HAML generate nested divs in loop - haml

Question

Is there any way to generate many divs nested each other?
I expect print some like this:
<div>
<div>
<div>
<div>
<div>
</div>
</div>
</div>
</div>
</div>
Simple loop is not helping
- (1..5).each do |i|
%div
Goes to
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>

There isn't any way of doing this in pure haml, by design.
Firstly, ask yourself: Do you really need this? There are often far better ways to achieve the result you want.
In my case, I needed an arbitrary nesting of divs with a particular class, based on a number I was given externally. I added the following to my rails helpers:
def nestify(css_class, level, &block)
if level > 0
content_tag(:div, class: css_class) { nestify(css_class, level - 1, &block) }
else
yield
""
end
end
Then, in your haml, you use it with a block:
= nestify('each-div-has-this-class', 5) do
Content for inner div.
[Edit] Quick note: I wrote this a while back, can't remember why - but this code is not production ready. Ruby doesn't work well with recursive functions. Please flatten it into a loop for better performance / scalability.
