无法弄清楚是什么导致我的测试失败
我是rails的新手，我在没有做TDD的情况下构建了一个应用程序，但我现在回去试图通过所有测试。 我已经通过了他们中的大多数，但还有一些与我无法弄清楚的相同问题有关。 该应用程序也正常运行，我只是无法通过这些测试。
测试失败并提供：
1) ProductsController POST create with valid params assigns a newly created product as @product Failure/Error: post :create, {:product => valid_attributes}, valid_session Paperclip::AdapterRegistry::NoHandlerError: No handler found for "#" # ./app/controllers/products_controller.rb:43:in `new' # ./app/controllers/products_controller.rb:43:in `create' # ./spec/controllers/products_controller_spec.rb:86:in `block (4 levels) in ' 2) ProductsController POST create with valid params creates a new Product Failure/Error: post :create, {:product => valid_attributes}, valid_session Paperclip::AdapterRegistry::NoHandlerError: No handler found for "#" # ./app/controllers/products_controller.rb:43:in `new' # ./app/controllers/products_controller.rb:43:in `create' # ./spec/controllers/products_controller_spec.rb:81:in `block (5 levels) in ' # ./spec/controllers/products_controller_spec.rb:80:in `block (4 levels) in ' 3) ProductsController POST create with valid params redirects to the created product Failure/Error: post :create, {:product => valid_attributes}, valid_session Paperclip::AdapterRegistry::NoHandlerError: No handler found for "#" # ./app/controllers/products_controller.rb:43:in `new' # ./app/controllers/products_controller.rb:43:in `create' # ./spec/controllers/products_controller_spec.rb:92:in `block (4 levels) in ' 我的控制器中的“创建”方法：
def create @product = Product.new(params[:product]) respond_to do |format| if @product.save format.html { redirect_to admin_path, notice: 'Product was successfully created.' } format.json { render json: @product, status: :created, location: @product } else format.html { render action: "new" } format.json { render json: @product.errors, status: :unprocessable_entity } end end end
我的型号：
class Product { :thumb => "x50>", :small => "x150>", :detail => "x600>" } }.merge(PAPERCLIP_STORAGE_OPTIONS) validates_attachment_presence :photo validates_attachment_size :photo, :less_than => 5.megabytes validates_attachment_content_type :photo, :content_type => ['image/jpeg', 'image/png'] end
我的测试：
before(:each) do @image = File.new(Rails.root + 'spec/fixtures/images/test.png') end def valid_attributes { "photo" => @image } end describe "POST create" do describe "with valid params" do it "creates a new Product" do expect { post :create, {:product => valid_attributes}, valid_session }.to change(Product, :count).by(1) end it "assigns a newly created product as @product" do post :create, {:product => valid_attributes}, valid_session assigns(:product).should be_a(Product) assigns(:product).should be_persisted end it "redirects to the created product" do post :create, {:product => valid_attributes}, valid_session response.should redirect_to(admin_path) end end end
如果您使用的是Rails 3.2，请尝试在测试中发送UploadedFile而不是File 。 UploadedFile在其初始化程序中采用文件名和内容类型。
before(:each) do @image = Rack::Test::UploadedFile.new(Rails.root.join('spec/fixtures/images/test.png'), 'image/png') end
您可能必须在测试或测试助手中包含Rack::Test::Methods 。
您还可以使用fixture_file_upload作为Rack::Test::UploadedFile.new的快捷方式，如下所示：
post :create, product: { photo: fixture_file_upload('spec/fixtures/images/test.png', 'image/png') }
您是否已将Paperclip附件添加到数据库中 – 例如创建和运行迁移？ 包括测试数据库？
