如何使用Carrierwave + FactoryGirl测试上传

Question

我想为我的应用程序创建一些测试,我有以下错误:

1) User feeds ordering should order feeds by id desc
     Failure/Error: @post_1 = FactoryGirl.create(:post)
     ActiveRecord::AssociationTypeMismatch:
       Attachment(#87413420) expected, got Rack::Test::UploadedFile(#81956820)
     # ./spec/models/user_spec.rb:37:in `block (3 levels) in <top (required)>'

这个错误是因为我的factories.rb文件中有这个

  factory :post do
    title "Lorem Ipsum"
    description "Some random text goes here"
    price "500000"
    model "S 403"
    makes "Toyota"
    prefecture "Aichi-ken"
    contact_info "ryu ryusaki"
    year "2012"
    shaken_validation "dec/2014"
    attachments [ Rack::Test::UploadedFile.new(Rails.root.join("spec/fixtures/files/example.jpg"), "image/jpeg") ]
    #attachments [ File.open(Rails.root.join("spec/fixtures/files/example.jpg")) ]
  end

测试期望一个Attachment对象,但我正在创建一个Rack::Test::UploadedFile对象.我该如何解决这个错误？

谢谢.

祝好运!

更新:

所以这就是我一步一步将文件上传到我的factories.rb.

A.因为我使用rspec,我在spec /和spec/fixtures /下创建了一个目录图像,然后在那里放了一个example.jpg图像,这样路径就是Rails.root/spec/fixtures/images /example.jpg

B.接下来,在我的workers.rb中,我改变了我的定义如下:

Factory.define :image do |image|
  image.image  fixture_file_upload( Rails.root + 'spec/fixtures/images/example.jpg', "image/jpg")
  image.caption           "Some random caption"
end

(可选:如果在rspec中重新启动spork服务器)

C.现在应该工作正常.

如果您有更多问题,请告诉我.我会尽力帮助:)

这是我发现做我需要的方式.

factory :attachment do
  file { fixture_file_upload(Rails.root.join(*%w[spec fixtures files example.jpg]), 'image/jpg') }
end

factory :post do
  title "Lorem Ipsum"
  description "Some random text goes here"
  price "500000"
  model "S 403"
  makes "Toyota"
  prefecture "Aichi-ken"
  status 'active'
  attachments { [ FactoryGirl.create(:attachment) ] }
end
