Hello there!
I have a question about polymorphic associations. Suppose we have a parent class Parent and a child class Child, to create a new object I do something like:
class Child ... :has_one :parent, :as => :resource :validates_presence_of :name ... end
class Parent ... :belongs_to :resource, :polymorphic => true ... end
child = Child.new parent = ParentClass.new parent.resource = child parent.save!
but when validation of Child fails, rails still try to execute "insert into parents (..., resourse_id) ... (..., NULL)", and because my db does not allow resource_id to be NULL, it raises a StatementInvalid exception instead of raising RecordInvalid (as it should be if the validation fails).
Am I doing something wrong or it's just a bug of rails?
Thanks.
