I have something similar to a blog post that users can add comments to.
I’m use a partial to render the list of comments and a form that submits
a new comment via AJAX to update the list. The AJAX call uses the same
partial. My question is, how can I mark the last added comment so that I
can use page.visual_effect to give it a yellow fade. Currently, I can
highlight the entire block of comments. Everything I’ve tried causes
problems. :after_create won’t work, as far as I can tell, because it’s
wrapped into the create method and no changes have been committed to the
This seems like it should be a pretty simple task, highlighting the last
change to a list rendered as from a collection, but I can’t figure it
out. Any thoughts?
