Rails 控制器内 json 对象中不存在 4 个集成测试数组

Question

我正在尝试为创建名为 books 的记录创建集成测试。我在测试中创建哈希时遇到问题。这是我的代码：

test/integration/creating_book_test.rb

require 'test_helper'

class CreatingBookTest < ActionDispatch::IntegrationTest

  def setup
    @michael_lewis = Author.create!(name: 'Michael Lewis')
    @business = Genre.create!(name: 'Business')
    @sports = Genre.create!(name: 'Sports')
    @analytics = Genre.create!(name: 'Analytics')

  end

  test "book is created successfully" do
    post '/api/books', { book: book_attributes }.to_json, {
      'Accept' => 'application/json',
      'Content-Type' => 'application/json'
    }
    ... assertions...
  end

  def book_attributes
    {title: 'Moneyball',
     year: 2003,
     review: 'Lorem Ipsum',
     rating: 5,
     amazon_id: '10832u13kjag',
     author_ids: [@michael_lewis.id],
     genre_ids: [@business.id, @sports.id, @analytics.id]
    }
  end

end

在控制器中，我将参数列入白名单：

  def book_params
    params.require(:book).permit(:title, :year, :review, :rating, :amazon_id, :author_ids, :genre_ids)
  end

问题是我在控制器中没有收到 :author_ids 和 :genre_ids。似乎数组没有发送到控制器，所以我无法测试关联是否正常工作。

谢谢。

你强参数声明错误。这是修复：

params.require(:book).permit(:title, :year, :review, :rating, :amazon_id, author_ids: [], genre_ids: [])

来自 Permitted Scalar Values 文档：

..To declare that the value in params must be an array of permitted scalar values map the key to an empty array.
