如何在Ruby和ERB（不是Rails）中使用视图和布局？

How can I use views and layouts with Ruby and ERB (not Rails)?

今天我正在使用此代码来呈现视图：

Today i'm using this code to render my view:

def render(template_path, context = self)
 template = File.read(template_path)
 ERB.new(template).result(context.get_binding)
end

这很好，但是如何我实现了相同的功能，但是要在布局内渲染模板？我想调用render_with_layout（template_path，context = self），以便它具有默认布局。

This works very well, but how can I implement the same function, but to render the template inside a layout? I want to call render_with_layout(template_path, context = self), and so that it will have a default layout.

推荐答案

感谢所有答案！

我终于解决了通过这样做，我希望其他人也可以找到此代码有用：

I solved it finally by doing this, I hope someone else also can find this code useful:

def render_with_layout(template_path, context = self)
template = File.read(template_path)
render_layout do
  ERB.new(template).result(context.get_binding)
end
end

def render_layout
layout = File.read('views/layouts/app.html.erb')
ERB.new(layout).result(binding)
end

我这样称呼它：

def index
@books = Book.all
body = render_with_layout('views/books/index.html.erb')
[200, {}, [body]]
end

然后它将使用硬编码（到目前为止）布局呈现我的视图..

Then it will render my view, with the hardcoded (so far) layout..
