我正在構建一個運行輪詢的Rails(4.1.0)應用程序。每次投票都有n
與n
對位。這裏是我的車型:Rails模型規格傳遞,Sidekiq規格失敗
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
我的規格爲匹配和座位通過沒有問題。在投票結束時,我需要顯示獲勝者。我正在使用Sidekiq工作人員來處理投票結束。它做很多事情,但這裏的問題代碼:
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
這個工人的規範不及格:
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
當我運行這個天賦,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
我對Seat和Matchup車型的規格通過的很好。我將很多測試代碼都剪掉了,所以請原諒任何不匹配的標籤,假設這不是問題!
另外,當工作人員實際在開發模式下運行時,其實並未實際更新seats.is_winner屬性。
謝謝
Sidekiq woker只接受字符串參數,你確定你可以傳遞一個實例給那個woker嗎?你是否開始任何派對? – dddd1919 2014-10-09 01:46:28
你是對的!我錯誤地複製了。我會更新代碼。我試圖簡化,但我介紹了一個錯誤。我認爲@ job.perform會啓動worker,對吧? – panzhuli 2014-10-09 01:59:11
'@ job.perform'只是發送一個工作到sidekiq隊列,那麼你需要像[bundle exec sidekiq](http://sidekiq.org/)那樣在命令中啓動一個sidekiq worker,那麼這個工作將被執行。工作人員需要幾秒鐘才能完成,所以你可以「睡覺」等待它。 – dddd1919 2014-10-09 02:08:52
