Limerick Rake is a collection of useful rake tasks for Rails apps. Some we wrote ourselves, many we’ve collected from others in the community. We’re always on the lookout for helpful rake tasks so if you have anything, please post them in the comments. To use in a Rails app:

script/plugin install git://github.com/thoughtbot/limerick_rake.git

Database

Read tasks/database.rake for details for configuration. Load initial database fixtures (in db/bootstrap/*.yml) into the current environment’s database. Load specific fixtures using FIXTURES=x,y:

rake db:bootstrap:load

Prints a list of unindexed foreign keys so you can index them:

rake db:indexes:missing

Run model validations on all model records in database:

rake db:validate_models

Git

Merge a branch into the origin/staging branch:

rake git:push:staging

Merge the staging branch into origin/production for launch:

rake git:push:production

Show the difference between current branch and origin/staging:

rake git:diff:staging

Show the difference between origin/staging and origin/production:

rake git:diff:production

Pull updates from suspenders, the thoughtbot rails template:

rake git:pull:suspenders

Branch origin/production into BRANCH locally:

rake git:branch:production

Backup

Backup the current database. Timestamped file is created as :rails_root/../db-name-timestamp.sql:

rake backup:db

Backup all assets under public/system. File is created as :rails_root/../system.tgz:

rake backup:assets

Haml & Sass

Convert all CSS files in public/stylesheets to Sass:

rake sass:all_css2sass

rake sass:all_sass2css
