColumn = {"food_id", food_language_id}"？
