Question

我想在用户模型中添加属性名称。我运行了迁移命令，将列添加到数据库中并且工作正常。将属性添加到用户本身也可以，但它不会保存在数据库中。

如何将属性“name”添加到RegistrationController的sign_up和account_update所需的参数中？

这是我的用户模型

class User < ActiveRecord::Base
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable
  attr_accessor :name
end

我尝试在RegistrationController

中将所需的参数添加到这样的方法中

class Users::RegistrationsController < Devise::RegistrationsController

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

  def account_update_params
    params.require(:user).permit(:name, :email, :password, :password_confirmation, :current_password)
  end
end

在路线中我添加了一行

devise_for :users, controllers: { registrations: 'users/registrations' }

但是用户名仍未保存在数据库中。

将此添加到class TabBarController: UITabBarController { var viewControllerToSelect: UIViewController? required init?(coder aDecoder: NSCoder) { super.init(coder: aDecoder) delegate = self } func showLeavingAlert() { let leavingAlert = UIAlertController(title: "Warning", message: "Do you want to save before you leave?", preferredStyle: .Alert) let saveAction = UIAlertAction(title: "Yes", style: .Default) { (action) in let delayTime = dispatch_time(DISPATCH_TIME_NOW, Int64(1 * Double(NSEC_PER_SEC))) dispatch_after(delayTime, dispatch_get_main_queue()) { // switch viewcontroller after one second delay (faked save action) self.performSwitch() } } leavingAlert.addAction(saveAction) let cancelAction = UIAlertAction(title: "No", style: .Cancel) { (action) in // switch viewcontroller immediately self.performSwitch() } leavingAlert.addAction(cancelAction) presentViewController(leavingAlert, animated: true, completion: nil) } func performSwitch() { if let viewControllerToSelect = viewControllerToSelect { // switch viewcontroller immediately selectedViewController = viewControllerToSelect // reset reference self.viewControllerToSelect = nil } } } extension TabBarController: UITabBarControllerDelegate { func tabBarController(tabBarController: UITabBarController, shouldSelectViewController viewController: UIViewController) -> Bool { if let navigationController = selectedViewController as? UINavigationController, _ = navigationController.visibleViewController as? FavoritesViewController { // save a reference to the viewcontroller the user wants to switch to viewControllerToSelect = viewController // present the alert showLeavingAlert() // return false so that the tabs do not get switched immediately return false } return true } }以配置ApplicationController signup＆amp; signin参数。

account_update

并将def configure_permitted_parameters devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:name,:email, :password, :password_confirmation) } devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:login, :username, :email, :password, :remember_me) } devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:name, :username, :anonymous, :email, :password, :password_confirmation,:reset_password_token) } end添加到before_filter，例如：

ApplicationController

Answer 2

请检查Devise Parameter Sanitization

你可以试试这个：

class Users::RegistrationsController < Devise::RegistrationsController

 def sign_up_params
  devise_parameter_sanitizer.for(:sign_up).push(:name)
 end

 def account_update_params
   devise_parameter_sanitizer.for(:account_update).push(:name, :email, :password, :password_confirmation, :current_password)
 end
end
