有什么方法可以避免在不创建新文件的情况下进行haml代码重复? [英] Any way to avoid haml code duplication without creating new file?

问题描述

我在Sinatra应用程序的.haml模板文件中包含以下代码:

I have the following code in a .haml template file in a Sinatra app:

- if(@order == 'inverse') 
    - @list.reverse_each do |item| 
        .item
            %span.action-move(data-icon="o")
            .detail.title=item[0]
            .detail.content=item[1]
            %span.action-delete(data-icon="d")
- else 
    - @list.each do |item| 
        .item
            %span.action-move(data-icon="o")
            .detail.title=item[0]
            .detail.content=item[1]
            %span.action-delete(data-icon="d")

如您所见，5行代码是相同的.有没有一种方法可以重构此代码，以免在这里不重复创建一个额外的文件以用作部分文件?

As you can see, 5 lines of code are identical. Is there a way that I can refactor this code to avoid the duplication here without creating an additional file to use as a partial?

推荐答案

离我远去-您可以创建一个临时列表，该模板将在条件语句中设置，然后像这样循环遍历该临时列表:

Off the top of my head - you could create a temp list that you would set in the conditionals and then loop through the temp list like so:

- if(@order == 'inverse')
  - temp = @list.reverse
- else 
  - temp = @list
- @temp.each do |item| 
  .item
    %span.action-move(data-icon="o")
    .detail.title=item[0]
    .detail.content=item[1]
    %span.action-delete(data-icon="d")
