我正在测试轨道引擎.这是我的装置：

# test/fixtures/seven_portfolio/items.yml
item_one:
  description: item one description
  finished_at: <%= 7.days.ago %>
  is_featured: true
  item_type: 0

item_two:
  description: item two description
  finished_at: <%= 6.days.ago %>
  is_featured: false
  item_type: 1


# test/fixtures/seven_gallery/galleries.yml
gallery_one:
  title: seven_gallery_gallery_one_title
  item: item_one

# test/fixtures/seven_gallery/photos.yml
photo_one:
  caption: photo_one_caption
  gallery: gallery_one

# test/fixtures/seven_portfolio/item_videos.yml
one:
  item: item_one

例如,当我删除item：item_one和类似的关联行.测试效果很好
