Deploying a Hobo app to Heroku
December 28th, 2009
Hobo and Heroku make for a killer combination for getting your app built and deployed in record time.
These instructions are for Hobo 0.9.102. If you’re using an older version the steps may differ.
$ hobo myapp $ cd myapp $ git init $ heroku create yourappname
Create a .gems file, since Hobo isn’t pre-installed on Heroku:
hobo --version 0.9.102
It is recommend to specify a particular version of any gem you use, in case a future release isn’t fully backwards compatible. (There’s no longer any need to specify will_paginate here.)
Next, create a .gitignore file:
log/* db/*.sqlite3
Generate the database migrations:
$ script/generate hobo_migration
Choose [m] to migrate now and give it a name such as create users.
To generate the auto dryml files in app/views/taglibs/auto/, you’ll need to access the site once locally. Hobo cannot create these on Heroku because the filesystem is read-only. So run:
$ script/server
And open http://localhost:3000 in your browser.
You can then add all your files into the git repository, and push them to Heroku:
$ git add * $ git add .gems $ git add .gitignore $ git commit -m "initial import" $ git push heroku master
It will take a couple of minutes to install the Hobo gem the first time you deploy, but subsequent deployments will be faster.
Next, run the database migration on Heroku:
$ heroku rake db:migrate
If you don’t see any error message, then you should be good to go:
$ heroku open
Common Problems
If you see the Rails “something went wrong” error, use heroku console to view the error log.
- “relation “users” does not exist” – you probably forgot to run heroku rake db:migrate

thanks for this Andy – I found this while trying to fix my previously working hobo/heroku installation.
running through your steps now leads me to an app which doesn’t start … which looks increasingly like a heroku issue to me :(
App failed to start
You need to explicitly specify your Rails version on your Gemfile or .gems file.
Read the docs on managing gems for more information. Original Error
Missing the Rails 2.3.5 gem. Please `gem install -v=2.3.5 rails`, update your RAILS_GEM_VERSION setting in config/environment.rb for the Rails version you do have install

@Paul
I haven’t tried it, but this may be the solution:
