3 models - User, Images, Interests. Everything looks ok but nothing
gets inserted into child models:(

Model code excerpt


User model =>
has_many :interests, :as => :interestible, :dependent => :destroy
accepts_nested_attributes_for :interests, :reject_if => proc {|
attributes| attributes[“name”].blank?}

accepts_nested_attributes_for :images, :reject_if => proc {|

attributes| attributes[“image_file_name”].blank?}

Controller Code


def new
@user = User.new
