Question

我的观点

  <%= form_tag({:action => 'upload_image', :car_id => @car.id}, :multipart => true) do %>
    <label for="upload_file"><%= t('field.select_image') %></label>
    <%= file_field 'upload', 'datafile' %>&nbsp;<%= submit_tag t('field.upload_file') %>
  <% end %>

我的控制器

  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

我的Rspec测试（不起作用）

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

错误：失败/错误：发布：upload_image，：upload =＆gt; @file，：car_id =＆gt; @ car.id NoMethodError：未定义方法`[]'for #File：/tmp/test-bus-1.jpg20120826-29027-plg28d

怎么了？

Answer 1

在我看来，根据您设置表单的方式（因为您正在调用params[:upload][:datafile]），您需要将您的rspec测试更改为：

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

如何测试文件上传和控制器？
