Railsは初めてで、TDDを実行せずにアプリを作成しましたが、今は戻ってすべてのテストに合格しようとしています。私はそれらのほとんどを通過しましたが、私が理解できない同じ問題に関連するいくつかが残っています。アプリも正しく機能します。これらのテストに合格できません。
テストは失敗し、これを提供します:
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 "#<File:0x007fc6d17b28f8>"

# ./app/controllers/products_controller.rb:43:in `create'
# ./spec/controllers/products_controller_spec.rb:86:in `block (4 levels) in <top (required)>'
2) ProductsController POST create with valid params creates a new Product
Failure/Error: post :create, {:product => valid_attributes}, valid_session
Paperclip::AdapterRegistry::NoHandlerError:

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 "#<File:0x007fc6d36b3dd8>"

私のコントローラーの「create」メソッド:
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
私のモデル:
class Product < ActiveRecord::Base
attr_accessible :designed, :features, :photo, :manufactured, :name, :case_study
has_attached_file :photo, {
:styles => {
: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
私のテスト:
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
