Instance Method Details

#truncate(text, options = {}) ⇒ Object

Like the Rails truncate helper but doesn’t break HTML tags, entities, and words. <script> tags pass through and are not counted in the total. the omission specified does count toward the total length count. use :link => link_to(‘more’, post_path), or something to that effect
