Ruby Rails 4设备3.2使用自定义属性注册，未知属性错误

这个问题看起来很简单，让我抓狂，到目前为止已经花费了我数周的生产时间，我看这个问题不会很快消失，因为它会在嵌套属性出现的任何地方出现

Started POST "/users" for 127.0.0.1 at 2013-11-12 04:56:03 +0100
Processing by Devise::RegistrationsController#create as HTML
  Parameters: {"utf8"=>"✓", "authenticity_token"=>"afucNMlRRQkgBeKVVwOQxvjtMtvCDPiQLilr7TXXnUg=", "user"=>{"email"=>"test7@test.com", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]", "first_name"=>"test7", "last_name"=>"test7", "preferred_language"=>"en", **"master_data_contact_information"=>**{"contact_email"=>"test7@test.com", "primary_phone_number"=>"23452352345234", "secondary_phone_number"=>"324523453245", "fax_number"=>"23452345234"}, "group_token"=>""}, "commit"=>"Register"}
Completed 500 Internal Server Error in 96ms

ActiveRecord::UnknownAttributeError (unknown attribute: master_data_contact_information):

怎么会不知道呢？就在那里

def configure_permitted_parameters
  devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:email) }
  devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:email, :password,
  :password_confirmation, :first_name,
  :last_name, :preferred_language,
  :group_token,
  :master_data_contact_information =>
    [:contact_email, :primary_phone_number, :secondary_phone_number, :fax_number ]
 ) }
end

---

如果我将其更改为：

def configure_permitted_parameters
  devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:email) }
  devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:email, :password,
  :password_confirmation, :first_name,
  :last_name, :preferred_language,
  :group_token
  ) }
end

我明白了

那么，如何处理嵌套资源和强参数呢

在RubyMine控制台中运行时，它工作正常

params = ActionController::Parameters.new user: {"email"=>"test5@test.com", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]",
                                                 "first_name"=>"testqr", "last_name"=>"nsdfjkhasdfjk", "preferred_language"=>"en", "group_token"=>"",
                                                 "master_data_contact_information"=>
                                                     {"contact_email"=>"test10@test.com", "primary_phone_number"=>"786789678678",
                                                      "secondary_phone_number"=>"56675675876567", "fax_number"=>"2456246"}}



p = params.require(:user).permit(:email, :password, :password_confirmation, :first_name,
                                 :last_name, :preferred_language, :group_token,
                                 :master_data_contact_information => [:contact_email, :primary_phone_number, :secondary_phone_number, :fax_number ]
)

一切都是闪亮的

我知道Rails核心人员希望使Rails更加安全，但这占用了我很多时间

是的，它在简单的模型上非常有效

当事情开始变得有点复杂时，一切都会失去。

尝试将

:master\u data\u contact\u information

更改为

：master\u data\u contact\u information\u attributes

所以你有这样的东西：

def configure_permitted_parameters
  devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:email) }
  devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:email, :password,
  :password_confirmation, :first_name,
  :last_name, :preferred_language,
  :group_token,
  :master_data_contact_information_attributes =>
    [:contact_email, :primary_phone_number, :secondary_phone_number, :fax_number ]
 ) }
end

def configure_permitted_parameters
  devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:email) }
  devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:email, :password,
  :password_confirmation, :first_name,
  :last_name, :preferred_language,
  :group_token,
  :master_data_contact_information_attributes =>
    [:contact_email, :primary_phone_number, :secondary_phone_number, :fax_number ]
 ) }
end
