創建HAML一個幫手或一些與在軌道上

Question

我使用HAML與我的Rails應用程序的紅寶石和我有一個問題是如何最簡單的方法插入此HAML代碼到一個HTML文件：

<div clas="holder"> 
<div class=top"></div> 
    <div class="content"> 
    Content into the div goes here 
    </div> 
<div class="bottom"></div> 
</div> 

我想在我這樣的哈姆文件中使用它：

%html 
%head 
%body 
    Maybee some content here. 
    %content_box #I want to get the code i wrote inserted here 
    Content that goes in the content_box like news or stuff 
%body 

有沒有更簡單的方法來做到這一點？

我得到這個錯誤：

**unexpected $end, expecting kEND** 

與此代碼：

# Methods added to this helper will be available to all templates in the application. 
module ApplicationHelper 
def content_box(&block) 
    open :div, :class => "holder" do # haml helper 
    open :div, :class => "top" 
    open :div, :class => "content" do 
     block.call 
    open :div, :class => "bottom" 
    end 
end 
end 

Answer 1

您可以使用haml_tag太

def content_box 
    haml_tag :div, :class => "holder" do 
    haml_tag :div, :class => "top" 
    haml_tag :div, :class => "content" do 
     yield 
    haml_tag :div, :class => "bottom" 
    end 
end 

和HAML

%html 
    %head 
    %body 
    Maybee some content here. 
    = content_box do 
     Content that goes in the content_box like news or stuff 

Answer 2

典型的解決方案是使用部分。

或者在你的_helper.rb文件中的helper方法：

def content_box(&block) 
    open :div, :class => "holder" do # haml helper 
    open :div, :class => "top" 
    open :div, :class => "content" do 
     block.call 
    end 
    open :div, :class => "bottom" 
    end 
end 

而且在HAML：

%html 
    %head 
    %body 
    Maybee some content here. 
    = content_box do 
     Content that goes in the content_box like news or stuff
