小编p0k*_*0k3的帖子

首先,原谅我可怜的英语,我是法国人......解释我的问题很棘手!

我在Rails应用程序中有一个模型用户模型:

class User < ActiveRecord::Base

  attr_accessible :email, :gender, :lastname, :firstname    

end

以及从User继承的BackUser模型:

class BackUser < User
  # Class for Backoffice User
  devise :database_authenticatable, 
          :rememberable, 
          :trackable, 
          :lockable, 
          :invitable, 
          :confirmable,
          :validatable,
          :validate_on_invite => true

  attr_accessible :password, :password_confirmation, :remember_me, :active, :role

  validates :role, presence: true,
                  inclusion: ["admin", "normal"]

  validates :gender, presence: true

  validates :firstname, presence: true

  validates :lastname, presence: true


  def admin?
    self.role == 'admin'
  end

end

第二节课应该在邀请之前验证记录!但是,当我使用控制台执行以下操作时:

u = BackUser.new
u.invite!

"u"保存在数据库中,邀请被发送到空白电子邮件...

你知道我要做什么吗？

吃了很多!

当我尝试使用capistrano进行部署时,我遇到了错误:

上限生产部署:设置

我有这个错误消息:
