      I'm not sure if this is somehow related to MONGOID-2218, but I'm trying to initialise a field's default value from an associated object, which is throwing a NoMethodError.

      I have something like the following:

      class User
  include Mongoid::Document
  has_many :blogs
  field :name
end

class Blog
  include Mongoid::Document
  belongs_to :user
  field :name, default: -> { "#{user.name}'s Blog" }
end

      When I attempt to build or create a new blog via the user association:

      [Development]>> user = User.create name: 'Ralph Hinkley'
[Development]>> user.blogs.create
NameError: undefined local variable or method `user' for #<Blog:0x007fa6de436548>
	from /Users/jnh/.rvm/gems/ruby-1.9.3-p327/gems/mongoid-3.0.13/lib/mongoid/attributes.rb:225:in `method_missing'
	from /Users/jnh/Dev/tmp/blog_test/app/models/blog.rb:4:in `block in <class:Blog>'

      However, creating it and passing in the associated user object works, ie:

      [Development]>> Blog.create(user: user)
