Hobo in Two Minutes

To build a Hobo 2.0 app you need to have a working Rails setup. If you can create a Rails app and have it connect to a database, you’re all set.

You need at least version 3.2.5 of Rails:

$ rails -v

Windows && OS X

First install Hobo.

$ gem install hobo

$ hobo -v

Now create an app! We’ve only got two minutes so we’ll create an ultra-useful Thing Manager.

$ hobo new thingybob --setup

(The --setup option tells hobo to use the defaults rather than asking questions about your application. After you play with Hobo a bit so that you understand the questions, you will probably want to omit the --setup)

Now skip the “Linux” section and move on to the “common” section.

Linux

First install Hobo.

$ gem install hobo

$ hobo -v

Now create an app! We’ve only got two minutes so we’ll create an ultra-useful Thing Manager.

$ hobo new thingybob

It will ask you Do you want to start the Setup Wizard now?. Answer “n”. We need to fix up the Rails Gemfile, and then we’ll start the Setup Wizard.

Using your editor of choice, edit the file Gemfile. There is a line that looks like this:

 # gem 'therubyracer', :platforms => :ruby

Remove the # from the beginning of the line to uncomment it. Then run:

 $ bundle
 $ hobo generate setup_wizard --wizard=false

(The --wizard=false option tells hobo to use the defaults rather than asking questions about your application. After you play with Hobo a bit so that you understand the questions, you will probably want to omit the --wizard=false)

Common

There will be lots of output produced as Hobo runs the rails command and runs the setup generator. This process may take a while, depending on your internet connection and computer speed.

$ cd thingybob
$ hobo g resource thing name:string body:text
$ hobo g migration

...Respond to the prompt with 'm'
...then press enter to chose the default filename

$ rails s

And browse to

http://localhost:3000

And there is your app! You should be able to

• Sign up
• Create and edit Things
• Search for things

That’s it. Why not try another of the tutorials on your left.
