Reload only one attribute mongoid

Question

I have model object implementing Mongoid::Document

model has an attribute called name

I need to reload only name of model

Is there something shorter than

Model.only(:name).find(model.id).name

like model.reload(:name)

Answer 1

Only rewrite the reload method:

module Mongoid
  module Document
    def reload(field = nil)
      field.nil? ? super() : eval("#{self.class.name}.only(:#{field}).find('#{self.id}').#{field}")
    end
  end
end
