Rails duplicate loop - Hash and array loop - ruby-on-rails

Question

In my view I have:
<% #results.each_pair do |country_code, available| %>
<% #prices.each do |cc,domain| %>
<% klass = available.registered? ? "pinfo" : "info" %>
<span class="<%= klass %>"></span>
<%= #domain + country_code %> <%= domain.send(cc) %>$<br />
<% end %>
<% end %>
And the output is:
asdsaddk 8$
asdsaddk 1$
asdsadcom 8$
asdsadcom 1$
My controller:
def domain
country_codes = %w[ dk com ]
#domain = "asdsad"
#results = { }
#prices = { }
country_codes.each do |cc|
#results[cc] = Whois.whois("#{#domain}.#{cc}")
#prices[cc.to_sym] = Domain.order(cc).first
end
render :layout => false
end
How do I create a normal loop like where the output is not duplicate like:
asdsaddk 8$
asdsadcom 1$

Answer 1

Replace:
<% #results.each_pair do |country_code, available| %>
<% #prices.each do |cc,domain| %>
<%= #domain + country_code %> <%= domain.send(cc) %>$<br />
<% end %>
<% end %>
With:
<% #prices.each do |cc,domain| %>
<%= #domain + cc.to_s %> <%= domain.send(cc) %>$<br />
<% end %>
Indeed, you don't use the available variable from #results.
Sidenote: once again, you don't have any array here, only Hashes.
Reorganization needed:
def domain
country_codes = %w[ dk com ]
#domain = "asdsad"
#output = { }
country_codes.each do |cc|
#output[cc.to_sym] = { :whois => Whois.whois("#{#domain}.#{cc}"),
:domain => Domain.order(cc).first }
end
render :layout => false
end
In your view:
<% #output.each do |cc, hash| %>
<span class="<%= hash[:whois].registered? ? "pinfo" : "info" %>"></span>
<%= #domain + key.to_s %> <%= hash[:domain].send(cc) %>$<br />
<% end %>
