Whois gem not working in rails

Question

class DomaincheckerController < ApplicationController
  def index
  end
  def store
    r =Whois.whois(secure_params['domain'])
    render :text => "#{r}"
  end

  private
  def secure_params
    params.require(:whois).permit(:domain)
  end


end

This is my domainchecker controller. The index method renders a form. After submitting the form it goes to store method. Here I am trying to use the whois gem. I have installed whois gem by running gem install whois. But I am getting this error.

uninitialized constant DomaincheckerController::Whois

Standard question in those cases: have you restarted the server after installing a gem? — BroiSatse, Oct 15 '15 at 16:05
@BroiSatse yes, I have restarted niginx as well as unicorn too — Raaz, Oct 15 '15 at 16:06
How did you restarted unicorn? USR2? You need to do hard restart. No need to reboot nginx. — BroiSatse, Oct 15 '15 at 16:07
@BroiSatse, I thought I restarted unicorn. I did `service unicorn_fuitter stop` and then ran `service unicorn_fuitter start` . But even when I did `service unicorn_fuitter stop` my app was still running. — Raaz, Oct 15 '15 at 16:13
Your etc script might be incorrect. Try restarting it manually using `kill --QUIT` — BroiSatse, Oct 15 '15 at 16:26
@BroiSatse kill --QUIT, gave me an error `-bash: kill: -QUIT: invalid signal specification` — Raaz, Oct 15 '15 at 16:28
@RajShakya - Have you give it a pid of your unicorn service? — BroiSatse, Oct 15 '15 at 16:35
ok, i have done hard restart and still it is showing me the `uninitialized constant DomaincheckerController::Whois ` err — Raaz, Oct 15 '15 at 16:40

The problem is that you installed the gem directly and not using bundler, therefore the Rails app can't find the dependency.

In order to install a gem in a Rails project you need to edit the Gemfile file and add the gem there. Once added, run

$ bundle

in order to install the dependency. Check the documentation about the Gemfile.
