ruby-on-rails – Rails – 测试夹具错误NoMethodError:未定义的方法`type’为nil:NilClass

前端之家收集整理的这篇文章主要介绍了ruby-on-rails – Rails – 测试夹具错误NoMethodError:未定义的方法`type’为nil:NilClass前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
运行测试时,我有一个问题,它使用模型之间的关联.

这是我得到的错误,一旦我运行rake测试:

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

项目类:

    has_one :item_video,class_name:'SevenPortfolio::ItemVideo',foreign_key: "seven_portfolio_item_id"
    has_one :item_gallery,class_name: 'SevenGallery::Gallery',foreign_key: "seven_portfolio_item_id"

    def type_content
      self.item_gallery if self.item_type == 0
      self.item_video if self.item_type == 1

和画廊类:

class SevenGallery::Gallery < ActiveRecord::Base
  include SevenGallery::Concerns::Gallery
  belongs_to :item,:class_name => 'SevenPortfolio::Item'
end

这是schema.rb文件

ActiveRecord::Schema.define(version: 20150414145951) do

    t.string   "title",limit: 255

    t.integer  "seven_portfolio_item_id",limit: 4
  end

  add_index "seven_gallery_galleries",["seven_portfolio_item_id"],name: "index_seven_gallery_galleries_on_seven_portfolio_item_id",using: :btree

  add_foreign_key "seven_portfolio_item_videos",on_delete: :cascade
end

解决方法

在我的开发环境中迁移和回滚几次后,我遇到了相同的错误.这与“_type”列有关.

唯一为我修复的是测试数据库删除/创建:

bundle exec rake db:reset RAILS_ENV=test

在做这个之前,请确信你的schema.rb状况良好.
