Rails:是否可以使用HAML语法编写视图助手? [英] Rails: Is it possible to write view helpers with HAML syntax?

问题描述

在重构期间，仅复制一部分HAML模板并将其粘贴到帮助者的代码中将非常方便.当前在这种情况下1)我必须从头开始重写那部分视图2)我必须使用冗长的语法，例如content_tag或haml_tag.

During refactoring it would be quite handy just to copy part of HAML template and paste it to helper's code. Currently in such cases 1) I have to rewrite that part of view from scratch 2) I have to use that verbose syntax like content_tag or haml_tag.

我知道有可能使用HAML systax定义充当帮助程序的局部.尽管1)对我来说，为每个小小的微型函数创建一个单独的文件是不方便的，但2)局部的调用语法非常冗长.

I know that it's possible to define partials with HAML systax that will serve as helper. Though 1) as for me it's inconvinient to create a separate file for each small tiny function 2) invocation syntax for partial is quite verbose.

理想情况下，我希望我的* _helper类看起来像这样:

Ideally i'd like my *_helper class to look like this:

- def some_helper(*its_args)
  .some_class
    = some_ruby_expression
  %some_tag#some_id
    - another_expression do
      etc

或至少像这样:

define_haml_helper :some_helper, [:arg1, :arg2], %{
  .some_class
    = some_ruby_expression
  %some_tag#some_id
    - another_expression do
      etc
}

有没有可以解决我问题的插件?

Is there a plugin that solves my issue?

或者，也许您可​​以描述如何将HAML代码段重构为可重用的元素(帮助程序/函数/部分/构建器/等)?

Alternatively, maybe you can describe how do you refactor HAML snippets to reusable elements (helpers/functions/partials/builders/etc)?

推荐答案

来自参考:

def render_haml(code)
    engine = Haml::Engine.new(code)
    engine.render
end

这将启动一个新的Haml引擎并进行渲染.

This initiates a new Haml engine and renders it.
