ruby-on-rails - 如何加载 Globalize 翻译装置来测试模型？

Question

我在 Rails 4.1.12 中使用 gobalize gem 4.0.3。

我有一个 Post 模型，并且我运行了 Post.create_translation_table! 提供的 globalize 迁移来设置 post_translations 表。

现在我想从我的夹具文件中自动加载翻译。夹具支持 label references for associations 所以我有这个:

# spec/fixtures/posts.yml

my_first_post:
  author: dave

# spec/fixtures/post_translations.yml

my_first_post_translation:
  locale: en    
  title: My first post
  content: What a time to be alive!
  post: my_first_post

# spec/models/post_spec

require 'rails_helper'

RSpec.describe Post, type: :model do
  fixtures('post/translations', :posts, :authors)

  subject(:post) { posts(:my_first_post) }

  it "has an author" do
    expect(post.author).to eq(authors(:dave))
  end

  it "has a title" do
    binding.pry
    expect(post.title).to be_present
  end
end

但是运行 RSpec 会引发以下错误:

 Failure/Error: Unable to find matching line from backtrace
 ActiveRecord::StatementInvalid:
   SQLite3::SQLException: table post_translations has no column named post: INSERT INTO "post_translations" ("locale", "title", "content", "post", "created_at", "updated_at", "id") VALUES ('en', 'My first post', 'This is some compelling english content', 'my_first_post', '2015-08-21 10:23:27', '2015-08-21 10:23:27', 626768522)

如果我执行相反的操作(即 post_translation: my_first_translation 中的 posts.yml )，则会发生类似的错误

怎么找回魔法？

解决方案

将 fixtures/post_translations.yml 移动到 fixtures/post/translations.yml

my_first_translation 中关联的关键是 globalized_model

所以你最终会得到这个:

<!-- language: yml -->
# spec/fixtures/posts.yml

my_first_post:
  author: dave

# spec/fixtures/post/translations.yml

my_first_post_translation:
  locale: en
  title: My first post
  content: What a time to be alive!
  globalized_model: my_first_post

解释

翻译模型是 Post::Translation 。命名空间意味着 Post::Translation 固定装置的位置必须遵循与 app/models 中的模型相同的嵌套约定。

Post::Translation(以及任何 globalize 翻译模型)上的关联名称是 globalized_model 。 ActiveRecord::FixtureSet uses the association name to recognise the fixture key as an association 。
