similar to: Sans Periodically call remote-- possible?

My Rails application requires a very busy worker process running in the background at all times. I am launching this non-interactive process using script/runner. This process is very busy and is communicating with the MySQL server constantly. As I started putting some load on the system to test, I started running into performance issues. I have since discovered that Rails is only using 1

I''ve actually found a way to make EventMachine listen to events from a serial port, but only by using the pure Ruby version, using Guilliame Pierronnet''s Ruby/SerialPort library. It turned out to be simpler than I thought it would be: require ''serialport'' $eventmachine_library = :pure_ruby require ''eventmachine'' module EventMachine class

Hi guys, I need your help. Here is my database.yml: development: adapter: postgresql database: db username: username password: mypassword # Connect on a TCP socket. Omitted by default since the client uses a # domain socket that doesn''t need configuration. Windows does not have # domain sockets, so uncomment these lines. host: 192.168.22.1 (this is a remote ip in

Hi guys, I''ve been able to successfully install the postgres adapter for a remote database machine to get rails up. My machine is running on Fedora 2. Rails version 1.1.2. Is my yml config correct? I am getting this error when I execute script/generate scaffold service_contents content : exists app/controllers/ exists app/helpers/ create app/views/spiel exists

Francis, I read in the list archives back that a future EventMachine release will support epoll on Linux (i.e., it''s in the trunk). Better still, is there a possibility that EM will rely on libevent so that it will be architecture independent (i.e. epoll on Linux, kqueue on FreeBSD/Mac OS X, /dev/poll on Solaris)? This is how memcached is implemented, and it would be helpful to be able

Hi, I would like to put a checkbox on a form where the input field is a variable rather than a field in a model. The normal way (with a model) would be: <%= check_box(''client'', ''accept'', {}, "1", "0") %> But since accept is a variable @accept and model client will not be there, how do I make a check box work? Regards, Paul

Hi guys, I''ve been reading through the forums and came across a response for adding :with condition to a periodically call remote. I tried it out and couldn''t make it work. Would anyone have a sample of how to use this conditional structure with periodically call remote? If not, does anyone have any idea how to add a condition to a periodically call remote? What I need is to

Hey. Below is a patch to allow generic Ajax.Autocompleters. Basically it''s for people who wanna be able to watch an input for changes, but don''t want it to pop up an autocompleter box below. Useful for live previews, that kind of thing. Someone''s gonna have to fix the tabstops. I couldn''t be arse to work out how to make vim do the softtabs properly. Spaces for

Prototype.js and Thomas''s effects scripts use repeated setTimeout calls for timed looping, for instance in time-based observers. On Konqueror 3.4.1 (possibly other khtml-based browsers, too), these observers reproducibly crash the browser. Just keeping open a browser with such an observer is enough. After some time it invariably segfaults. When I substitute setInterval for setTimeout

Hello, I have been looking at the Ruby/EventMachine. First let me say it look very good. Reactor model with no threads makes for fast reliable server, and I have read about marvelous Twisted framework for Python and am glad to see something similar for Ruby. I am writing network app with Ruby threads now and it very slow, and I try new Ruby 1.9 with native threads that make it much slower.

Hi guys, I have a situation here. I have my project set to no pluralization due to legacy tables in environment.rb. Now, I have some new tables which I''m starting to pluralize. When I do a generate a scaffold to this new table: script/generate scaffold my_tables table it seems to work out fine for certain sections like http://mysite.com/railsapp/new (which also inserts properly to

I''ve noticed that using several TimedObservers (prototype.js) on a page to watch for changes to text fields (haven''t tried forms) can have a non-negligible effect on the CPU cycles used by the browser process. Nothing dramatic, to be sure, but unnecessary. Autocompleter.Base (controls.js) follows a smarter strategy to watch for changes. Currently this functionality is tied

I''ve just released Juggernaut - a plugin for ruby on rails. Check out the site: http://juggernaut.rubyforge.org I?ve also finished a demo that illustrates some of Juggernuat?s capabilities. You can sign up for an account here: http://alexmaccaw.no-ip.info:3500/login/sign_up . It might be a tad slow as it?s running from my home machine. Juggernaut for Ruby on Rails initiates a flash

I have many pages to generate quickly. They are based off of the scaffold generator, but I want to convert the rhtml files to Markaby, and change some formatting. Without having to do a lot of repetitive hand editing. Is there a simple way to overwrite/extend part of the scaffold generator? Do I need to write my own from scratch? -- Best Regards, -Larry "Work, work, work...there is no

Hello to all list members... Exchuse for my bad english, I don''t write english very well. I''m searching for a solution to hilight a div when his value change. The value in these div is take from Ajax.Updater . the code is: new Ajax.Updater(''acc'',''tools/head_info.php'',{asynchronous:true}); and have a settimeout to recall it every 5 seconds.

Hi guys, I have a form with 10 fields and was wondering how you can pass multiple values and saving them into your database using link_to_remote. Is it doable? thanks, Bing -- Posted via http://www.ruby-forum.com/.

I have a list of categories, when I delete one of them, I want that item to fade and then get removed. So I do the following: 1. home_controller: def delete @category = Category.find_by_name(params[:name]) @element_id = @category.name Category.delete_all(["name = ?", @category.name]) end 2. delete.rjs: if @element_id page.visual_effect :fade, @element_id

I am using eventmachine 0.8.1 on windows XP and am having very odd problems. This snippet of code gives the error that follows it. class EchoServer def receive_data data puts data send_data ">>>you sent: #{data}" if data =~ /quit/i puts "quitting" close_connection EventMachine::stop_event_loop end end end

Hello, on the application that I''m working on, we are using Thin. The server implements long polling and commands that alter its internal state. Connecting to the long poll is a very fast operation, while updating the state of the server is a relatively slow operation. The long poll connection is held open until there is a change to be sent to the connection. Here is my current

Hi Guys, I hope someone can help me out. I am trying to configure two applications to run on lighttpd and each app will have its own domain. My machine is running on Fedora. When I run my lighttpd with the following conf file, I get no error but when I check out my app, it dishes out a 404 error- the 404 being served isn''t the 404 inside the railsapp/public folder. Do hope someone
