how to achieve text extract on rails?

Question

I have an article list page. It needs to show some content information about this article. If I only use:

 truncate @article.content,:length=>100

It will show some html tag, and doesn't show the real content to the user. I want to find some way to get the text extract from the content, so I want to ask is there some embedded way to achieve this?

Answer 1

You could use strip_tags to remove the html tags:

truncate(strip_tags(@article.content), :length=>100)
