Your scope cannot be called 'locked'

• see: http://github.com/rails/rails/issues/7421

• see: http://github.com/rails/rails/pull/6985

  class Article < ActiveRecord::Base
    scope :locked, where(...
  end
  

will cause intermittent problems of the type

undefined method 'locked' for #<Class:0x007fdab3025298>

Use something like ‘access_locked’ instead

Be careful with name of attribute writer

If restricting access to attributes you normally get code like

attr_accessible :foo,  

When using these nested attributes you end up with code like

attr_accessible :foo, :bar_attributes

Its very easy to leave of the _attributes suffix e.g

attr_accessible :foo, :bar

which will cause you all sorts of problems
