when we have validate_presence_of :name in the model and then when we
put in the create action that we re-render 'new', then the form_for will
populate the fields, and error_messages_for 'story' will have the
correct error message.
this is really great, and and the same time, this looks like magi

hm... so the XHTML will just be used as html... and we aim to output it
as XHTML anyway...
pragmatically, it will work.
is it true that Rails depend on cookies? It seems that flash is a part
of session, and session uses cookies... so when i disable cookie in
Firefox, what was working became
ActionController::InvalidAuthenticityToken
so is it true that for a RoR app to work, cookies are mandatory?

I would like to use HTML 4.01 Strict, and used a DOCTYPE of it in my

helper function

is there a way to ask Rails to use HTML instead of XHTML?

Poste
some books or even the rails api uses
form_for ...
...
submit_tag ...
end
and i found that the Rails 2.3.2 Scaffold uses
f.submit "Go"
instead... and this is not in the rails api doc. Is this a new
addition and is it suppose to replace submit_tag?

then immediately, the controller will have special conventions and now

i wonder what is a ballpark number that Rails can support for number of
hits per second, if we are hosting RoR on
1) dreamhost or netfirms
2) as a separate virtual server
3) as a standalone machine
maybe even 1 hit per second can be ok if that means

i found the following functions or method to escape HTML, URL params, or
Javascript data:
<%= h @ha %>
<%= sanitize @ha %>
<%= u @ha %>
<%= @ha.to_json %>
<%= strip_tags @ha %>
are they more functions or methods to do these things?
and are there alternative ways to do that? thanks.
