Question

我刚刚从Rails 4.1上的2.8.0升级到了shoulda-matchers 3.1.2，现在我的验证唯一性作用于测试失败并显示此消息;

  1) Invoice should validate that :invoice_no is case-sensitively unique within the scope of :ledger_id
     Failure/Error: it { is_expected.to validate_uniqueness_of(:invoice_no).scoped_to(:ledger_id)}

       Invoice did not properly validate that :invoice_no is case-sensitively
       unique within the scope of :ledger_id.
         :ledger_id does not seem to be an attribute on Invoice.
     # ./spec/models/invoice_spec.rb:6:in `block (2 levels) in <top (required)>'

这是我的测试

require 'rails_helper'

RSpec.describe Invoice, :type => :model do
  it { is_expected.to validate_uniqueness_of(:invoice_no).scoped_to(:ledger_id)}
  it { is_expected.to validate_presence_of(:ledger_id)}

测试是否存在：ledger_id传递。

这是我的模特

  validates :ledger_id, presence: true
  validates_uniqueness_of :invoice_no, scope: :ledger_id, case_sensitive: false

解决方案（我仍在使用机械师）

  subject { Invoice.make!(ledger: Ledger.make!) }
  it { is_expected.to validate_uniqueness_of(:invoice_no).case_insensitive.scoped_to(:ledger_id)}

我认为您的问题是thoughtbot/shoulda-matchers

试试这个：

require 'rails_helper'

RSpec.describe Invoice, :type => :model do
 is_expected = expect(create(:invoice))
 it { is_expected.to 
 validate_uniqueness_of(:invoice_no).case_insensitive.scoped_to(:ledger_id)}
 it { is_expected.to validate_presence_of(:ledger_id)}

shoulda-matchers属性似乎不是模型的属性
