devise+can 无法识别能力

Question

我有一个问题，当我使用 cancan 访问管理用户时，说“您无权访问此页面。” 这是我的代码：

class Ability
  include CanCan::Ability

  def initialize(user)


    if user.tipo == 'c'

        can :manage, :User

    end 
  end 
end

这是我的控制器用户

class UserController < ApplicationController
  load_and_authorize_resource

  def index
    @users = User.excludes(:id => current_user.id)
  end

  def new
    @user = User.new
  end

  def create
    @user = User.new(params[:user])
    if @user.save
      flash[:notice] = "Successfully created User." 
      redirect_to root_path
    else
      render :action => 'new'
    end
  end

  def edit
    @user = User.find(params[:id])
  end

  def update
    @user = User.find(params[:id])
    params[:user].delete(:password) if params[:user][:password].blank?
    params[:user].delete(:password_confirmation) if params[:user][:password].blank? and params[:user][:password_confirmation].blank?
    if @user.update_attributes(params[:user])
      flash[:notice] = "Successfully updated User."
      redirect_to root_path
    else
      render :action => 'edit'
    end
  end

  def destroy
    @user = User.find(params[:id])
    if @user.destroy
      flash[:notice] = "Successfully deleted User."
      redirect_to root_path
    end
  end 
end

这里是我的路线

 Rails.application.routes.draw do
  resources :proyects
  devise_for :users, :controllers => {:registrations => "users/registrations"}
  resources :users, :controller => "user"

有人知道如何解决吗？或者有人刚刚发生了

提前致谢！

能力定义中的类名错误。

如下更改ability.rb：

class Ability
  include CanCan::Ability

  def initialize(user)
    if user.tipo == 'c'
      can :manage, User
    end 
  end 
end
