The Rails guide has a great write-up on
this:
http://guides.rubyonrails.org/working_with_javascript_in_rails.html#form-for
Essentially, remote: true will handle submitting your form via ajax for
you, but it's on you to handle the response (since that's going to be very
application-specific). In your case, if the tweets are displayed in a
list, maybe the action responds to ajax requests by rendering just a tweet
template (versus the entire tweets collection), and your JS takes that HTML
snippet and inserts it into the list.
