:) You were right. It was easy enough to use render :update and
replace_html with :partial to accomplish it.
I am however curious as to how we can do this using JSON. I started
reading about JSON for another feature I needed but I realised I dint
need JSON for it. I feel it would be a good exercise for me to
implement it in tackling this problem. Could you explain a little bit
more about the code you have shown me above or point me to where I can
find the documentation explaining this? From what I remember, JSON is
a format (Object Notation) to represent ActiveRecord objects (in
Rails) for JS to handle. But setting the header, responseJSON et all
is new to me.
Thanks Fred!
