Truncate function and html tags
I have a text field in the db for the body of user posts. Users submit the posts using the tinymce editor, which allows certain html tags. The posts are stored in the db with allowed html tags directly in the post, so I could have something like: <p>This post will try to eliminate the confusion regarding rails and the truncate function.</p> I am trying to display the first 300 characters of the post on a "what''s new" type page. I am using the truncate function of rails to grab the first bit of each post for the what''s new page... truncate(post.text, 300) which works just fine, except I have times where the 300 character limit hits in the middle of a tag. One such post is currently screwing up my layout... the 300 character limit is hitting in the middle of the "close paragraph" tag, so my output html is: <p>This post will try to eliminate the confusion regarding rails and the truncate function.</ Voiding the </div> that closes this area out. Simple ideas to fix this welcome... :) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
