我猜那个
def has_password?(submitted_password)
encrypted_password == encrypted(submitted_password)
end
应该是
def has_password?(submitted_password)
encrypted_password == encrypt(submitted_password)
end
更一般地说“如何阅读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'
这是你的代码中的一行吗？在这个例子中没有：它来自activemodel。
2）继续查看，直到找到 代码的第一行代码。在这种情况下：
app/models/user.rb:32:in `has_password?'
这是导致问题的您的代码中的一行。
3）去看导致问题的代码行。 stacktrace告诉我们这是文件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;来确定问题出在哪里;）
错误消息告诉您“加密”不存在作为方法是吗？
请查看您的用户模型，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” - 很有可能你只是偶然输入“加密”而不是“加密”...修复它，你的问题就解决了。 / p>
这四个步骤可用于解决此类大多数错误。
答案 1 :(得分：0)
好像你的ruby无法识别用户对象的encrypted方法。你应该能够通过包括
require 'digest/sha1'
适用于您的用户模型
例如：
require 'digest/sha1'
class User < ActiveRecord::Base
#code
end
