アーティストモデルの attr_accessible に次のものがあります
attr_accessible :media_items_attributes, :galleries_attributes, :name, :bio, :permalink, :billboard_image_id, :featured_at, :city, :state, :country, :latitude, :longitude, :visible, :confirmed_at, :published_at, :deleted_at, :genre_ids, as: :admin
しかし、私はまだ例外が発生します
Can't mass-assign protected attributes: media_items_attributes
私のギャラリーモデルには次のものがあります
attr_accessible :media_items_attributes
私は困惑しています。
どこで許可する必要があります:media_items_attributesか?
class Gallery < ActiveRecord::Base
belongs_to :galeryable
attr_accessible :media_items_attributes
has_many :media_items, :as => :mediable
accepts_nested_attributes_for :media_items
end
class Artist < ActiveRecord::Base
