Hi all, I need to write an application that gets data from a database and plots it on a graph. I am familiar with java and know that I could do it with jfreechart - however I am excited by RoR and would like to write the application with RoR instead. Is it possible to write it in RoR?

Hi- I need to create simple charts on the fly - I had used JFreeChart in the past with inJ2EE apps. Is there any equivalent here for Ruby. My charting needs are simple: just line charts. Also if anyone has done this, pls let me know how I should go about in doing it. Thanks -- Posted via http://www.ruby-forum.com/.

Hello- With a database filled with several customers'' datasets, I thought it would be a nice feature of my app''s backend interface to be able to extract (and optionally delete) the data from a single customer. It would then also be nice to rebuild that data from the stored info. What''s a good way to do this efficiently? If all the ":dependent => true"

Hello everyone, I''m looking to produce some graphs broadly like the ones shown here: http://www.dotnetcharting.com/gallery/List.aspx?gal=6 No prize for guessing what type of app it is... This particular graphing library is .NET-specific, but as you can see the results it produces are really nice. More than likely, they''re several notches above what I''ll be able to

Hi, I want to write a plugin that uses JavaScript and I am wondering how to put the static content, i.e. the JavaScript, in place? I read the documentation I found ( http://wiki.rubyonrails.org/rails/pages/Plugins and links) and looked at the listed plugins. One thing I found was that subversion seems to be a prerequisite for providing or even installing plugins. Is that right? The other thing

Hi. What is the best way to pre-populate your database with records while developing, not testing? For example, I want to: 1) > [run this command to populate db] 2) > ruby script/server 3) now I can surf to localhost:3000 and my app will already have relevant data I''m hoping to use yaml to suck it in. Is there a way to use the Fixture class to handle this even though this is

I''m having trouble installing lighttpd for local development on Mac OS X Tiger. Here are the commands I''ve run: sudo port install fcgi sudo port install lighttpd Here''s a snippet from running "port installed" with several ports removed for brevity: fcgi @2.4.0_1 (active) lighttpd @1.4.9_0 (active) rb-rubygems @0.8.11_0 (active) readline @5.0.005_0+darwin_8

Hi, Thanks Zed - this is very interesting. One item in particular caught my eye: Does anyone on this list have any comments or validation that Rails 1.2.1 is 2-4 times as slow as Rails 1.1.6? Topfunky provided a link that purports what looks like really horrible performance and memory characteristics for Rails 1.2.1, even v. 1.1.6:

Hi, As a long time Java/J2EE exponent I wanted to give Rails a fair crack of the whip and after we evaluated it for several weeks I have to say I like it. The installation process for the base system/framework is straightforward on the two platforms we''ve tried (Windows and Mac OS X). However, the charting components available, relying on ImageMagick or GraphicsMagick seem less clear

if I write a generic helper that isn''t specific to any one rails application or controller, what''s the best way to write tests for it? at the moment, I test it by including it in a generic controller in a blank rails app, and writing functional tests for the controller. Is that the best approach?

Fellows of the cloth -- I''m writing code that subclasses RedCloth and emits styled text that is not HTML. For example, I''m going to be emitting RTF and other formats from Textile or Markdown. I''ve got it working quite well with plainclothed RedCloth, but I can''t seem to override any of the methods in SuperRedCloth. Here''s a sample:

Just a positive experience I would like to share with you : testing is great on paper but very tedious to apply because nobody wants to run manually the tests by hand. Last week I have discovered zentest, an automated test process command line utility. That was at the beginning (hopefully) of a new project. Believe it or not, I have started to code most parts of the application without using

Hi all, I love the elegance of Markaby for HTML generation. I''d like to do something similar for SVG, e.g.: svg11 do title "Slide Title" rect({:x=>2,:y=>2,:width=>508,:height=>318,:fill=>"aqua"}) g({:style=>"fill:blue; stroke:black", :transform=>"translate(17,-38)"}) do circle({:cx=>70, :cy=>100,

Hi, Does anyone know of any complete tutorials that show the basics of writing a rails plugin? thanks scot -- Posted via http://www.ruby-forum.com/.

Hello, I''m a RoR newbie. I need to develop a gallery site for a friend of mine. Can you suggest me an open source gallery I can start from? I just need to manage photos, albums and an admin user in order to modify albums. Thanks .Stefano

Hi all, This might be OT. Wondering what are available charting solutions that work well with Ruby on Rails. I''ve seen reference to a few but they all seem to rely on integration with a program written in another language (requiring a seperate process per chart), Perl''s GD module for instance. Is there a 100% Ruby charting library that is freely available? Thanks, Dave

Hi all, We are a Java development team, but we are considering rails for our next project. However in this webapplication I need to do a fair amount of charting. In Java we used JFreechart (http://www.jfree.org/jfreechart/index.php) for this purpose. What are my options for charting in Ruby?

I am curious what people use to monitor their rails applications.. Specific things I''m interested in are: -web traffic -detecting processing errors (currently go to log files, but ideally would be sent to monitoring solution) -running database queries to see if there are new entries in the last X minutes -performance metrics (query performance) -up/down detection of

Hi, Anyone got any cool tricks for converting a Rails site (in this case, a typo installation) from a mysql database to a postgresql database? I''ve got it almost working -- I''m doing a SQL dump from mysql and loading it into postgres. However, mysql does booleans as a tinyint with 0 = false and 1 = true. When I try to import that into a postgres database that expects booleans

There''s been some great stuff added to edge since 2.0.2. Any chance it might be wrapped up into a 2.1 release?
