Hi guys.
How do you update nested attributes for one object of a has_many :through relationship? So I have an entity model and this model can have many fact_values. The difference between fact and fact_value is that the latter has an extra value attribute. This is because facts can be common among many entities, but each entity can have its own unique value for a specific fact. So my models are the following:
class Entity has_many :fact_values has_many :facts, :through => :fact_values end
class FactValue belongs_to :entity belongs_to :fact end
class Fact has_many :fact_values has_many :entities, :through => :fact_values end
Now I've specified that Entity accepts_nested_attributes_for :fact_values. But I want it to accept nested attributes for a single (pre-defined) fact_value and update only that fact_value. The way I'm going about it right now is to have a virtual attribute in my Entity model representing that one fact_value and update that fact_value in the entity controller. I'm wondering if there is any automatic way to accomplish what I'm trying to do?
Thanks!
