Questions with IngredientRef domain

[KianYang-Lee]

A domain IngredientRef is mentioned and created somewhere in chap 1 or 2. But by the end of chapter 3 (starting from Spring Data JPA) the domain of IngredientRef is already not mentioned.

What is its significance? It is quite confusing.

Exactly. The problem was created right before the 3.2 starts. In JdbcOrderRepository, he created a method saveIngredientRefs(long, List<IngredientRefs>). and called this method from saveTaco() . But while calling the method he passed tacoId and taco.getIngredients() as parameters.. But taco.getIngredients() returns a List<Ingredient> where the saveIngredientRefs() requires a List<IngredientRef>. I am also confused what to do now.

If you have found any solution please let me know.
