rake db:migration not working on travis-ci build

Question

I'm trying to build my Ruby on Rails project from github on Travis-CI, but I 'm running into a migration problem. It runs a rake task for migration, but it complains about the same migration step after that. It follows my .travis.yml file: ``` language: ruby rvm: - 1.9.2 before_script: - "rake db:migrate RAILS_ENV=test" ``` And here's the build output: ``` 1Using worker: ruby4.worker.travis-ci.org:travis-ruby-3 2 3 4 5$ cd ~/builds 6 7 8$ git clone --depth=100 --quiet git://github.com/rafaelportela/bacilo.git rafaelportela/bacilo 9 10 11 12$ cd rafaelportela/bacilo 13 14$ git checkout -qf 7553b7351b7a642e39ea7b55204de6cd4f320c36 15 16 17$ export TRAVIS_RUBY_VERSION=1.9.2 18 19$ rvm use 1.9.2 20Using /home/vagrant/.rvm/gems/ruby-1.9.2-p290 21 22$ ruby --version 23ruby 1.9.2p290 (2011-07-09 revision 32553) [i686-linux] 24 25$ gem --version 261.8.17 27 28 29$ export BUNDLE_GEMFILE=/home/vagrant/builds/rafaelportela/bacilo/Gemfile 30 31$ bundle install 32Fetching gem metadata from https:/…

Accepted Answer

This blog post helped me tremendously when I was trying to get my Rails 3.2 app working with Travis CI, and write a `.travis.yml` file that actually worked. Here's mine for your reference, so hope it helps:

.travis.yml

```
language: ruby
rvm:
  - 1.9.2
  - 1.9.3
env:
  - DB=sqlite
  - DB=mysql
  - DB=postgresql
script: 
  - RAILS_ENV=test bundle exec rake db:migrate --trace
  - bundle exec rake db:test:prepare
  - bundle exec rspec spec/
before_script:
  - mysql -e 'create database my_app_test'
  - psql -c 'create database my_app_test' -U postgres
bundler_args: --binstubs=./bundler_stubs
```
