Hi! I’m a student and this is my final project. All help would be appreciated. Essentially what I need to do is check if a Recipe object has all of the ingredients from an object of the class Pantry. However, the attributes are stored in the association Recipe_Ingredient and Pantry_Ingredient respectively. I am trying to build a Recipe App that will match recipe ingredients to those store in your “pantry”. I have the following domain model:   The recipe entity contains general information about the recipe. One thing to notice is that the Ingredients attribute is a String meaning its the paragraph of ingredients (E.g. 3 cups of rice, 2 tablespoons of salt), The ingredient entity acts as a “master” list of all ingredients (E.g. rice, salt, pepper). I have used the associations Recipe_Ingredient and Pantry_Ingredient to relate ingredients from the “master” list to object of Recipe and Pantry classes using reference selectors. Now what I have to do is implement a search function that will compare Recipe_Ingredients with Pantry_Ingredients to check if there are recipes that have the ingredients in the pantry. So, comparing two associations, I have tried a data view with the following Xpath code: [MyFirstModule.Recipe_Ingredient/MyFirstModule.Ingredient/Name = MyFirstModule.Recipe_Pantry/MyFirstModule.Pantry/MyFirstModule.Pantry_Ingredient/MyFirstModule.Ingredient/Name] It did not work probably because I have to use Recipe_Pantry to get to Pantry_Ingredient.
