带Shoulda和多个范围的Rails Uniques未通过测试

shoulda rspec-rails ruby-on-rails

我在这里做错什么了?我很确定实际的代码是正确的,但是我的测试有问题,这只是一个失败的shoulda matchers?还是我错过了什么?

require 'rails_helper'

RSpec.describe Game, type: :model do
  subject { create :game }

  it { should belong_to(:home_team).class_name('Team') }
  it { should belong_to(:away_team).class_name('Team') }

  it { should validate_uniqueness_of(:start_date).scoped_to(:home_team_id) }
  it { should validate_uniqueness_of(:start_date).scoped_to(:away_team_id) }
end

class Game < ActiveRecord::Base
  belongs_to :home_team, class_name: 'Team'
  belongs_to :away_team, class_name: 'Team'

  validates_uniqueness_of :start_date, scope: :home_team_id
  validates_uniqueness_of :start_date, scope: :away_team_id
end

   Expected Game to validate that :start_date is case-sensitively unique
   within the scope of :home_team_id, but this could not be proved.
     Given an existing Game whose :start_date is â¹Fri, 31 Aug 2018 05:24:25
     UTC +00:00âº, after making a new Game and setting its :start_date to
     â¹Fri, 31 Aug 2018 05:24:25 UTC +00:00âº as well and its :home_team_id
     to a different value, â¹5âº, the matcher expected the new Game to be
     valid, but it was invalid instead, producing these validation errors:

     * start_date: ["has already been taken"]

对不起,我以前的回答不正确。看起来Shoulda不能自动处理你的案子。它改变 home_team_id 希望游戏是有效的,但它还是一样的 away_team_id ,因此您需要手动验证它

it 'validates uniqueness for both teams' do
  team1 = create :team
  team2 = create :team
  team3 = create :team
  game = create :game, home_team: team1, away_team: team2
  game1 = build :game, home_team: team1, away_team: team3
  game2 = build :game, home_team: team3, away_team: team2
  game3 = build :game, home_team: team2, away_team: team1

  expect(game).to be_valid
  expect(game1).not_to be_valid
  expect(game2).not_to be_valid
  expect(game3).to be_valid
end
