Ruby on rails 如何测试文件上载和控制器？

我的看法

我的Rspec测试（不起作用）

错误：失败/错误：post:upload\u image，：upload=>@file，：car\u id=>@car.id 命名错误： #文件的未定义方法“[]”：/tmp/test-bus-1.jpg20120826-29027-plg28d

怎么了？

根据您设置表单的方式（因为您正在调用

params[：upload][：datafile]

），我认为您需要将rspec测试更改为：

before :each do
  @car = FactoryGirl.create(:car)
  @file = fixture_file_upload('/files/test-bus-1.jpg', 'image/jpg')

end

it "can upload a car" do
  post :upload_image, :upload => @file, :car_id => @car.id
  response.should redirect_to images_path(:car_id => @car.id)
end

---

我想，params[：upload][：datafile]中的问题。。。

  def upload_image   
    if params[:upload].present? && params[:car_id].present?
      DataFile.save_image_file(params[:upload][:datafile], params[:car_id]) # My methods to save image and other operations with file

    end
    redirect_to images_path(:car_id => params[:car_id])
  end

before :each do
  @car = FactoryGirl.create(:car)
  @file = fixture_file_upload('/files/test-bus-1.jpg', 'image/jpg')

end

it "can upload a car" do
  post :upload_image, :upload => @file, :car_id => @car.id
  response.should redirect_to images_path(:car_id => @car.id)
end

post :upload_image, :upload => { :datafile => @file }, :car_id => @car.id
