Trying out Hobo (with some hiccups)

So I tried Hobo for the first time today. I really like it. It will definitely help when I am creating things that need value added quickly. I look forward to using it more.

The documentation is a work in progress, but is already good enough to learn Hobo. With the release of Hobo 0.7.2 and Rails 2.0.2, some of the documentation is lagging, but if you are already versed in Ruby / Rails, you will figure it out quickly.

I wanted to fill everyone in on an issue I ran into. When I tried to create the Hobo application, it started to fail when creating the user model, which stopped the process, so many other things did not occur. It turns out that the default database on Rails 2.0.2 is SQLLite. I did not have the adapter installed which was the root of the problems. So you could install the adapter and fix the issues.

I opted to modify the hobo command file so it would accept the -d,—database switches that the rails command accepts. This will allow you to set you default database to whatever you like. Thus, the hobo command works again without installing SQLLite adapter.

Simply replace all the code in your hobo file with this code (if you are on Hobo 0.7.2). I found my file at: C:\ruby\lib\ruby\gems\1.8\gems\hobo-0.7.2\bin\hobo.

   puts "\n***Default database type is: #{default_db}...\n"
   system("rails -d #{default_db} #{app_path}")
else
   system("rails #{app_path}")
end


Dir.chdir(app_path) do
  gen = "ruby #{File.join('script', 'generate')}"
  plugin = "ruby #{File.join('script', 'plugin')}"

  FileUtils.touch("public/stylesheets/application.css")

  puts "\nInstalling classic_pagination\n"
  command(plugin, "install svn://errtheblog.com/svn/plugins/classic_pagination")
 
  if hobo_svn
    puts "\nInstalling Hobo plugin via svn checkout...\n"
    command("svn co #{HOBO_REPO} vendor/plugins/hobo")
  else
    puts "\nInstalling Hobo plugin...\n"
    FileUtils.cp_r hobo_src, "vendor/plugins/hobo"
  end

  puts "\nInitialising Hobo...\n" 
  command(gen, "hobo --add-routes")

  puts "\nInstalling Hobo Rapid and default theme...\n"
  command("#{gen} hobo_rapid --import-tags")

  if user_model
    puts "\nCreating #{user_model} model and controller...\n"
    command("#{gen} hobo_user_model #{user_model}")
    command("#{gen} hobo_user_controller #{user_model}")
  end
 
  puts "\nCreating standard pages...\n"
  command("#{gen} hobo_front_controller front --delete-index --add-routes")
 
  if create_db
    puts "\nCreating databases"
    command("rake db:create:all")
  end
end

If you need to change yours manually, I just added to the usage string, one case to the case statement to handle the new switches and an if statement to testing if a different default database was specified.

Enjoy!

    Thanks for this fix! So easy, yet so maddening when it wasn’t there.
