I have 3 models, let's call them Recipe, Fruit and Nut, and I need a DRY way to set up their relationships.
Fruits and Nuts have different sets of properties Fruits and Nuts go into a Recipe A join model would be useful to track how much Fruit or Nut goes into a Recipe Different Recipes may use a Nut with the name, but different property values I might want to add a Twig or Llama model to my Recipes
Right now I have a separate join models that do pretty much the same for each of Fruit and Nut, but it's getting really wet (opposite of DRY). It works just fine, but the code is getting really redundant.
Untill I can hack rails so has_many :through works with polymorphic associations, what is a good way to do this?
class Recipe < AR::B has_many :fruitadditions has_many :fruits, :through => :fruitaddition
has_many :nutadditions has_many :nuts, :through => :nutaddition end
class Fruit < AR::B has_many :fruitadditions has_many :recipes, :through => :fruitadditions end
class Nut < AR::B has_many :nutadditions has_many :recipes, :through => :nutadditions end
TIA
