我想使用選擇標籤來保存父項中的多個嵌套子項。 這是我在看 Couldn't find all UserLocations with IDs (1, 2) (found 0 results, but was looking for 2)
錯誤我有Rails 4和Devise下以下設置: 用戶 class User < ActiveRecord::Base
has_many :user_
我在創建地址的新用戶時遇到問題。我在「用戶和地址」表中創建記錄,但在用戶中尋址的外鍵仍然爲零。 class User < ActiveRecord::Base
belongs_to :address
accepts_nested_attributes_for :address
end
class Address < ActiveRecord::Base
has_
當定義在routes.rb以下路線: resources :streams
Rails的生成以下網址: streams GET /streams(.:format)
POST /streams(.:format)
new_stream GET /streams/new(.:format)
edit_stream GET /streams/:id/ed
