Rails 4.2.4 / 设计 - 如何允许嵌套属性

Question

我在尝试使用 Devise 清除嵌套表单的某些参数时遇到了一些问题。这是我的代码，最后解释了我已经尝试过的内容。

我在 SO 中找到了一堆答案，但所有答案似乎都指向只放 :address_attributes => [:etc]，但它对我不起作用。

用户模型

class User < ActiveRecord::Base

  has_many :addresses, dependent: :destroy
  has_many :phones, dependent: :destroy

  accepts_nested_attributes_for :addresses, allow_destroy: true
  accepts_nested_attributes_for :phones, allow_destroy: true

end

地址

class Address < ActiveRecord::Base
  belongs_to :user
end

电话

class Phone < ActiveRecord::Base
  belongs_to :user
end

形式

  .row
    .col-md-3
      %p 2. Complete seus dados pessoais
    .col-md-9
      = simple_form_for @user, url: user_registration_path, method: :patch, class: 'form-inline' do |f|
        = f.input :name, label: 'Nome Completo'
        = f.input :birth_date, label: 'Data de Nascimento', start_year: 1910
        = f.input :cpf, label: 'CPF'
        .row
          = f.simple_fields_for @user_phone do |ff|
            .col-md-4
              = ff.input :country_code, label: 'Código do País'
            .col-md-4
              = ff.input :area_code, label: 'DDD'
            .col-md-4
              = ff.input :number, label: 'Telefone'

        = f.simple_fields_for @user_address do |ff|
          = ff.input :zip_code, label: 'CEP'
          = ff.input :street, label: 'Rua'
          = ff.input :street_number, label: 'Número'
          = ff.input :district, label: 'Bairro'
          = ff.input :complement, label: 'Complemento'
          = ff.input :state_id, collection: @states, label: 'Estado'
          = ff.input :city_id, collection: @cities, label: 'Cidade'
        = f.submit 'Salvar'

设计注册控制器

class Users::RegistrationsController < Devise::RegistrationsController
    before_filter :configure_sign_up_params, only: [:create]
    before_filter :configure_account_update_params, only: [:update]

  def configure_account_update_params
    devise_parameter_sanitizer.for(:account_update) do |u| 
      # raise
      u.permit(:username, :name, :birth_date, :cpf, :phone_attributes =>    [:country_code, :area_code, :number], :address_attributes => [:zip_code, :street_number, :street, :district, :complement, :state_id, :city_id])
    end
  end

结束

如果它尝试放置 :address_attributes => [:etc]，我会得到未经许可的参数。如果我只尝试：address => [:etc]，我会得到“找不到用户的属性地址”。

我试过输入复数 (:addresses_attributes) 但它不起作用。

设计控制器已经在路由中配置，并允许我编辑模型本身的所有字段，问题仅在嵌套模型中。

谁能帮忙？

Answer 1

您遇到的主要问题是您的 fields_for 未正确初始化您的嵌套属性 - 参数应分别通过 phones_attributes 和 addresses_attributes。

因此，您最好使用以下方法：

#config/routes.rb
devise_for :users, controller: { registrations: "registrations" }

#app/controllers/registrations_controller.rb
class RegistrationsController < ApplicationController
   def new
     build_resource({})
     self.resource.phones.build
     self.resource.addresses.build
     respond_with self.resource
   end
end

那么在你看来：

#app/views/registrations/new.haml
...
= f.simple_fields_for :phones do |ff|
   ...
= f.simple_fields_for :addresses do |ff|
   ...

这应该设置正确的属性以通过您的模型传递。
