问题
AS the guides, the command used to prepare test database is
bundle exec rake db:test:prepare
However, I have found that following command also works & created the test db for me.
bundle exec rake test:prepare
Wanted to know if this is a valid command, if yes. Where can I find the documentation.
tested on rails 3.2.8
回答1:
According to github and the source code task 'test:prepare' => 'db:test:prepare' is mentioned at the bottom.
Hence it's a shortcut, wrapper, whatever you want to call it. Another question would be why this doesn't up when you do bundle exec rake -T but hey.
