Missing host to link to!

So I was outputting URL from a rails model with


but my specs were complaining with

Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true

after some googling and trial and errors I found that this line would did the trick. Put it in your test_helper or spec_helper

Rails.application.routes.default_url_options[:host] = 'localhost:3000'

cheers :D

Rails 3, unit test, and autotest

This is just a reminder for myself, I finally can run autotest with this setup on my mac:

Gemfile content:

snip ...
group :development, :test do
  gem 'webrat'
  gem 'mocha'
  gem 'ZenTest'
  gem 'autotest-rails'
  gem 'autotest-growl'
  gem 'autotest-fsevent'

RAILS_ROOT/.autotest (create one if it doesn’t exist) content:

require "ZenTest"
require "autotest/rails"
require "autotest/growl"
require "autotest/fsevent"
Autotest.add_hook :initialize do |autotest|
  %w{.git .svn .hg .DS_Store ._* vendor tmp log doc config .rvmrc Gemfile .autotest README Rakefile}.each do |exception|

then go to your RAILS_ROOT directory, run bundle exec autotest, and watch those nice green growl pops up :D

RailsInstaller with ruby 1.9.2

UPDATE: RailsInstaller 2 has been released. It include ruby 1.9.2 and rails 3.1, read it here and download it here.

Railsinstaller from railsinstaller.org ships with ruby 1.8.7 by default, but if you want to use ruby 1.9.2, these steps might help you out.

  1. Download and install railsinstaller (default to C:\RailsInstaller, lets call this ROOT_DIR)
  2. Download and install Ruby 1.9.2 from rubyinstaller.org (railsinstaller only compatible with ruby from rubyinstaller.org) to ROOT_DIR\ruby192
  3. Edit file setup_environment.bat on ROOT_DIR\ruby1.8.7 (you can use notepad or notepad++)
  4. On line 12 in setup_environment.bat, change it to: SET RUBY_DIR=C:\RailsInstaller\Ruby192
  5. On line 27 change the line to: SET PATH=%RUBY_DIR%\bin;%RUBY_DIR%lib\ruby\gems\1.9.1\bin;%ROOT_DIR%\DevKit\bin;%ROOT_DIR%\Git\cmd;%PATH%
  6. Save the file
  7. Open railsinstaller console from Start menu and make sure the loaded ruby version is 1.9.2 by running ‘ruby -v’ command on the console
  8. Still on the console, go to devkit folder on ROOT_DIR\DevKit by running ‘cd C:\RailsInstaller\DevKit’ command
  9. Inside the devkit folder run ‘ruby dk.rb init’
  10. Still inside the devkit folder, run the ‘ruby dk.rb install –force’ command (note the 2 dash before force)
  11. If nothing went wrong then you should be able to install the various ruby gems that’s available out there (Ex. gem install rails).
  12. You need to install rails gem again (and any gems that you want to use) because the default rails gem that come with railsinstaller is on the ruby 1.8.7 folder while now you’ll be using the gems in the ruby192 folder.

And that’s it, now you can enjoy railsinstaller with ruby 1.9.2 :D

Problem with paperclip 2.3.4

I just upgrade my rails application to rails 2.3.10 because of this post, my application is using paperclip and by that time it was using paperclip 2.3.4, and on rails 2.3.9 everything is going well. But as soon as I upgraded to rails 2.3.10 when I run ./script/server I got this error:

=> Booting Mongrel
=> Rails 2.3.10 application starting on
/Library/Ruby/Gems/1.8/gems/activesupport-2.3.10/lib/active_support/dependencies.rb:466:in `load_missing_constant': 
uninitialized constant Paperclip::Glue (NameError)

After googling a while, none of the results was involving rails 2.3.10, but most of the answers suggesting to install paperclip version, so I think I’ll give it a try. So I change the line in my Gemfile to gem ‘paperclip’, ‘~>’, and then I run bundle install, after that I try to run ./script/server, and it run!

Missing the Rails 2.3.8 gem after bundle install, solved

Ok, basically I have just clone this rails 2.3.8 app which use bundler, and it told me to do “bundle install”, so I did, and it run without any problem, so far so good. After ‘bundle install’ finished successfully I try to run ‘rake db:create’ and it throws this error message :

Missing the Rails 2.3.8 gem. Please `gem install -v=2.3.8 rails`, update your RAILS_GEM_VERSION setting in config/environment.rb for the Rails version you do have installed, or comment out RAILS_GEM_VERSION to use the latest version installed.

I said, WTF? I do have rails 2.3.8 installed, in fact I’ve been using it for a while without any problem, so why is this new app cannot find it? google to the rescue! I found this post from heroku that explain the problem, and one of the solution is to add the Rails 2.3.8 gem to your gem manifest or Gemfile, so I did. Put this in your Gemfile just after the line that says ‘source :rubygems’

source :rubygems
gem 'rails', '2.3.8'

After that I try to run ‘rake db:create’ again, and it works! that’s another trick in my rails arsenal :)

Tudulis with Ruby on Rails

Tudulis which originally written with PHP and CakePHP is now have its clone. Meet rtudulis, just like tudulis it’s a web-based, free, todo list and tasks management application and most importantly it is written with Ruby on Rails instead, how cool is that? :D

The reasons behind why I created rtudulis are mainly to get to know about rails application deployment process (using capistrano). With the creation of this rails app I have to deal with capistrano and its several deployment strategies which I don’t have any experience before. And just like tudulis, the source code for rtudulis is available on my github repository in case anybody want to use it. Currently it doesn’t have all the feature of tudulis (PDF creation and twitter login) since it’s still under development, but if you want to try out the live application, you can go to http://r.tudulis.com and try it out.

Well, that’s all for now, happy forking! :D
