Prime Number - Data while loading
- by Emroot
Hi,
I was trying in Ruby on Rails how to find a prime number. Here is my code :
helper : app/helpers/test_helper.rb
module TestHelper
def prime_number? number
index = 2
tmp = 0
while index <= number
if tmp < 1
if (number % index) == 0
tmp += 1
end
else
return false
end
index += 1
end
return true
end
end
and my view : app/views/test/index.html.erb
<% (2..100).each do |i| -%>
<% if prime_number? i %>
<%= i %>
<% end -%>
<% end -%>
So my question is : How can you load data while it's calculating ? I mean if I replace 100 by 100000 in my view, how can I see data on my view while my helper method is calculating ?
Do I need to use ajax or rails provide a tool for that ?
Thank you.
