Undefined local variable or method `searchkick'

Question

I'm trying to add Searchkick to my Rails application. I'm following the exact instructions on the Get started page but I keep getting the following error:

Started GET "/airports" for 10.0.2.2 at 2014-05-26 10:20:33 +0000
Processing by AirportsController#index as HTML
Completed 500 Internal Server Error in 26ms

NameError (undefined local variable or method `searchkick' for #<Class:0xb48f3ba8>):
  app/models/airport.rb:2:in `<class:Airport>'
  app/models/airport.rb:1:in `<top (required)>'
  app/controllers/airports_controller.rb:3:in `index'

  Rendered /home/vagrant/.rvm/gems/ruby-2.1.1@global/gems/actionpack-4.1.1/lib/action_dispatch/middleware/templates/rescues/diagnostics.erb within rescues/layout (19.8ms)

Here's what the Airport model looks like:

# ./app/models/airport.rb
class Airport < ActiveRecord::Base
    searchkick
end

And this is what the Airport controller looks like:

# ./app/controllers/airports_controller/rb
class AirportsController < ApplicationController
  def index
    @airports = Airport.all
  end
end

What's causing this?

Answer 1

Restart the server. The server has to be restarted after a change is made to the Gemfile.

Other things you can try if that doesn't work:

• add gem 'searchkick' to the Gemfile
• bundle install
