Rails views output is different than Puma web server logs - ruby-on-rails

Question

I have a ruby script called abc.rb in rails config/initializers
require 'http'
class Abc
def initialize(url)
#url = url
#doc = web_lookup(#url)
end
def web_lookup(url_to_open)
begin
return Nokogiri::HTML(HTTP.get(url_to_open).to_s)
rescue
"Please check your URL!"
end
end
def frequency_count
#word_array = #doc.css("p").text.split(" ")
#occurance = Hash.new(0)
#word_array.each {|x| #occurance[x.downcase] += 1 }
#occurance.each {|x,y|
if y > 5
puts "#{x} : #{y} times"
end
}
end
end
And I'm trying to access that script's class in a rails controller.
class UrlsController < ApplicationController
def index
#url_to_check = Abc.new("http://ecodehut.com/linux")
end
end
Everything is fine so far but when I call this variable in index.html.erb <%= #url_to_check.frequency_count %> output is this:
{"it’s"=>1, "like"=>1, "asking"=>1, "“should"=>1, "i"=>5, "go"=>3, "to"=>14, "school?”"=>1, "and"=>8, "“would"=>1, "get"=>1, "a"=>3, "job"=>1, "if"=>2, "school?”.list"=>1, "of"=>1, "advantages"=>1, "is"=>5, "never"=>1, "ending"=>1, "elaborating"=>1, "each"=>1, "throw"=>1, "your"=>2, "mouse"=>1, "away"=>1, "this"=>3, "time."=>1, "keyboard"=>1, "all"=>1, "need"=>1, "mozart."=>1, "navigate..."=>1, "before"=>2, "we"=>1, "begin"=>1, "with"=>3, "configuration"=>1, "here"=>1, "download"=>1, "install"=>2, "system."=>1, "after"=>1, "come"=>1, "back"=>1, "continue."=>1}
But my expected output is this:
to : 14 times
and : 8 times
you : 9 times
the : 6 times
I'm not getting why rails printing everything inside the hash instead of the key values with values bigger than 5 like mentioned in the frequency_count method.
P.S: Abc.rb script results fine and dandy when ran in terminal using ruby Abc.rb

Answer 1

Plese change this and try again
def frequency_count
#word_array = #doc.css("p").text.split(" ")
#occurance = Hash.new(0)
#word_array.each {|x| #occurance[x.downcase] += 1 }
#occurance.select {|x, y| y> 5}
end
The reason is the last line of your method is
#occurance.each {|x,y|
if y > 5
puts "#{x} : #{y} times"
end
}
Just iterate all key and values inside #occurance variable but not sort based on the count. So you are getting all key values in the views instead which has count more than 5.
When you do #occurance.select {|x, y| y> 5}, which filter your hash and gives you the desired values which count is more than 5. Now you can just loop it and print inside views.
Hope you understand.
Update
In your index.html.erb put this code, where you would like to print hash details
<% #occurance.each do |key, value| %>
<span><%= "#{key}: #{value}" %></span><br />
<% end %>
