如何使用Carrierwave + FactoryGirl测试上传 [英] How to test upload with Carrierwave + FactoryGirl

问题描述

我想为我的应用创建一些测试，但出现以下错误:

I want to create some tests for my app and I have the following error:

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)>'

此错误是因为我的factories.rb文件中有此错误

This error is because I have this on my factories.rb file

  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

测试期望使用Attachment对象，但是我正在创建Rack::Test::UploadedFile对象.我该如何解决这个错误?

The test expect an Attachment object but I m creating an Rack::Test::UploadedFile object. How can I solve this error?

谢谢.

更新:

这就是我逐步完成的将文件上传到我的factory.rb中的操作.

So here is what I did step by step to upload a file into my factories.rb.

A.由于我使用rspec，因此我在spec/下创建了目录装置，并在spec/fixtures/下创建了目录图像，然后在其中放置了example.jpg图像，因此路径为Rails.root/spec/fixtures/images/example .jpg

A. Since I use rspec, I created a directory fixtures under spec/ and a directory images under spec/fixtures/, and then put an example.jpg image in there, such that the path was Rails.root/spec/fixtures/images/example.jpg

B.接下来，在我的factory.rb文件中，我的定义如下:

B. Next, in my factories.rb, I changed my definition as followed:

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，则重新启动您的spork服务器)

(optional: restart your spork server if in rspec)

C.现在应该可以正常工作.

C. Should work fine now.
