Instance Method Details

#content_for(key, &block) ⇒ Object

Capture a block of content to be rendered later. For example:

<% content_for :head do %>
  <script type="text/javascript" src="/foo.js"></script>
<% end %>

You can call content_for multiple times with the same key (in the example :head), and when you render the blocks for that key all of them will be rendered, in the same order you captured them.

def content_for(key, &block)
  content_blocks[key.to_sym] << begin
    if respond_to?(:block_is_haml?) && block_is_haml?(block)
      capture_haml(&block)
    else
      block.call
    end
  end
end

#yield_content(key) ⇒ Object

Render the captured blocks for a given key. For example:

<head>
  <title>Example</title>
  <% yield_content :head %>
</head>

Would render everything you declared with content_for :head before closing the <head> tag.
