Conditional Top Level Tags HAML w/o using partials

Question

What is an elegant way to conditionally add a higher level html element without repeating the inner contents? How can this be achieved without using partials (all content in one file)?

For example, say I have this content and I want to wrap all the content in a div based on some condition so the (img, 'some code' x 3) is not being repeated.

- unless p.product_url.nil?
  #myDiv
    %img{src: img_url}
    some code
    some code
    some code
- else
  %img{src: img_url}
  some code
  some code
  some code

Answer 1

- content_for :inner_contents do
  %img{src: img_url}
  some code
  some code
  some code

- unless p.product_url.nil?
  #myDiv
    = yield :inner_contents
- else
  = yield :inner_contents
