从另一个视图渲染一个视图

我有几个视图希望出现在渲染的每个视图上，但如果没有重复代码或违反规范，我似乎找不到实现此目的的方法。

这是我当前的代码，在每个视图中进行调用：

def ImOnABoat::Views
  def layout
    html do
      head do title "Petstore" end
      body do yield end
    end
  end

  def navigation
    p "Welcome to our tiny petstore!"
  end

  def poodle
    navigation  # Have to duplicate this in every view
    p "We have a poodle!"
  end

  def fluffy_bunny
    navigation  # Have to duplicate this in every view
    p "Come see-- OH CRAP IT'S A VELOCIRAPTOR!"
  end
end

我还可以通过允许公共块在主体之外渲染来使其工作，但这违反了规范，并且最终可能会严重破坏一些抓取脚本。

def layout
  def head do title "Petstore" end
  nav  # This is not inside <body>!
  def body do yield end
end

I have a couple of views I'd like to have appear on every view that is rendered, but short of duplicating code or breaking the specifications, I can't seem to find a way to accomplish this.

Here's my current code, putting calls in every view:

def ImOnABoat::Views
  def layout
    html do
      head do title "Petstore" end
      body do yield end
    end
  end

  def navigation
    p "Welcome to our tiny petstore!"
  end

  def poodle
    navigation  # Have to duplicate this in every view
    p "We have a poodle!"
  end

  def fluffy_bunny
    navigation  # Have to duplicate this in every view
    p "Come see-- OH CRAP IT'S A VELOCIRAPTOR!"
  end
end

I can also make it work by allowing the common blocks to render outside the body, but this is against specification and will probably end up horribly breaking some scraper scripts down the road.

def layout
  def head do title "Petstore" end
  nav  # This is not inside <body>!
  def body do yield end
end

这可以使用 Rails 布局并在布局中渲染部分来完成。减少这种“建设”的需要并使管理变得更加容易。

请记住，这是纯 Ruby，因此您只需在布局中调用 navigation 方法即可：

module ImOnABoat::Views
  def layout
    html do
      head { title "Petstore" }
      body do
        navigation
        yield
      end
    end
  end

  def navigation
    p "Welcome to our tiny petstore!"
  end

  def poodle
    p "We have a poodle!"
  end

  def fluffy_bunny
    p "Come see-- OH CRAP IT'S A VELOCIRAPTOR!"
  end
end

Remember that this is plain Ruby, so you can simply call the navigation method in the layout:

module ImOnABoat::Views
  def layout
    html do
      head { title "Petstore" }
      body do
        navigation
        yield
      end
    end
  end

  def navigation
    p "Welcome to our tiny petstore!"
  end

  def poodle
    p "We have a poodle!"
  end

  def fluffy_bunny
    p "Come see-- OH CRAP IT'S A VELOCIRAPTOR!"
  end
end
