Partials in Coffee HAML (.hamlc)

问题:

I am using backbone.js on a rails backend with HAML Coffee, which is compiled by haml_coffee_assets. There is some duplication in my templates.

Is there a way to create rails-like partials to dry up my templates?

Addition: Can I do content_for(:something) in Coffee HAML?

回答1:

There is no content_for helper in Haml Coffee, but you simply can render another template within a template.

Without Local Variables

For example, you've a template test:

%p My Partial
%ul
  %li Is included

You can include it within another template like this:

%p Another template
!= JST['test']()
%p That includes a partial

The trick is to unescape the rendered HTML with !=.

With Local Variables

To pass local variables, just send them to the JST function. If this is your partial (articles/_comments.jst.hamlc):

%h2=@title
%p=@content

Then this may be your template:

%h1 Comments for this article
- for comment in @article.comments 
  != JST['articles/_comment'](comment)
