Defines an attribute as readonly. This will ensure that the value for the attribute is only set when the document is new or we are creating. In other cases, the field write will be ignored with the exception of remove_attribute and update_attribute, where an error will get raised.
@example Flag fields as readonly.
class Band include Mongoid::Document field :name, type: String field :genre, type: String attr_readonly :name, :genre end
@param [ Array<Symbol> ] names The names of the fields.
