当我尝试在rails 2.3.11中的视图中获取activeRecord对象的参数时，我遇到了错误

Here is the error I get

这是我得到的错误

ArgumentError in External_articles#show

Showing app/views/external_articles/show.html.erb where line #3 raised:

wrong number of arguments (0 for 1)
Extracted source (around line #3):

1: <p>
2:   <b>Title:</b>
3:   <%= @external_article.title %>
4: </p>
5: 

But in the console, It works fine.

但在控制台中，它工作正常。

?> ExternalArticle
=> ExternalArticle(id: integer, title: string, url: string, language: string, source: string, date: date, created_at: datetime, updated_at: datetime, event_id: integer)

>> ExternalArticle.last.title
=> "Two course records shattered in Va. Beach marathon "

All the other attributes are displayed correctly in the view. And if I rename the title attritute to 'article_title' it will work.

所有其他属性在视图中正确显示。如果我将标题attritute重命名为'article_title'，它将起作用。

I don't get what the problem is. The view used to work well.

我不知道问题是什么。以前的观点运作良好。

Any clue? Thanks

任何线索？谢谢

I finally found the source of the problem. I had created a global helper method called title, that used a parameter. When I renamed the helper method, everything worked again.

我终于找到了问题的根源。我创建了一个名为title的全局辅助方法，它使用了一个参数。当我重命名帮助方法时，一切都恢复了。
