Ruby on rails Rails：属于Rails引擎，并且在Rails引擎中有许多关联

因此，我使用Rails 6构建了一个应用程序。我已经使用Rails引擎实现了应用程序的一些核心功能

引擎的名称是Baseblog，我有两个模型，分别称为Author和Post

一个

作者

有许多

帖子

，而

帖子

属于一个

作者

。以下是我的模型实现：

作者模型：

module Baseblog
  class Author < ApplicationRecord
    has_many :posts, dependent: :destroy

    validates :name, presence: true
    validates :address, presence: true
  end
end

module Baseblog
  class Post < ApplicationRecord
    belongs_to :author

    validates :name, presence: true
  end
end

作者工厂Bot

FactoryBot.define do
  factory :school do
    name { "MyString" }
    address { "MyText" }
  end
end

帖子架构

create_table "baseblog_posts", force: :cascade do |t|
  t.string "name"
  t.text "description"
  t.bigint "baseblog_author_id", null: false
  t.datetime "created_at", precision: 6, null: false
  t.datetime "updated_at", precision: 6, null: false
  t.index ["baseblog_author_id"], name: "index_baseblog_posts_on_baseblog_author_id"
  end

但是，当我为作者模型运行测试时，我得到了错误：

Failures:

  1) Baseblog::Author associations is expected to have many posts
     Failure/Error: it { is_expected.to have_many(:posts) }
       Expected Baseblog::Author to have a has_many association called posts (Baseblog::Post does not have a author_id foreign key.)
     # ./spec/models/baseblog/author_spec.rb:6:in `block (3 levels) in <module:Baseblog>'

工厂Bot用于后期规范

require 'rails_helper'

module Baseblog
  RSpec.describe Author, type: :model do
    describe 'associations' do
      it { is_expected.to have_many(:posts) }
    end

    describe "validations" do
      it { is_expected.to validate_presence_of(:name) }
      it { is_expected.to validate_presence_of(:address) }
    end
  end
end

FactoryBot.define do
  factory :post do
    name { "MyString" }

    association :author
  end
end

但是，当我为Post运行规范测试时，我得到以下错误：

Failures:

  1) Baseblog::Post associations is expected to belong to author required: true
     Failure/Error: it { is_expected.to belong_to(:author) }
     
     NoMethodError:
       undefined method `author_id' for #<Baseblog::Post:0x000056397e47dc50>
       Did you mean?  author
                      author=
     # ./spec/models/baseblog/post_spec.rb:6:in `block (3 levels) in <module:Baseblog>'

Baseblog::Post validations is expected to validate that :author_id cannot be empty/falsy
     Failure/Error: it { is_expected.to validate_presence_of(:author_id) }
     
     Shoulda::Matchers::ActiveModel::AllowValueMatcher::AttributeDoesNotExistError:
       The matcher attempted to set :author_id on the Baseblog::Post to
       nil, but that attribute does not exist.
     # ./spec/models/baseblog/post_spec.rb:19:in `block (3 levels) in <module:Baseblog>'

故障：
1） Baseblog:：文章关联应属于作者必需：true
失败/错误：它{应该属于（：作者）}
命名错误：
未定义的方法“author\u id”#
你是说？作者
作者=
#./spec/models/baseblog/post_spec.rb:6:in'block（3层）in'
Baseblog:：Post验证应验证以下内容：author_id不能为空/falsy
失败/错误：应为{验证是否存在（：author\u id）}
Shoulda:：Matchers:：ActiveModel:：AllowValueMatcher:：AttributeDesNotexistError:
匹配器试图将Baseblog:：Post上的：author_id设置为
nil，但该属性不存在。
#./spec/models/baseblog/post_spec.rb:19:in'block（3层）in'

你能试试这个吗

modulebaseblog
类作者<应用程序记录
有很多：帖子，类名：'Baseblog:：Post'，外键：：Baseblog\u author\u id，依赖：：destroy
验证：名称，状态：true
验证：地址，状态：true
结束
结束

modulebaseblog
类Post

Baseblog:：Post中是否有作者id？是的。我只是把它添加到问题中，这对我很有效。非常感谢你。我想这里需要注意的是，Author模型和Post模型的

外键

是相同的。是的，我也有同样的问题，我这样做是因为rails可能必须为模块中的模型指定类名和外键。也许您可以找到更好的解决方案我在测试时遇到了一些其他问题，并且我已经更新了问题@dedypuji，您可以提供帮助吗？如果您直接使用id分配，请使用baseblog\u author\u id，而不是使用author\u id；如果您使用baseblog:：author实例，则可以使用author关联进行分配

describe 'validations' do
  it { is_expected.to validate_presence_of(:name) }
  it { is_expected.to validate_presence_of(:author_id) }
end

FactoryBot.define do
  factory :post do
    name { "MyString" }

    association :author
  end
end
