設計nested_attributes字段顯示數據，但不更新模型

Question

我有以下代碼（Slim格式），其中顯示一個表格users。 user的數據在提交時顯示並更新。但是，phone這是來自publisher的嵌套屬性，當我加載表單時顯示當前數據，但不會在提交時更新。

查看

= form_for current_user, url: user_registration_path, html: {class: 'account'} do |user_form| 
    .row 
    .control-group.text-center 
     label.col-9 Email 
     = user_form.text_field :email, class: 'col-7' 

    = fields_for :publisher, current_user.publisher do |publisher_form| 
    .row 
     .control-group.text-center 
     label.col-9 Phone 
     = publisher_form.text_field :phone, class: 'col-7' 

註冊記憶控制器

class RegistrationsController < Devise::RegistrationsController 

    def update_resource(resource, params) 
    resource.update_without_password(params) 
    end 

end 

應用控制器

class ApplicationController < ActionController::Base 
    # Prevent CSRF attacks by raising an exception. 
    # For APIs, you may want to use :null_session instead. 
    protect_from_forgery with: :exception 

    before_action :configure_permitted_parameters, if: :devise_controller? 

    protected 

    def configure_permitted_parameters 
    devise_parameter_sanitizer.for(:account_update) {|u| u.permit(
     :first_name, 
     :last_name, 
     :email, 
     :password, 
     :password_confirmation, 
     :current_password, 
     publisher_attributes: [:phone, :payment_details], 
     banner_attributes: [:website, :banner_msg, :signup_msg, :bg_col, :txt_col, :btn_col] 
    )} 
    end 
end 

用戶模型

class User < ActiveRecord::Base 
    has_one :publisher 
    # Include default devise modules. Others available are: 
    # :confirmable, :lockable, :timeoutable and :omniauthable 
    devise :database_authenticatable, :registerable, 
     :recoverable, :rememberable, :trackable, :validatable 

    accepts_nested_attributes_for :publisher 

    validates_presence_of :first_name, :last_name 
    validates_length_of :first_name, maximum: 100 
    validates_length_of :last_name, maximum: 100 

end

我終於發現，

= fields_for :publisher, current_user.publisher do |publisher_form| 

應該是：

= user_form.fields_for :publisher, current_user.publisher do |publisher_form|
