Question

我正在使用桌上足球测井应用程序。

我的模特遵循以下方案：游戏 - ＆gt;团队 - ＆gt;位置 - ＆gt;目标

在目标中我有一个after_save，它将检查两支球队是否进球10个。如果一个团队有，那么它设置一个胜利者（团队）并设置Game.completed_at。

此功能似乎通过用户测试在实践中拯救了胜利者和Game.completed_at，但是在我的Rspec测试中，在一个团队达到10个目标后，我看到在Goal中调用了after_save回调，但在测试中回调之后如果这些列都没有保存。我不确定发生了什么。

class Goal < ActiveRecord::Base
  after_save :complete_game
    def complete_game

      game = self.position.team.game
      isGameComplete = false

      game.teams.each do |team|
        if team.get_goals_total == 10
            team.winner = true
            team.save!
            puts "complete_game: team.winner: #{team.winner}"

            game.completed_at = DateTime.now
            game.save!

            isGameComplete = true
      end
    end
    puts "complete_game: game.completed_at: #{game.completed_at}"
  end

Rspec测试：

it "sets a winner after ten goals" do 
  @blue_team.positions.first.goals.create
  @blue_team.positions.first.goals.create
  @blue_team.positions.first.goals.create
  @blue_team.positions.first.goals.create
  @blue_team.positions.first.goals.create
  @blue_team.positions.first.goals.create
  @blue_team.positions.first.goals.create
  @blue_team.positions.first.goals.create
  @blue_team.positions.first.goals.create
  @blue_team.positions.first.goals.create

  puts "winner: #{@blue_team.winner}"
  puts "completed_at: '#{@game.completed_at}'"

  expect(@blue_team.winner).to be true
end

Rspec输出：

complete_game: game.completed_at:
complete_game: game.completed_at:
complete_game: game.completed_at:
complete_game: game.completed_at:
complete_game: game.completed_at:
complete_game: game.completed_at:
complete_game: game.completed_at:
complete_game: game.completed_at:
complete_game: game.completed_at:
complete_game: team.winner: true
complete_game: game.completed_at: 02/20/2015 12:44 PM
TEST OUTPUT: winner: false
TEST OUTPUT: completed_at: ''
    sets a winner after ten goals (FAILED - 1)

查看日志后，after_save设置了winner / completed_at，但在回调之外的＆＃39; TEST OUTPUT＆＃39;然后没有设置winner / completed_at。

rspec测试中的回调是否不会保留after_save回调中的更改？在生产中工作，似乎不会保存测试中的变化。

收到以下回答，询问有关reddit.com/r/rails（http://www.reddit.com/r/rails/comments/2wlhrf/how_to_testing_before_save_callbacks/）的问题

在Team模型上执行回调后，需要相应对象的 .reload 。

测试按预期通过。

it "sets a winner after ten goals" do

  10.times do
    @blue_team.positions.first.goals.create
  end

  expect(@blue_team.reload.winner).to be true
end

Answer 2

您需要stub回调操作：

@blue_team.stub(:complete_game).and_return(true)

在rspec测试期间，ActiveRecord保存在after_save回调中不会持久存在
