# In this case, the association chain would be:

# So you would just have to call find(:all) at the end of association
# chain. And this is what happened.

# In singleton controllers:

# class ManagersController < InheritedResources::Base
# belongs_to :project, :singleton => true
# end
#
# The association chain will be:
#
# Project.find(params[:project_id])
#
# So we have to call manager on it. And again, this is what happens.
