Ruby on rails 设计4个更新自定义添加字段到用户模型

Im使用Desive 4和Rails 5，并将以下字段添加到Desive提供的标准用户模型中：

class AddFieldsToUsers < ActiveRecord::Migration[5.0]
  def change
    add_column :users, :name, :string
    add_column :users, :username, :string
    add_column :users, :headline, :string
    add_column :users, :location, :string
    add_column :users, :description, :text
  end
end

我遵循了DeVICE 4强参数更改，并在我的

应用程序\u控制器中。rb

iv获得以下信息：

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception

  before_action :configure_permitted_parameters, if: :devise_controller?

  protected

  def configure_permitted_parameters
    added_attrs = [:name, :username, :location, :headline, :description, :email, :password, :password_confirmation]
    devise_parameter_sanitizer.permit :sign_up, keys: added_attrs
    devise_parameter_sanitizer.permit :account_update, keys: added_attrs
  end

end

错误是什么？@Deep没有发生错误，当我刷新页面时，没有任何内容得到更新。您是否在

config.scoped\u views=true

内部

config/initializers/designe.rb

文件？否则，Deviate将不会在自定义视图中应用您的更改。这是因为，如果您的应用程序中有多个Deviate模型（如用户和管理员），您将注意到Deviate对所有模型使用相同的视图

$rails generate Deviate:views users

或

$rails generate Deviate:views Admin

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception

  before_action :configure_permitted_parameters, if: :devise_controller?

  protected

  def configure_permitted_parameters
    added_attrs = [:name, :username, :location, :headline, :description, :email, :password, :password_confirmation]
    devise_parameter_sanitizer.permit :sign_up, keys: added_attrs
    devise_parameter_sanitizer.permit :account_update, keys: added_attrs
  end

end

  def configure_permitted_parameters
    devise_parameter_sanitizer.permit(:sign_up, keys: [:name])
    devise_parameter_sanitizer.permit(:account_update, keys: [:name, :username, :location, :headline, :description])
  end
