如何創建早該宏

Question

上下文較小的代碼示例再次問這個問題：

# this is a dummy shoulda macro that creates a context 
    def self.macro_context 
    context "macro" do 
     yield 
    end 
    end 

    # i am expecting this test to fail within the macro context 
    context "some context" do 
    macro_context do 
     should "test" do 
     fail 
     end 
    end 
    end 

那麼我希望是看到：

1) Error: 
    test: some context macro context should test. (TestClassName) 

但我只得到了這一點：

那麼我希望是看到：

1) Error: 
    test: some context should test. (TestClassName) 

任何想法我做錯了什麼？

Answer 1

感謝舊金山的代碼，來解決這個問題，你不能只是產生新的上下文內的塊，你必須使用早該的merge_block方法。然後它應該看起來像這樣：

def self.macro_context(&block) 
    context "macro" do 
     merge_block(&block) 
    end 
    end

我的代碼中有類似的東西。我做了這樣的成test/shoulda_macros/whatever_file.rb

def self.should_require_login(actions = [:index], &block) 
if (actions.is_a? Symbol) 
    actions = [actions] 
end 
context "without user" do 
    actions.each do |action| 
    should "redirect #{action.to_s} away" do 
     get action 
     assert_redirected_to login_path 
    end 
    end 
end 
if block_given? 
    context "active user logged in" do 
    setup do 
     @user = Factory.create(:user) 
     @user.register! 
     @user.activate! 
     login_as(@user) 
    end 

    merge_block(&block) 
    end 
end 
end
