ActionView::Helpers::TextHelper
Provides a set of methods for working with text strings that can help unburden the level of inline Ruby code in the templates. In the example below we iterate over a collection of posts provided to the template and print each title after making sure it doesn’t run longer than 20 characters:
<% for post in @posts %> Title: <%= truncate(post.title, 20) %> <% end %>
