Upgrade from 1.2 to 1.5 fails

[digitaria]

We have experienced an issue upgrading from 1.2 to 1.5. The code was checked out on a new server,
the database was dumped and loaded on the new server. The migrations were run. All dependencies are installed.

Webistrano runs, but when you go to deploy, the following is output to the web interface "Log":

*** is not a class/module
*** /var/www/deploy/webistrano/app/models/project.rb:31:in `tasks'
*** /var/www/deploy/webistrano/vendor/rails/activerecord/lib/active_record/associations/association_proxy.rb:217:in `send'

*** /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
*** script/runner:3

The server logs have nothing. This is the only helpful output we can gather.

By the way, we're running the most recent code:

git remote show origin * remote origin
* remote origin
  Fetch URL: http://github.com/peritor/webistrano.git
  Push  URL: http://github.com/peritor/webistrano.git

With Rails 2.3.5 and ruby 1.8.7 on Ubuntu.

I would check that all your templates are available on the new server :)
Project.all.collect(&:template).uniq - ProjectConfiguration.templates.keys

That was it. Thank you.
