嵌套屬性不Simple_form，Decent_exposure，Strong_parameters

Question

我使用Simple_form與Decent_exposure工作，Strong_parameters我有以下的設置，我可以張貼到家庭，但沒有被髮布到鄰居

模型

class Household < ActiveRecord::Base 
include ActiveModel::ForbiddenAttributesProtection 

has_many :neighbors 
accepts_nested_attributes_for :neighbors 

查看

= simple_nested_form_for household do |f| 
    = f.input :household_name 
    = f.simple_fields_for :neighbor, Neighbor.new do |neighbor_form| 
    = neighbor_form.input :first_name 
    = neighbor_form.input :middle_name 
    = neighbor_form.input :last_name 
    = neighbor_form.input :address 

    = f.button :submit 

基於以下從我的日誌它看起來像窗體工作，但它不是保存到鄰居嵌套模型 - 我已經嘗試了simple_fields_for：neighbor do和simple_fields_for：neighbor，Neighbor.new希望創建一個新的鄰居會有所幫助，但事實並非如此。

確保在允許的參數中包含neighbors_attributes。
