title: Building a blog in rails -- how do I limit text and put a "read more" link to show the rest of post?
body: <p>I'm building a blog using RoR. I have the index.html.erb page for the posts showing all of the posts. It displays all of the posts and all of their content. I'd like to limit the content that is shown to a certain number of characters and then put a "read more" link to go to the show page for that individual blog post. Any help with how to do this? Thanks.</p>
