ruby-on-rails – 类RegistrationController的超类不匹配 – 覆

我终于让路由工作了,但现在我得到了类错误的超类不匹配.

继承人我的设置：

注册控制器(app / controllers / users / registrations_controller.rb)

class RegistrationsController < Devise::RegistrationsController

  def sign_up_params
    devise_parameter_sanitizer.sanitize(:sign_up)
    params.require(:user).permit(:email,:password,profile_attributes: [:username])
  end

  def new
    super
  end

  def create

  end

  def update
    super
  end

end

路线

root 'welcome#index'

devise_for :users,:controllers => {:registrations => "users/registrations"}

查看

–edit.html.erbu0026 amp ;> new.html.erb存在于该文件夹中(app / views / users / registrations)

用户模型(以防万一)

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable,:lockable,:timeoutable and :omniauthable
  devise :database_authenticatable,:registerable,:recoverable,:rememberable,:trackable,:validatable

  has_one :profile
  accepts_nested_attributes_for :profile

  def profile
    super || build_profile
  end

end

知道为什么会出现这个错误吗？

谢谢！
