Rails 4/Devise/MongoDB:“不允许的参数"使用自定义属性和强参数 [英] Rails 4/Devise/MongoDB: "Unpermitted parameters" using custom properties and strong parameters

问题描述

尝试向我设计的 User 类添加嵌套的自定义属性 Profile(一个 Mongoid 文档).当提交设计注册表时，它应该同时创建一个用户和一个相应的个人资料对象.

Trying to add a nested custom attribute, Profile (a Mongoid document), to my devise User class. When the Devise registration form is submitted, it should create both a User and a corresponding Profile object as well.

我希望最终结果在我的 MongoDB 中看起来像这样:

I'd like the end-result to look something like this in my MongoDB:

用户:

{
  # Devise fields:
  "email": "[e-mail]",
  ...
  # Custom field
  "profile" : "<object_id>"
}

个人资料:

{
  "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，但未能创建关联的配置文件.

Unfortunately, I am receiving this in my console whenever I submit my registration. It successfully creates a User but fails to create an associated Profile.

我已经设置:

I have setup:

• Rails 4.0.0beta1、Ruby 2.0.0-p0
• 设计('rails4' 分支)，Mongoid(来自 git)
• 自定义设计注册控制器，用于添加强参数定义.

models/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

models/profile.rb:

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

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

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

controllers/users/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

routes.rb

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

我已经看过这些相关的帖子，它们似乎没有帮助:

I have already looked at these related posts, they didn't seem to help:

• Rails 4 嵌套属性未允许参数
• https://gist.github.com/kazpsp/3350730

看起来 Devise 实际上确实支持其rails4"分支中的强参数(它应该在几天内合并到 master 中.)查看代码，似乎您可以为 devise 上的每个操作覆盖一个 params 函数控制器.对于创建新用户，在我的示例中使用 sign_up_params 而不是 resource_params.

Looks like Devise does actually support strong parameters in its 'rails4' branch (which is supposed to be merged into master in a few days.) Looking through the code, it appears you can override a params function for each action on devise controllers. For creating new users, its sign_up_params instead of resource_params in my example.

尽管将此名称更改为正确的名称，但它仍然无效...仅使用此 bang 将所有参数列入白名单似乎有效:

Despite changing this name to the proper one, it still didn't work... only whitelisting all parameters using this bang seemed to work:

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

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

Obviously, this kind of defeats the purpose of strong parameters... so now the question is how do I permit my nested attributes profile_attributes (as seen in my original question)?

推荐答案

我遇到了完全相同的问题，覆盖 sign_up_params 对我有用

I had the exact same issue and overriding sign_up_params did work for me

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

当然，不同之处在于我的只是标量值，而您正在尝试批量分配关系......我想这就是您应该寻找的地方.

of course, the difference is in that mine are just scalar values, while you're trying to mass assign a relation... I guess that's where you should look for.

顺便说一下，这个主题中的文档仍然不存在(太新)，并且代码commnents建议覆盖devise_parameter_sanitizer，这是不必要的.

By the way, the documentations is still inexistint in this topic (too new), and code commnents suggest to override devise_parameter_sanitizer, which isn't necessary.
