Forum Series Part 4: div_for Discussion
mattangriffel
In diving into div_for, I just discovered the ActionView method dom_id which will turn an instance of ForumPost into something like forum_post_10. It's what Rails uses behind the scenes for generating the div id in div_for. Before that (if I had to do it manually) I would have done something like "forum_post_#{@forum_post.id}"
Oh sweet. I remember seeing dom_id before but absolutely forgot about it!

Chris, how can you use the anchor tag with pagination? For instance you use anchor tag <%= link_to posts_path(anchor: post-#{post.id}) that points to a record which can be found on the 2nd or 3rd page of the posts_path thanks to the pagination. In this case the link_to helper will take you to the top of the posts_path instead of the record since the div tag the anchor tag is looking for can't be found in the DOM.
div_for has now been removed from Rails
