Hi all,
I am newly learning Rails and playing with Web Chat app. I looked
through what other people have done. I tested the following very
naive, skeleton app. It seems to work in my local machine when I open
two Firefox (or two Safari). But it does not work cross browser, eg,
Firefox-Safari. Strange? What''s going on? Thanks.
- index.rhtml
<% form_remote_tag :url => {:action => ''say''} do
%>
<%= text_field_tag ''said'' %>
<%= submit_tag ''Say'' %>
<% end %>
<%= periodically_call_remote :url => {:action =>
''get_new_line'' }, :frequency => 1.0 %>
- chat_controller.rb
def say
session[:what_said] = params[:said]
@line1 = session[:what_said]
end
def get_new_line
@line2 = session[:what_said]
end
- say.rhtml
<%= @line1 %>
- get_new_line.rhtml
<%= @line2 %>

I would recommend going against the Rails option here as you''re making a request at least once every second to an action in your application. Imagine if 10 people were in the chat, that would mean 10 requests per second. Think of an alternative option here, like an IRC server or similar. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

You could have a look at juggernaut, does use a flash file and extra process running on the server. http://juggernaut.rubyforge.org/ Best regards Peter De Berdt --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Yeah, I should try Juggernaut. But I wonder if my web host will allow push server stuff. Thanks.

And a third from me. I met the developer of Juggernaut at RailsConf and saw a demo. Very slick. It uses a small flash object to keep a persistent connection open between client and server so you eliminate a lot of issues there. From a development perspective it was basically as simple as saying "open chat channel 9" (work out the details for your app) and then the client/browser just listens. Another option, if you''re shopping, is Jabber. I was leaning towards this until I ran into Juggernaut.

You''ll still need a Comet (official term) implementation like Juggernaut to push chats out to the user or do polling like Gmail''s in-browser chat client does (IIRC), Jason --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Right, Jabber won''t allow a persistent connection without some "comet" alternative. I already advocated Juggernaut but here is another alternative: http://shooting-star.rubyforge.org/wiki/wiki.pl?Making_A_Chat_System_Within_5_Minutes That is using a more standard comet implementation called shooting_star. Like Juggernaut, it opens a persistent connection which can be used for implementing a chat system. I have looked at both and I chose Juggernaut but it easily could have been the wrong decision. However, juggernaut was so easy to use and it worked so I had no reason to move away from it. As long as the browser has Flash, it works like a charm. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thank you all for great suggestions! In fact, I installed Juggernat
today.
I followed its README file example included below. It works, but
whenever Rails call is made, alert window ( "Juggernaut: Received
data:
try { ... " ) pops up all the time. How can I block this?
-chat controller:
class ChatController < ApplicationController
def index
end
def send_data
render :juggernaut do |page|
page.insert_html :top, ''chat_data'', "<li>#{h
params[:chat_input]}</li>"
end
render :nothing => true
end
end
-index.rhtml
<html>
<head>
<%= javascript_include_tag :defaults, :juggernaut %>
<%= juggernaut %>
</head>
<body>
<%= form_remote_tag(
:url => { :action => :send_data },
:complete => "$(''chat_input'').value =
''''" ) %>
<%= text_field_tag( ''chat_input'',
'''', { :size => 20, :id =>
''chat_input''} ) %>
<%= submit_tag "Add" %>
</form>
<ul id="chat_data" style="list-style:none">
</ul>
</body>
</html>

Yea, I get that too. It only happens in development (on your local PC). It is for your debugging purposes. Once deployed to the server, these messages are not displayed.
