Question

我正试图在独立（不是rails）应用程序中执行类似的操作：

layout.slim：

h1 Hello
.content
  = yield

show.slim：

= object.name
= object.description

我无法弄清楚如何指定布局和模板。苗条（或haml）可能吗？感谢。

Answer 1

layout.slim文件如下所示：

h1 Hello
.content
  == yield

contents.slim文件如下所示：

= name

这可以缩短，但为了便于说明，我将其分为各个步骤。

require 'slim'

# Simple class to represent an environment
class Env
  attr_accessor :name
end

# Intialize it
env = Env.new
# Set the variable we reference in contents.slim
env.name = "test this layout"

# Read the layout file in as a string
layout = File.open("layout.slim", "rb").read

# Read the contents file in as a string
contents = File.open("contents.slim", "rb").read

# Create new template object with the layout
l = Slim::Template.new { layout }

# Render the contents passing in the environment: env
# so that it can resolve: = name
c = Slim::Template.new { contents }.render(env)

# Render the layout passing it the rendered contents
# as the block. This is what yield in layout.slim will get
puts l.render{ c }

这将输出：

<h1>Hello</h1><div class="content">test this layout</div>

使用slim或haml在独立（非rails）ruby应用程序中指定布局和模板
