rake db:migrate fails due to undefined method symlink' for class Capistrano::Configuration::Namespaces::Namespace'

[kevindew]

I got this when I updated my version of webistrano and tried to migrate. To verify it wasn't a customisation of my fork I also tried doing a fresh clone, bundle install and tried to migrate and got the same error.

Quick work around to migrate without error is to just remove undef :symlink from config/initializers/capistrano_namespace_rake_fix.rb but naturally that must have been added for a reason.

Stack trace:

RAILS_ENV=production rake db:migrate --trace
rake/rdoctask is deprecated. Use rdoc/task instead (in RDoc 2.4.2+)

I seem to get this problem starting the app as well.

It worked for me by removing config/initializers/capistrano_namespace_rake_fix.rb. Looks like this fix is not necessary anymore.
