Ruby on rails rspec将重复块转换为方法

我的规范文件中有这个上下文

  context 'get :index' do 
            it 'should be loaded successfully if current user is not customer' do
              sign_in @creative
              get :index
              response.should be_success 
            end
            it 'should redirect to root page if current user is customer' do 
              sign_in @customer
              get :index
              response.should redirect_to root_path
            end
          end

context 'post :create' do 
            it 'should be loaded successfully if current user is not customer' do
              sign_in @creative
              post :create
              response.should be_success 
            end
            it 'should redirect to root page if current user is customer' do 
              sign_in @customer
              post :create
              response.should redirect_to root_path
            end
          end

我在两个不同的上下文中重复相同的代码。我像这样转换它，但它不起作用

def check_user_sign_in(request_type, action)
      context '#{request_type} :#{action}' do 
        it 'should be loaded successfully if current user is not customer' do
          sign_in @creative
          request_type action
          response.should be_success 
        end
        it 'should redirect to root page if current user is customer' do 
          sign_in @customer
          request_type action
          response.should redirect_to root_path
        end
      end
    end

  end

这里的问题是我没有使用参数作为方法名

你知道如何在干法中使用它吗？

这个：

context '#{request_type} :#{action}' do 

将不起作用，因为字符串插值未在单引号内计算

您必须使用双引号：

a = 'alpha' #=> "alpha"
b = 'beta'  #=> "beta"

'#{a} #{b}' #=> "\#{a} \#{b}"

"#{a} #{b}" #=> "alpha beta"

谢谢。这对于上下文来说是正确的，但是使用参数作为像请求类型动作这样的方法怎么样。
