Question

我有以下代码：

工厂/ web.rb

FactoryGirl.define do
  factory :web do
    name 'Name of web'
    url 'http://google.es'

    after(:create) do |web|
      10.times do |i|
        web.link << FactoryGirl.create(:link, web: web, url: i, _id: i)
      end
    end
  end
end

工厂/ link.rb

factory :link do
  anchor_text 'anchor'
  title 'title'
  code 200
  sequence :url do |n|
    "http://google.es/#{n}"
  end
end

模型/ web.rb

class Web
  include Mongoid::Document
  (...)
  has_many :link
end

模型/ link.rb

class Link
  include Mongoid::Document
  field :_id, type: String, default: ->{ Digest::MD5.hexdigest(url) }
  belongs_to :web
  field :url, type: String
  (...)
end

所以我在Link中有一个自定义ID，它在开发环境中工作但是当我运行rspec时，我正在进行所有测试：

Failure/Error: Unable to find matching line from backtrace
TypeError:
can't convert nil into String
# ./app/models/link.rb:4:in `digest'
# ./app/models/link.rb:4:in `hexdigest'
# ./app/models/link.rb:4:in `block in <class:Link>'

你可以尝试写：

factory :link do
  sequence(:url) { |n| "http://google.es/#{n}" }

  anchor_text 'anchor'
  title 'title'
  code 200
  url
end

具有自定义ID和factoryGirl的Mongoid
