I'm a beginner in Rails working through the Hartl tutorial while trying to work on my own project(s) at the same time.
One Project I'm trying to work on is a basic 'assembly' application because it's what I do now full time.
Right now it's a pretty basic app with 3 Models
Ingredient
Bulk
RecipeItem
There is a has_many through relationship between Ingredient and Bulk through RecipeItem
In the recipe_items table there is an additional attribute i'm calling quantity - it must be greater than 0 and less than 1.
The validation question I have is this.
Is there an easy way to set up a validation on a Bulk object that requires its related RecipeItem objects to add up to one...after all the recipeitem objects are added?
