Ruby＆Mongoid-未初始化的常量

Question

I'm getting "uninitialized constant SwimResult":

class LegResult
  include Mongoid::Document
  field :secs, type: Float
  embedded_in :entrant
  embeds_one :event, as: :parent
  validates_presence_of :event

  after_initialize do |doc|
    doc.calc_ave
  end


  def calc_ave

  end

  def secs=value  
    self[:secs] = value
    calc_ave

  end
end


class SwimResult < LegResult
  field :pace_100,  as: :pace_100, type: Float

  def calc_ave
  end
end



class BikeResult < LegResult
  field :mph,  as: :mph, type: Float

  def calc_ave
  end
end

I know it can occur when classes are in a separate files, but in my case they're all in one - class LegResult and two subclasses inheriting after it. I'll appreciate any help.

您需要将SwimResult和BikeResult类移至swim_result.rb和bike_result.rb之前，请确保要求输入“ leg_result”，这将确保文件以正确的顺序加载
