First of all, I’d like to thank you for have written this book, it’s a precious resource indeed. That said, my problem is when we have to migrate model V1 to model V2, replacing the types Meat and Fish with the type Entrée. Why it is necessary to also add the filter predicate type != ‘Fish’ && type != ‘Meat’ to the RecipeToRecipe entity mapping? Why is not sufficient the filter predicate added to the Fish And Meat em?
Thanks for your patience.
Best regards, MI
