Output text size in ruby on rails

Question

How do I get only first (say) 200 characters from my object Article (which is in a table articles with aattributes content and title)?

Thank you

Answer 1

The rails' TextHelper has a truncate method.

So, in your views, you just have to do :

<%= truncate @article.content, :length => 50 %>

Where 50 is the number of characters you want to display.
