Category.has_many :products
Let's say a product must belong to a category. I know it is recommended to do the following:
class Product validates_presence_of :category_id end
But, as we all know, this is a pain for new records, meaning what if the associated category is a new record?
I've been meaning to ask this, but what's wrong with doing the following:
class Product validates_presence_of :category end
I never understood why that was so wrong. So I wanted to ask and see if I am missing something. What do you think? Thanks for your help!
It isn't wrong, it's the right way to do it. You just have to assign a category object when building a new Product.
