List dynamic attributes in a Mongoid Model

Question

I have gone over the documentation, and I can\'t find a specific way to go about this. I have already added some dynamic attributes to a model, and I would like to be able to it

Answer 1

So, what I ended up doing is this. I'm not sure if it's the best way to go about it, but it seems to give me the results I'm looking for.

class Order
  def dynamic_attributes
    self.attributes.delete_if { |attribute| 
      self.fields.keys.member? attribute 
    }
  end
end

Attributes appears to be a list of the actual attributes on the object, while fields appears to be a hash of the fields that were predefined. Couldn't exactly find that in the documentation, but I'm going with it for now unless someone else knows of a better way!
