这是user.rb：

# Table name: users
#
#  id                 :integer          not null, primary key

                       :length => { :within => 6..40 }

  before_save :encrypt_password

  def has_password?(submitted_password)
    encrypted_password == encrypted(submitted_password)
  end

我猜是

def has_password?(submitted_password)
  encrypted_password == encrypted(submitted_password)
end

应该

def has_password?(submitted_password)
  encrypted_password == encrypt(submitted_password)
end

更一般地“如何读取堆栈跟踪来解决问题”：

1）查看堆栈跟踪的顶行（文本的大墙）

activemodel (3.2.11) lib/active_model/attribute_methods.rb:407:in `method_missing'

那是你代码中的一行吗？在这种情况下，否：它来自 activemodel。

2) 继续寻找，直到您找到适用于您的代码的第一行代码。在这种情况下，它：

app/models/user.rb:32:in `has_password?'

这是您的代码中导致问题的行。

3）去看看导致问题的代码行。堆栈跟踪告诉我们这是文件的第 32 行app/models/user.rb

在这种情况下，它是这三行的中间行：

def has_password?(submitted_password)
  encrypted_password == encrypted(submitted_password)
end

4）通过阅读错误消息找出问题所在；）

错误消息告诉您“加密”作为一种方法不存在是吗？

因此，查看您的用户模型，看看您是否有一个名为 encrypted 的方法......

在这种情况下你没有，但你确实有一个电话“加密” - 很有可能你只是不小心输入了“加密”而不是“加密”......解决这个问题，你的问题就解决了。

这四个步骤可用于解决大多数此类错误。

似乎您的 ruby​​ 无法识别您encrypted的 User 对象的方法。您应该能够通过包括

require 'digest/sha1'

对于您的用户模型

例如：

require 'digest/sha1'
class User < ActiveRecord::Base
  #code
end

阅读此问题以了解有关没有 gem 的加密的更多信息
