Question

I have the following task:

task :migrate_test => :environment do
   puts 'Running database migrations ...'
   puts `heroku run rake db:migrate --app my-app`
end

When I run heroku run rake db:migrate --app my-app in the console, the migration proceeds successfully. However, when I run rake migrate_test, I receive the following error:

Running database migrations ...

I believe it has something to do with rake running task in a different process that can't find the path, but haven't been able to find out how to tackle.

Was it helpful?

Solution 2

The solution was to upgrade the Heroku toolbelt. I still received an error /Users/Will/.rvm/gems/ruby-1.9.3-p194@global/bin/rake: No such file or directory but I guess the toolbelt is smart enough to compensate. The most recent toolbelt can be found here: https://toolbelt.heroku.com/

I would also suggest using exec ... as opposed to puts ... in the rake task since you'll be able to see the progress in realtime.

OTHER TIPS

Nothing's wrong with your code. See this issue on GitHub.

Just update rubygems and RVM. Or even better: use rbenv!
