Hi I've recently upgraded to Rails 2.3.2 with Ruby 1.8.7. Whenever I start the server like this: cd /myproject script/server It hangs. After I cancel it the only error information that I see is: ^C/Users/timstephenson/.gem/ruby/1.8/gems/activesupport-2.3.2/lib/active_support/core_ext/load_error.rb:32:in `new': Interrupt The error ...
I have a model with many fields (nearly 40). The client wants the fields divided among multiple screens. The model also has a few has_manys that should look like they are part of the same model. How can one divide the model, and what are the tradeoffs among the ways to do it? I see a couple of possibilities: 1) Use JavaScript to show ...
It appears that NetBeans and Aptana/RadRails are the most common adopted IDE's for Ruby on Rails development, but both needs the Java Runtime Environment to run. I'm looking for an IDE wich doesn't need JRE to run. If it is lightweight and installs very fast would be better, because I will be programming in computers with old hardware a...

I'm looking for an easy way to generate previews for labels generated as pdfs. It would be great if I could convert these pdfs to images and show them to the user before the actual print/download. The application is currently running in a Jruby on rails environment, but it's quite possible that we switch to two applications, one running...
Hello, The task: Serve the files located in a local folder on the server to clients over http/80. In the end, I plan to emulate the folder on the client but that doesn't concern my question. So, there is an existing Rails app (rest based/xml) on that server that the clients would use in conjunction with these files. I don't need any l...

I've implemented twitter authentication in my rails app, on my local dev box. However I'm not able to get the application to log off. Isn't it enough to clear these two cookies? remember-token and -twitterauth-session? ...

For example with the following class class RosterSlot < ActiveRecord::Base belongs_to :event belongs_to :skill belongs_to :person end I want to do something like RosterSlot.find(:all, :order => skill.name) which means activerecord needs to do a join and or...
I have a small test project that I'm using to test the waters for a much larger project. I am using rspec on rails for testing, but recently looked into Cucumber. It looks very nice, but I'm wondering if there's a way for cucumber to run my spec tests, or for rspec (autospec) to run my cucumber features. I've looked around extensively...
I have a form with 2 select options in it -- frequency and duration. When there are errors with the form, and it is returned to the browser, the select options are not re-populated with the selections the user made even though the returned values for those fields match the values of options in the selects. Also, when the form is returned...
do you use Heroku to write Ruby on Rails app? i read about from the book Learning Rails from O'Reilly, and then today found that http://heroku.com/myapps doesn't have a "Create App" on the page so that I can edit the code online any more. Do they only allow that for the paid user? It also seems that they only let you have one web requ...
