当我刷新页面时，出现以下不同的错误:

when I refresh the page, i got a different error below:

Started GET "/questions" for 127.0.0.1 at 2012-06-07 17:22:40 +0900

NoMethodError (undefined method `key?' for nil:NilClass):

我的代码是

class Question < ActiveRecord::Base
attr_accessible :content, :name, :title
validates :name,  :presence => true
validates :title, :presence => true,
                  :length => { :minimum => 5 }

end

我的代码有什么问题?

What's wrong with my code?

编辑

当我插入时# encoding: utf-8, 在我的代码中，我得到了一个不同的错误，如:<代码>/Users/sookcha/Desktop/Dev/CSap/app/models/question.rb:5: 语法错误，意外的 tSYMBEG，需要关键字_do 或 '{' 或 '(' 验证 :name, :presence => true ^/Users/sookcha/Desktop/Dev/CSap/app/models/question.rb:7: 语法错误，意外的 tASSOC，期望 keyword_end :length => { :minimum => 5 } ^):
怎么了?

When I insert # encoding: utf-8, in my code, I got a different error like: /Users/sookcha/Desktop/Dev/CSap/app/models/question.rb:5: syntax error, unexpected tSYMBEG, expecting keyword_do or '{' or '(' validates :name, :presence => true ^ /Users/sookcha/Desktop/Dev/CSap/app/models/question.rb:7: syntax error, unexpected tASSOC, expecting keyword_end :length => { :minimum => 5 } ^):
What's wrong?

推荐答案

有一个非中断空间 在您的代码中:

There's a non-breaking space in your code:

validates :name,  :presence => true
                ^
               here
