Question

我正在构建一个运行民意调查的Rails（4.1.0）应用程序。每次投票都有n与n席位的比赛。这是我的模特：

class Matchup < ActiveRecord::Base
  has_many :seats, dependent: :destroy

  def winning_seat
    seats.sort { |a,b| a.number_of_votes <=> b.number_of_votes }.last
  end
end

class Seat < ActiveRecord::Base
  belongs_to :matchup

  validates :matchup, presence: true
  validates :number_of_votes, presence: true

  def declare_as_winner
    self.is_winner = true
    self.save
  end

end

我对Matchup和Seat的规格没有问题。在民意调查结束时，我需要显示获胜者。我正在使用Sidekiq工作来处理民意调查的结束。它做了很多事情，但这里有相关的代码：

class EndOfPollWorker
  include Sidekiq::Worker

def perform(poll_id)
  poll = Poll.where(:id poll_id)
  poll.matchups.each do |matchup|
    # grab the winning seat
    winning_seat = matchup.winning_seat
    # declare it as a winner
    winning_seat.declare_as_winner
  end
end
end

这名工人的规格没有通过：

require 'rails_helper'

describe 'EndOfPollWorker' do
  before do
    #this simple creates a matchup for each poll question and seat for every entry in the matchup
    @poll = Poll.build_poll  
  end

  context 'when the poll ends' do
    before do
      @winners = @poll.matchups.map { |matchup| matchup.seats.first }
      @losers = @poll.matchups.map { |matchup| matchup.seats.last }
      @winners.each do |seat|
        seat.number_of_votes = 1
      end

      @poll.save!

      @job = EndOfPollWorker.new
    end

    it 'it updates the winner of each matchup' do
      @job.perform(@poll.id)
      @winners.each do |seat|
        expect(seat.is_winner?).to be(true)
      end
    end

    it 'it does not update the loser of each matchup' do
      @job.perform(@poll.id)
      @losers.each do |seat|
        expect(seat.is_winner?).to be(false)
      end
    end

  end

  end
end
end

当我运行此规范时，我得到：

EndOfPollWorker when poll ends it updates the winner of each matchup
     Failure/Error: expect(seat.is_winner?).to be(true)

       expected true
            got false

我对Seat和Matchup模型的规格传递得很好。我删除了很多测试代码，请原谅任何不匹配的标签，假设不是问题！

此外，当工作人员实际在开发模式下运行时，seat.is_winner属性实际上并未更新。

Sidekiq与您的问题无关。您直接调用perform，因此问题出在rspec和activerecord上。例如，将代码从perform方法中拉出并直接放入规范中，它仍然应该失败。

我怀疑这些实例是陈旧的，需要从数据库中重新加载#adload以获取#perform中所做的更改。

Rails模型规格传递，Sidekiq规范失败
