中重定向和测试它时遇到问题

我在使用get方法时测试没有通过，但是当我使用put方法时，对于相同的代码库是绿色的。我不知道如何解决这个问题，需要帮助才能通过测试。

我收到200 HTTP状态代码，但我希望获得有关重定向的确认，以便rspec跟踪它。在尝试使用category_product_url(category, product)编辑产品时，基本上需要执行的操作是将非产品所有者的登录用户重定向到error: 'You are not allowed to edit this product.'并使用闪存get http method。

二手宝石rspec-rails，devise和decent_exposure。 Ruby 2.1.5和Rails 4.1.8

实际错误消息：

Failure/Error: expect(response).to redirect_to(category_product_url(category, product))
   Expected response to be a <redirect>, but was <200>

Failure/Error: expect(controller.flash[:error]).to eq 'You are not allowed to edit this product.'

   expected: "You are not allowed to edit this product."
        got: nil

   (compared using ==)

我的规格

context 'another user is singed in' do
let(:user) { create(:user) }
let(:user2) { build(:user) }
let(:product) { Product.create! valid_attributes }

before do
  sign_in user2
  controller.stub(:user_signed_in?).and_return(true)
  controller.stub(:current_user).and_return(user2)
  controller.stub(:authenticate_user!).and_return(user2)
  product.user = user
end

describe 'GET edit' do
  describe 'with valid params' do
    it 'redirects to product page' do
      get :edit, { id: product.to_param, category_id: category.to_param }
      expect(response).to redirect_to(category_product_url(category, product))

    end

    it 'renders error message' do
      get :edit, { id: product.to_param, category_id: category.to_param }
      expect(controller.flash[:error]).to eq 'You are not allowed to edit this product.'
    end
  end
end

我的控制器

before_action :authenticate_user!, only: [:new, :edit, :update, :destroy, :create]
expose(:category)
expose(:products)
expose(:product)

def edit
end

def update
  if product.user == current_user
    if self.product.update(product_params)
      redirect_to category_product_url(category, product), notice: 'Product was successfully updated.'
    else
      render action: 'edit'
    end
  else
     redirect_to category_product_url(category, product), flash: { error: 'You are not allowed to edit this product.' } 
  end
end

private
def product_params
  params.require(:product).permit(:title, :description, :price, :category_id, :user_id)
end

奇怪的是，put方法在使用相同的update操作时工作正常。以下规格正在传递

describe 'PUT update' do
  describe 'with valid params' do
    it 'redirects to product page' do
      put :update, { id: product.to_param, product: { 'title' => 'MyString' }, category_id: category.to_param }
      expect(response).to redirect_to(category_product_url(category, product))
    end

    it 'does not update product' do
      put :update, { id: product.to_param, product: { 'title' => 'MyNewString' }, category_id: category.to_param }
      expect(controller.product.title).to_not eq 'MyNewString'
    end

    it 'renders error message' do
      put :update, { id: product.to_param, product: { 'title' => 'MyString' }, category_id: category.to_param }
      expect(controller.flash[:error]).to eq 'You are not allowed to edit this product.'
    end
  end
end

Answer 1

decent_exposure和devise的工作方式，您需要先调用before_action方法，然后通过您选择的私有方法。

对于此特定示例，您的控制器应包含此

before_action :author!, only: [:edit, :update]

和私有方法过滤器

def author!
  unless self.product.user == current_user
    redirect_to category_product_url(category, product),
      flash: { error: 'You are not allowed to edit this product.' }
  end
end

通过这种方式，您可以获得get http requests和put http requests规范。

Answer 2

试试这个

expect(:get => "/products/1/edit").to route_to(:controller => "controller_name", :action => "action_name")

希望这会奏效。

预期的响应是<重定向>，但是<200>。使用get：edit </redirect>时
