问题 Quick problem description The value of the id in a nested form is rendered as 10006.0 instead of 10006 (decimal/float instead of an integer) resulting in an ActiveRecord::RecordNotFound exception. What is causing this behaviour?? The code setup So I followed the rails-guides tutorial on how to build nested forms.

问题 I'm running logstash like it saids in the starting page: java -jar logstash-1.2.1-flatjar.jar agent --config logstash-dev.conf With logstash-dev.conf like this: input { file { path => ["/tmp/catalina.jsonevent.log"] codec => json { charset => "UTF-8" } } } output { # Use stdout in debug mode again to see what logstash makes of the event. stdout { debug => true } elasticsearch_http { host => "127.0.0.1" } } And it jumps with this error: Exception in thread "LogStash::Runner" org.jruby

问题 I've deployed a new server that has the exact same version of JRuby (1.7.22), Java (openjdk-7-jre-headless 7u51), and bundler as the other servers. Both servers are running Ubuntu 14.04, but the new one has some newer packages. I deployed the same version of the project using Capistrano to the new server. When Capistrano runs bundle (or when I do it myself), the following error and callstack are presented: TypeError: can't convert Regexp into String end_with? at org/jruby/RubyString.java:5281

问题 I am using Rails 3.1.3, JRuby 1.7.6, and Warbler 1.3.8 Note This was not happening when using JRuby 1.6.7 - but we recently tried to update the JRuby version, and that is when this issue started. We use Warbler to package our ruby on rails application into a WAR file. That process pre-compiles all the assets and everything works fine (seems to work fine, the command is successful) We then deploy the WAR file with our Software (which uses a JRuby environment - 1.7.6 - and uses Jetty as a web

问题 Although I've often come here for solutions, however this is my first post!

问题 Problem I'm trying to produce some unicode characters after compiling my *.scss file. As an example, I have the following (SCSS): .element:after { content: "\a0"; } When the file is compiled, it outputs the following (CSS): .element:after { content: "\\a0"; } Notice the extra unwanted backslash (\). Attempted Solution #1 I did try the solution here: Sass: unicode escape is not preserved in .css file, which suggests introducing the following function: @function unicode($str) { @return unquote(

问题 On Windows 7 machine, I have installed jruby 1.6.7 and then installed pik with 'gem install pik'. I then ran pik_install C:\bin which installed pik properly. I can run "pik ls" command properly.

问题 I'm pretty new to the whole JRuby world. I'm using RSpec on a pretty big test suite. I'd like to be able to run the specs frequently but the JVM takes so long to startup it's becoming a real time drain. Is there a way to keep the JVM running? or a way to get specs to run faster with JRuby? 回答1: There are two things you could look into: Run a nailgun server and send spec runs to it. jruby --ng-server & and then jruby --ng -S spec or jruby --ng -S rake Use spork. http://www.ruby-forum.com/topic

问题 I used jruby-1.7.0 and testing frame work Test::Unit::TestCase. Now I have updated some gems which caused me to use MiniTest::Test for testing, so I also upgraded to jruby-1.7.13. I have a rake task too which builds my gems with java *.class files instead of ruby *.rb files. Now many things dont work any more like 'rake test', or require "my_gem_xyz" from irb, getting errors like load error and ArrayIndexOutOfBoudsException. I have rvm installed to switch between rubies. How can I use *.class
