Rails minitest 在 has_many 验证中失败

Question

我有如下简单的 belongs_to/has_many 关系：

class AppropriatenessTestResult < ApplicationRecord
  belongs_to :appropriateness_test_question
end

class AppropriatenessTestQuestion < ApplicationRecord
  has_many :appropriateness_test_results, dependent: :destroy
end

AppropriatenessTestResult 迁移：

class CreateAppropriatenessTestResults < ActiveRecord::Migration[6.1]
  def change
    create_table :appropriateness_test_results do |t|
      t.references :appropriateness_test_question, foreign_key: true, index: { name: 'idx_appropriateness_test_question_id' }

      t.timestamps
    end
  end
end

现在我想测试一下关系是否设置正确。为此，我为 AppropriatenessTestQuestion 模型编写了 Minitest：

require 'test_helper'

class AppropriatenessTestQuestionTest < ActiveSupport::TestCase
  context 'associations' do
    should have_many(:appropriateness_test_question)
  end
end

这给了我一个错误：

Failure: AppropriatenessTestQuestionTest#test_: associations should have many appropriateness_test_question. Expected AppropriatenessTestQuestion to have a has_many association called appropriateness_test_question (no association called appropriateness_test_question)

我错过了什么？

Answer 1

should have_many(:appropriateness_test_questions)

has_many协会使用复数，祝你好运！

Answer 2

已修复！我不小心检查了 appropriateness_test_questions 而不是 appropriateness_test_results

的关联

应该是：

should have_many(:appropriateness_test_results)

而不是：

should have_many(:appropriateness_test_questions)
