In Ruby on Rails routing (using route.rb), can it say, for any URL
having the form:
www.example.com/ ... #! ...
then use controller `redirect` ?
This is so that in AJAX, some page can tag the `#!` at the end of URL so
that the real content of interest is the part after the `#!`

RJS is very good for sending Javascript code back to the browser saying
"Your AJAX is successful and by the way you can update the UI to signal
to the user using the following Javascript I am going to send you."
How about other webpage interactivities, dynamic HTML, is RJS suited for
doing that as
I was going to change the background of a div from white to red and then
from red back to white, so this is used in an RJS file:
page[:vote_score].visual_effect :highlight, :startcolor => '#ff',
:endcolor => '#ff'
page[:vote_score].visual_effect :highlight, :startcolor => '#ff',
:
So it looks like on RoR, when Ajax (using form_remote_tag) returns a
success code, Javascript is also returned to handle the visual effects.
using Fiddler, I do see the following response:
try {
Element.update("vote_score", "Score 58");
$("vote_score").visualEffect("highlight");
}

not like this?
In Ruby on Rails, say a Story object can "has_many" Vote objects (a
story is voted "hot" by many users).
So when we do a
s = Story.find(:first)
"s" is a Story object, and say
s.votes
returns "[]"
and
s.votes.class
returns "Array"
So clearly, s.votes is an empty Array object.

On a Mac running Snow Leopard, the Rails version was 2.3.5 (by using
rails -v)
and then I used gem install to install about 20 things, and maybe there
was a line on the instructions that was there in the past that says

and I ran it anyways, thinking that maybe 1.3.5

Great thanks.
So I have come up something like this:

to wrap each instance variable of an ActiveRecord object between ""
and "", is there a way to "loop through" them, at least in the

Such as

<%= "" %>

ah, on second thought, doesn't the join() method actually will create n

i was at first worried that if the print out is long, like a few hundred
lines, then it can create many string objects.
using join looks like will create only n
In the view code, say it is
<% @stories.each do |s| %>
<%= "#{h s.inspect}" %>
<% end %>
it would be breaking the code into 3 <% %> and <%= %>
is there a way to just have one <% %> or <%= %> so as to keep the code
more flowing together?

i am writing a test program for ActiveRecord, and it reads a document
which is like 6000 words long. And then i just tally up the words by
recordWord = Word.find_by_s(word);
if (recordWord.nil?)
recordWord = Word.new
recordWord.s = word
end
if recordWord.count.nil?
