레일이 중첩 된 형태로 많은 사람들이 예상대로 작동하지 않음

나는 3 가지 모델을 가지고 있습니다.레일이 중첩 된 형태로 많은 사람들이 예상대로 작동하지 않음

이러한 모델 간의 관계는 많은 관계가 있습니다.

단위 모델

has_many :unitrentperiods, inverse_of: :unit 
    has_many :rentperiods, :through => :unitrentperiods 

accepts_nested_attributes_for :unitrentperiods

unitrentperiod 모델

belongs_to :unit 
    belongs_to :rentperiod

rentperiod 모델

has_many :unitrentperiods, inverse_of: :rentperiod 
    has_many :units, :through => :unitrentperiods

와 나는 새로운 장치를 만들거나 장치를 편집 할 수있는 단위 형태를 가지고있다. 나뿐만 아니라, 그래서 내가 내 단위 형태가 사람들을 표시 할

"6 months" 
"12 months"

추천 임대 기간을 말할 수 내 "unitrentperiod을"관리 내 단위 형태는 단지 내 장치를 관리 할 수 있지만 수 없습니다 만들고 싶어 가격 입력이 또한 기간 임대, 그래서 난 내 단위 양식을 저장할 때, 나는 또한 데이터베이스의 임대 기간에 따라 2 unitrentperiod을 저장, 난 내보기에 이런 짓을 :

처음에는 당신이 중첩 된 속성에 동의하지 않을 권리 또한 has_many :unitrentperiods

아래

accept_nested_attributes_for :unitrentperiods

를 추가, 당신은 attr_accessible을 중첩 된 속성 매개 변수를 허용하는 강력한 매개 변수를 구성해야합니다 (또는 수 on Rails 3).

여기 Gotcha : unitrentperiods_attributes을 허용해야합니다. unitrentperiods이 아닙니다.

감사합니다. 컨트롤러의 강력한 매개 변수로 모델을 업데이트하고 중첩 된 특성을 허용하여 모델을 업데이트했습니다. – NomNomNom

지금까지 올바른 것으로 보았습니다 ... 아마도'update' 액션에 문제가 있습니까? – shlajin

컨트롤러 컨트롤러와 전체 form_for를 제공하여 완벽한 컨트롤러 및 전체보기로 업데이트 – NomNomNom
