ruby-on-rails – Rails 4 / Devise / MongoDB：使用自定义属性

尝试将嵌套的自定义属性Profile(一个Mongoid文档)添加到我的设计用户类.提交Devise注册表单时,它还应创建用户和相应的Profile对象.

我希望最终结果在我的MongoDB中看起来像这样：

用户：

{
  # Devise fields:
  "email": "my@email.com",...
  # Custom field
  "profile" : "<object_id>"
}

轮廓：

{
  "first_name": "Dave",....
}

不幸的是,每当我提交注册时,我都会在控制台中收到此消息.它成功创建了一个用户,但无法创建关联的配置文件.

我有设置：

>自定义Devise注册控制器,用于添加强参数的定义.

车型/ user.rb：

class User
  include Mongoid::Document

  devise :database_authenticatable,:registerable,:recoverable,:rememberable,:trackable,:validatable,:token_authenticatable,:confirmable,:lockable,:timeoutable

  field :email,type: String,default: ''

  ...

  has_one :profile
  accepts_nested_attributes_for :profile
end

车型/ profile.rb：

class Profile
  include Mongoid::Document
  include Mongoid::Timestamps

  # Attributes
  # ----------
  field :slug,default: '' # Acts as user-'friendlier' slug
  field :birthday,type: DateTime,default: DateTime.now
  field :first_name,default: ''
  field :occupation_title,default: ''

  belongs_to :user
  embeds_many :photos
  has_one :occupation_industry,:as => :industry
end

控制器/用户/ registrations_controller.rb

class Users::RegistrationsController < Devise::RegistrationsController

  def resource_params
    params.require(:user).permit(:email,:password,:password_confirmation,:profile_attributes)
  end
  private :resource_params
end

的routes.rb

devise_for  :users,:path => '',:path_names => {
                :sign_in => 'login',:sign_out => 'logout',:sign_up => 'register'
                },:controllers => {
                :registrations => "users/registrations",:passwords => "users/passwords"
              }

我已经查看了这些相关帖子,他们似乎没有帮助：

编辑：

看起来Devise确实支持其“rails4”分支中的强参数(它应该在几天内合并到master中.)查看代码,看起来你可以为设计控制器上的每个动作覆盖params函数.对于创建新用户,在我的示例中使用sign_up_params而不是resource_params.

尽管将此名称更改为正确的名称仍然无法正常工作…只使用此爆炸将所有参数列入白名单似乎有效：

def sign_up_params
  params.require(:user).permit!
end

显然,这种方法违背了强参数的目的……所以现在的问题是如何允许我的嵌套属性profile_attributes(如我原来的问题所示)？

def sign_up_params
   params.require(:user).permit(:email,:other,:etc)
end
