Question

对不起我的英文，

我的模型验证

validates_uniqueness_of :price, scope: [:brand, :establishment, :presentation, :user], conditions: -> { where(created_at: Date.today.beginning_of_day..Date.today.end_of_day) }

这是我的工厂并测试它。

FactoryGirl.define do
  factory :price do
    association :establishment
    association :presentation
    association :brand
    association :user
    price 9.99
  end
end

it "is invalid on duplicated by date" do
  price = create(:price)
  expect(build(:price, price.attributes)).to have(1).errors
end

我正在......

1) Price is invalid on duplicated by date
    Failure/Error: expect(build(:price, price.attributes)).to have(1).errors
      expected 1 errors, got 0

为什么吗

Answer 1

仅当您在对象上调用valid?时，验证错误才会添加到新对象（未保存）

it "is invalid on duplicated by date" do
  price = create(:price)
  new_price = build(:price, price.attributes)
  new_price.valid?
  expect(new_price).to have(1).errors
end

Answer 2

我解决了，我的错误是在数据库概念上，我有一个浮动类型的价格字段，我把它改为十进制类型来修复错误。

带条件的validates_uniqueness_of未按预期工作
