Rails get index of "each" loop [duplicate]
So I have this loop:
<% @images.each do |page| %>
<% end %>
How would I get the index of "page" inside of the loop?
<% @images.each_with_index do |page, index| %>
<% end %>
The two answers are good. And I also suggest you a similar method:
<% @images.each.with_index do |page, index| %>
<% end %>
You might not see the difference between this and the accepted answer. Let me direct your eyes to these method calls: .each.with_index see how it's .each and then .with_index.
Try each_with_index.
