How do I add left and right classes to every other element in a loop in Ruby on Rails? - ruby-on-rails

Question

I am working within a Ruby on Rails app. I have a loop that creates divs like this:
<% #snorks.each do |snork| -%>
<div>
<%= snork %>
</div>
<% end %>
And I need the output to have every other div be floated left or right like this:
<div class="left">
Allstar Seaworthy
</div>
<div class="right">
Casey Kelp
</div>
<div class="left">
Dimmy Finster
</div>
<div class="right">
Daffney Gillfin
</div>
<div class="left">
Tooter Shellby
</div>
<div class="right">
Dr. / Uncle Galeo
</div>
Additionally, I need to add a div with class="clear" every two divs, like this:
<div class="left">
Allstar Seaworthy
</div>
<div class="right">
Casey Kelp
</div>
<div class="clear"></div>
<div class="left">
Dimmy Finster
</div>
<div class="right">
Daffney Gillfin
</div>
<div class="clear"></div>
<div class="left">
Tooter Shellby
</div>
<div class="right">
Dr. / Uncle Galeo
</div>
<div class="clear"></div>
I have researched, and found a few posts saying that the alternate classes can be accomplished easily by using cycle(), and that does work. However, when I use it in two places within the loop it stops working right and just outputs something like this:
<div class="left">
Allstar Seaworthy
</div>
<div class="left">
Casey Kelp
</div>
<div class="left">
Dimmy Finster
</div>
<div class="left">
Daffney Gillfin
</div>
<div class="left">
Tooter Shellby
</div>
<div class="left">
Dr. / Uncle Galeo
</div>
What's the best practices way in Ruby on Rails to alternate classes in a loop, and also add something every other loop?

Answer 1

According to the documentation, if you need nested ones you name them. Otherwise they will both share the name "default" and conflict.
<% #snorks.each do |snork| -%>
<div class="<%= cycle('left', 'right') -%>">
<%= snork %>
</div>
<%= cycle('','<div class="clear"></div>', :name=>"cleardiv") %>
<% end %>

Answer 2

The best thing here seems to be using each with index. That way you could do some simple modulus math to determine if the number is odd or even and output the correct class and add the clears.
#snorks.each_with_index do | snork, index|
If index%2 == 0
class = 'left'
else
class = 'right'
end
Well u get my drift and I'm on my phone.

Answer 3

use cycle helper
http://apidock.com/rails/ActionView/Helpers/TextHelper/cycle
<% #snorks.each do |snork| -%>
<div class="<%= cycle("left", "right") -%>">
<%= snork %>
</div>
<% end %>
Edit: for adding new div; following could help
<% #snorks.each_slice(2) do |snork_batch| -%>
<% snork_batch.each do |snork|%>
<div class="<%= cycle("left", "right",:name=>"className") -%>">
<%= snork %>
</div>
<%end%>
<div class="clear"></div>
<% reset_cycle("className")%>
<% end %>
