嵌套属性不适用于Simple_form、Decent_exposure、Strong_parameters

Question

我正在使用Simple_form与Decent_exposure，Strong_parameters我有以下设置，我可以发布到家庭，但没有发布到邻居

模型

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

has_many :neighbors
 accepts_nested_attributes_for :neighbors

视图

= 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

根据我的日志中的以下内容，表单看起来可以工作，但它没有保存到邻居嵌套模型-我已经尝试了simple_fields_for :neighbor do和simple_fields_for : neighbor，Neighbor.new do希望创建一个新的邻居会有所帮助，但它没有帮助。

确保在允许的参数中包含neighbors_attributes。
