Paperclip :: RegistrationsController#update中的错误 处理缩略图时出错。有人可以帮我这个!!! 我的注册控制器文件是,

class RegistrationsController < Devise::RegistrationsController
protected
    def update_resource(resource, params)
        resource.update_without_password(params)
    end

我的应用程序控制器文件是

     class ApplicationController < ActionController::Base

  protect_from_forgery with: :exception

  before_action :configure_permitted_paramters, if: :devise_controller?

  protected
    def configure_permitted_paramters
        devise_parameter_sanitizer.for(:sign_up) << :fullname 
        devise_parameter_sanitizer.for(:account_update) << :fullname <<  :current_password << :avatar
    end
end

有人可以帮助我摆脱错误

我的用户模型是,

has_attached_file :avatar, :styles => { :medium => "300x300>", :thumb => "100x100#" }, :default_url => "/images/:style/missing.png"
  validates_attachment_content_type :avatar, :content_type => /\Aimage\/.*\Z/
