Sinatra 中带有 HAML 模板功能的模板功能
原标题:Template functions with HAML in Sinatra

我希望能够在Sinatra HAML 模板中创建模板功能, 这些模板本身包含 haml 。 是否有办法做到这一点或类似的功能? 如果它也能加分的话, 很酷 。

< 强势 > foo.haml

def foo(x)
   %h2 something
   %p something about #{x}

%h1 Herp de derp
= foo("mary")
= foo("us")

干杯! 干杯! 干杯! 干杯!

问题回答

实际上,你可以做这样的事情:

# app.rb    

require  sinatra 
require  haml 
helpers do
  def foo(name)
    haml = <<-HAML
#hello_block
   Hello, #{name}
HAML
    engine = Haml::Engine.new(haml)
    engine.render
  end
end

get  /  do
  haml :index
end

# index.haml
= foo  World     

函数是近距离的, 您真正需要的就是所谓的“ 强度 > 部分 comment 部分

基本上,你最终会得到以下结果

# _foo.haml.erb
%h2 somthing
%p= x

# index.haml.erb
%h1 Herp de derp
= render :partial => "foo", :locals => { :x => "mary" }
= render :partial => "foo", :locals => { :x => "us" }
