是否有任何可能的方式使用nested_attributes_for在下面顯示的方式? 基本上我想創建一個人,一個或多個汽車,併爲每輛車添加細節。這只是一個模擬,不是一個非常現實的例子。因爲它尚未創建,所以在試圖構建汽車的細節時會受到阻礙。accepted_nested_attributes_for - belongs_to,has_many,fields_for
型號:
class Person < ActiveRecord::Base
has_many :cars
accepts_nested_attributes_for :car
end
class Car < ActiveRecord::Base
belongs_to :person
has_many :details
accepts_nested_attributes_for :details
end
class Detail < ActiveRecord::Base
belongs_to :car
end
形式:
form_for @person do |f|
#fields
f.fields_for :car do |car|
#fields
car.fields_for :details |detail|
=detail.text_field :content
end
end
end
