Hi. I’m developing a Ruby Application. I would like to perform several
actions, that is, call more than one action in 1 controller when
someone clicks the submit_tag using ajax, rjs, etc.
Right now it is working perfectly but with just one call.
This is how the code looks like:
<% form_remote_for :tag,
:loading => visual_effect(:appear, :loading_div),
:success => visual_effect(:fade, :loading_div),
:failure => “alert('HTTP Error ’ + request.status +
‘!’)”, #visual_effect(:fade, :loading_div),
:url => {:controller => “build”, :action => “parse”} do |
f| %>
Search: <%= f.text_field :title %>
<%= submit_tag "Submit" %>
<% end %>
So the idea is to have two
:url => {:controller => “build”, :action => “parse”}
:url => {:controller => “build”, :action => “parse2”}
and when someone clicks the button to run both of them concurrently.
Is this possible in any way?
Thanks in advance 
Happy 2008

Yes, add option
:html => {:onsubmit => remote_function(:url => {:controller => ‘build’,
:action => :parse2})}

what if I want to have 3 or 4? or 100?
Thanks for your reply!
Having multiple is just stupid. If you want it to do multiple things at
the
same time, stick them all in the same action and only call one URL.
You can render as many partials as you want, concurrently.
For example:
<%= render :partial => “number_1” %>
<%= render :partial => “number_2” %>
If you’re using render :update in your action do a
page.replace_html :element_on_the_page, :partial => “number_1”
page.replace_html :other_element_on_the_page, :partial => “number_2”
Not really Ryan. There is at least one case in which is interesting to
do. Since you can’t have more than one render per action and there are
times when you want to render partials concurrently.
So, is there any way to do it? I was trying another solution by
creating Threads in the controller but i think that it will be easier
this way.
Check
http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/e11f83680ee71eef
to see what happens if you try to do it with multiple threads and
multiple renders.

You can create a JavaScript function that is called by
the onsubmit event, and which calls remote_function in
a loop.
Concurrency will however be limited by both the number of
simultaneous connections for a browser and the number
of Rails handlers you are running.
However this method does allow multiple changes to be
sent to the browser concurrently, in contrast to
the Thread option (in your other post), which only sends
to the browser when all threads have completed.
