ruby-on-rails - 将方法添加到 Rails 中的模型时出现未定义的方法错误

Question

我有错误

未定义的方法 events_and_repeat' for #<Class:0x429c840>
app/controllers/events_controller.rb:11:in `index'

我的应用程序/模型/event.rb 是

class Event < ActiveRecord::Base
  belongs_to :user

  validates :title, :presence => true,
                    :length => { :minimum => 5 }
  validates :shedule, :presence => true

  require 'ice_cube'
  include IceCube

  def events_and_repeats(date)
    @events = self.where(shedule:date.beginning_of_month..date.end_of_month)

    return @events
  end

end

应用程序/ Controller /events_controller.rb

def index
    @date = params[:month] ? Date.parse(params[:month]) : Date.today
    @repeats = Event.events_and_repeats(@date)

    respond_to do |format|
      format.html # index.html.erb
      format.json { render json: @events }
    end
  end

怎么了？

就像斯沃兹说的，你在一个类上调用了一个实例方法。重命名:

def self.events_and_repeats(date)

我只是在回答中写这个，因为评论太长了，
查看 ice-cube github 页面，它严格地说:

Include IceCube inside and at the top of your ActiveRecord model file to use the IceCube classes easily.

我也认为你不需要 require在你的模型中。
