ruby-on-rails – 如何将Globalize翻译装置加载到测试模型？

我有一个Post模型,我运行Post.create_translation_table！ globalize提供的迁移,用于设置post_translations表.

现在我想自动加载夹具文件的翻译.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',626768522)

如果我执行逆操作会发生类似的错误(即post.tral中的post_translation：my_first_translation)

我如何获得魔法？
