Do..end loop just returning main array - arrays

Question

Can anyone help me to find problem here?
#deals.each.with_index(1) do |deal, i|
binding.pry
puts "#{deal.title} - #{deal.price} - Rating: #{deal.deal_rating}"
# puts "Available for #{deal.price}"
# puts "Rating: #{deal.deal_rating}"
# puts "#{deal.title}"
# puts "Available at "
end
If I do binding.pry, and try to check the value of deal here, it is returning me complete #deals array rather than one deal.
Thank you so much in advance for your help.

Use just each_with_index which will give you the object and the index inside the total of elements being iterated:
<% #deals.each_with_index do |deal, i| %>
<% binding.pry %>
<%= "#{deal.title} - #{deal.price} - Rating: #{deal.deal_rating}" %>
<% end %>
This way inspecting with pry you take the first element from #deals:
[1] pry(#<#<Class:0x007fe0cd161ee8>>)> #deals.first
=> #<Deal:0x007fe0cb2751d8
id: 1,
title: "Deal-0",
price: 764,
deal_rating: 93,
created_at: Sat, 01 Apr 2017 15:00:29 UTC +00:00,
updated_at: Sat, 01 Apr 2017 15:00:29 UTC +00:00>
If you want to do it in your views then use unless to check for the first element using the index:
<% #deals.each_with_index do |deal, i| %>
<% unless !i.zero? %>
<%= "#{deal.title} - #{deal.price} - Rating: #{deal.deal_rating}" %>
<% end %>
<% end %>
The difference is that with with_index you can use an optional parameter to offset the starting index, so you're specifying the index from where to start with with_index(1) not trying to get the first element, see this:
<% #deals.each.with_index(2) do |deal, index| %>
<%= "#{index}: #{deal}" %><br>
<% end %>
2: #<Deal:0x007fe0cb55ca90>
3: #<Deal:0x007fe0cb55c950>
4: #<Deal:0x007fe0cb55c810>
...
This starts from the index 2, and the other one from 0.
<% #deals.each_with_index do |deal, index| %>
<%= "#{index}: #{deal}" %><br>
<% end %>
0: #<Deal:0x007fe0cb55ca90>
1: #<Deal:0x007fe0cb55c950>
2: #<Deal:0x007fe0cb55c810>
3: #<Deal:0x007fe0cb55c6d0>
4: #<Deal:0x007fe0cb55c590>
