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
