Ruby on rails 设计'；s强参数为'；t列出字段输入

我添加的自定义输入字段似乎没有被列入白名单（提交时显示空白验证错误）

这是控制器：

class AccountsController < ApplicationController

  before_filter :configure_permitted_parameters, if: :devise_controller?

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) << :name
  end
end

class AccountsController

试试这个：

devise_parameter_sanitizer.for(:sign_up) {|u| u.permit(:name) }

---

试试这个，我希望它能帮助你解决你的问题

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

  before_filter :configure_permitted_parameters, if: :devise_controller?

  def configure_permitted_parameters
   devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:firstname, :lastname, :email, :password, :password_confirmation) } #here you can permit custom fields. 
  end

  protect_from_forgery with: :exception
end

class ApplicationController

发布您的设备注册表单您的表单代码很好，因此我建议您选择一个新项目，按照上的步骤操作，并尝试添加自定义字段。发布您的用户模型、设备迁移和路由文件。是的-用户模型将帮助我们了解您的设备安装；如果是验证错误，则很可能与allow_空格或类似的内容有关。

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

  before_filter :configure_permitted_parameters, if: :devise_controller?

  def configure_permitted_parameters
   devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:firstname, :lastname, :email, :password, :password_confirmation) } #here you can permit custom fields. 
  end

  protect_from_forgery with: :exception
end
