在我的Rails项目中，我正在尝试使用以下Gems设置用户身份验证和用户角色：

设计
惭惭
Rolify

我设计得很好并且工作得很好但是当我去设置CanCan和Rolify时，我在浏览器中出现了这个错误：

NameError in Home#index

user.rb

class User < ActiveRecord::Base
  rolify

  # Include default devise modules. Others available are:
  # :token_authenticatable, :confirmable,
  # :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me, :subdomain, :first_name, :last_name

  # Make sure certain attributes are unique
  validates_uniqueness_of :email, :case_sensitive => false
end

role.rb

class Role < ActiveRecord::Base
  has_and_belongs_to_many :users, :join_table => :users_roles
  belongs_to :resource, :polymorphic => true

  scopify
end

rolify.rb

Rolify.configure do |config|
  config.use_dynamic_shortcuts
end

Answer 2

假设您已正确安装并随后需要rolify gem可以安全吗？...

运行gem list并确认已在user.rb文件顶部添加require 'rolify'时，请确认列出了rolify。

未定义的局部变量或方法'rolify'
