rspec的+ carrierwave：圖像不會產生

Question

我有這個天賦：

post :create, :room_id => @room.id, :image => Rack::Test::UploadedFile.new(path, 'text/jpg') 
response.should redirect_to admin_room_path(@room) 

@room.reload.pictures.count.should == 1 
pic = @room.pictures.first 

File.open(pic.image.url).should == File.open(path) 
# Not working 

它失敗，出現以下錯誤：

1) Admin::PicturesController should fail to upload a new picture 
    Failure/Error: File.open(pic.image.url).should == File.open(path) 
    Errno::ENOENT: 
     No such file or directory - /uploads/picture/image/5134d0fa93ff007fcd000016/image1.jpg 
    # ./spec/controllers/admin/pictures_controller_spec.rb:26:in `initialize' 
    # ./spec/controllers/admin/pictures_controller_spec.rb:26:in `open' 
    # ./spec/controllers/admin/pictures_controller_spec.rb:26:in `block (2 levels) in <top (required)>' 

該文件沒有找到，但是，創建目錄/uploads/picture/image/5134d0fa93ff007fcd000016/ 。

除文件外的所有內容都是正確的。

我的初始化：

if Rails.env.test? or Rails.env.cucumber? 
    CarrierWave.configure do |config| 
    config.storage = :file 
    config.enable_processing = true 
    end 
end 

我缺少的東西？

Answer 1

pic.image.url是一個沒有主機的URL路徑。

嘗試：

File.open(File.join(Rails.root, "public", pic.image.url)).should == File.open(path) 

或者，我的偏愛，讓carrierwave處理它：

File.open(pic.image.path).should == File.open(path) 

或比較內容：

pic.image.read.should == File.open(path).read
