ruby-on-rails – 如何使用Draper 0.14.0访问装饰器规范文件中的

require 'spec_helper'

describe ProductDecorator do
  let(:product) { FactoryGirl.create(:product) }

  subject do
    ProductDecorator.first
  end

  before do
    product
  end

  it 'should render the name attribute with a link to the product page' do
    subject.name.should == h.link_to(product.name,'test')
  end
end

当我运行我的规范时,我得到以下内容：

F.....

Failures:

  1) ProductDecorator should render the name attribute with a link to the product page
     Failure/Error: subject.name.should == h.link_to(product.name,'resr')
      NameError:
       undefined local variable or method `h' for #<RSpec::Core::ExampleGroup::Nested_2:0x007fbbf212c8b0>
     # ./spec/decorators/product_decorator_spec.rb:15:in `block (2 levels) in <top (required)>'

Finished in 0.98531 seconds
6 examples,1 failure

Failed examples:

rspec ./spec/decorators/product_decorator_spec.rb:14 # ProductDecorator should render the name attribute with a link to the product page

根据文档,装饰器文件夹中的规范应该可以访问辅助方法,但是我的规范没有.我也试过手动标记我的规格,但似乎没有任何影响.

谢谢你的期待.
