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 强 >
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!

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 强度” 。 这些是预定义的模板, 您可以在其他视图中放置。 例如, 您可能拥有一个“ EM> comment 部分 内容” 来显示评论作者、 时间戳、 内容等 。 然后您可以对特定文章的每个注释做此部分 。
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" }
