I am trying to reuse some code from another rails application I had worked on earlier. I copied over all the models / views / controller / migrations and ran rake db:create and migrate. Now when I try to run the application the initial page for this view (the one that has the list edit/delete) loads fine and shows there are 0 records. Wh...
Hi Shoesers, Is there any way to allow text selection, copying and pasting in a Shoes app? I'm making a little utility, and it would be great if it could support this functionality. I know shoes uses Pango/Cairo for text rendering, so I imagine there's a way to turn this on. Anyone? _why? Also, _why, thanks for the great toolkit! ...
What data do you use with Selenium tests on Rails apps? Do you load from fixtures? Use an existing dev db? Use a separate (non-fixture) db? I'm considering my options here. I have a Rails app with a large Selenium test suite that runs on a modified version of Selenium Grid. Part of the process, right now, is loading a large set of fixt...
Businessmen typically want a web application developed. They are aware of .net or J2EE by names, without much knowledge about either. Altho' Rails and Django offer for a much better and faster development stack, it is a big task to convince businessmen to use these platforms.

I have a Ruby script that used string interpolation to build error messages. p "#{vName} is not a defined variable" => 'xxx is not a defined variable' Another programmer came through and attempted to externalize the string literals to a separate configuration file. Of course, he doesn't get the substitution. p err_string_from_config...
I read that Ruby has a language featured called "labels", how does that work? Update: I saw it at http://ruby.about.com/od/gems/qt/shorturl.htm where the author talks about a label at the bottom of the article with: puts ShortURL.shorten('http://ruby.about.com', :lns) ...

I'm trying to update one of my objects in my rails app and the changes just don't stick. There are no errors, and stepping through with the debugger just reveals that it thinks everything is updating. Anyway, here is the code in question... qm = QuestionMembership.find(:first, :conditions => ["question_id = ? AND form_id = ?", q_id,...
Whenever I use script/generate to generate a new scaffold for a change to my Rails database, the new migration file is prepended by a datestamp (e.g. 200903140912_create_users.rb) instead of a sequence number (e.g. 004_create_users.rb). I then have to manually change the file name to fit in with the rest of the migration files. Does an...

I have been hacking with Ruby from time to time, but I haven't done anything big or multithreaded with it. I have heard that MRI only supports green threads and JRuby supports native threads via JVM. However, I stumble upon comments on blogs and discussion groups which say that "Rails is not thread-safe" or that Ruby itself is not thread...
I'm a little confused about when to use single quoted strings versus double quoted strings. I've noticed that if I put a variable inside a single quoted string, it doesn't get interpreted. Also, if I use a newline character in a double quoted string, it causes the string to be displayed over two lines whereas in a single quoted string th...

I would like to switch to Nokogiri's xpath search as this seems to support regex in search strings. How do I implement the (pseudo) css search mentioned below in an xpath search? require 'rubygems' requi...

In Ruby, methods with side effects or methods that change the object passed as parameters have "!" as a postfix. For example: "SomeString".gsub!(/S/, "s") would be changing the String object, while "SomeString".gsub(/S/, "s") would work on a copy of the String object, and would not change the state of any objects outside of the method...
