Ruby on Rails, Zendesk API integration not loading the client

Question

I am trying to set up the Zendesk API in my app, I have decided to go with the API that was built by Zendesk

I have set up the initializer object to load the client.

config/initializers/zendesk.rb

require 'zendesk_api'

client = ZendeskAPI::Client.new do |config|
  # Mandatory:
  config.url = Rails.application.secrets[:zendesk][:url]

  # Basic / Token Authentication
  config.username = Rails.application.secrets[:zendesk][:username]
  config.token = Rails.application.secrets[:zendesk][:token]

  # Optional:

  # Retry uses middleware to notify the user
  # when hitting the rate limit, sleep automatically,
  # then retry the request.
  config.retry = true

  # Logger prints to STDERR by default, to e.g. print to stdout:
  require 'logger'
  config.logger = Logger.new(STDOUT)

  # Changes Faraday adapter
  # config.adapter = :patron

  # Merged with the default client options hash
  # config.client_options = { :ssl => false }

  # When getting the error 'hostname does not match the server certificate'
  # use the API at https://yoursubdomain.zendesk.com/api/v2
end

This is pretty much copy paste from the site, but I have decided on using the token + username combination.

I then created a service object that I pass a JSON object and have it construct tickets. This service object is called from a controller.

app/services/zendesk_notifier.rb

class ZendeskNotifier
  attr_reader :data

  def initialize(data)
    @data = data
  end

  def create_ticket
    options = {:comment => { :value => data[:reasons] }, :priority => "urgent" }
    if for_operations?
      options[:subject] = "Ops to get additional info for CC"
      options[:requester] = { :email => '[email protected]' }
    elsif school_in_usa_or_canada?
      options[:subject] = "SRM to communicate with student"
      options[:requester] = { :email => '[email protected]' }
    else
      options[:subject] = "SRM to communicate with student"
      options[:requester] = { :email => '[email protected]' }
    end
    ZendeskAPI::Ticket.create!(client, options)
  end

  private
  def for_operations?
    data[:delegate] == 1
  end

  def school_in_usa_or_canada?
    data[:campus_country] == "US" || "CA"
  end
end

But now I am getting

NameError - undefined local variable or method `client' for #<ZendeskNotifier:0x007fdc7e5882b8>:
  app/services/zendesk_notifier.rb:20:in `create_ticket'
  app/controllers/review_queue_applications_controller.rb:46:in `post_review'

I thought that the client was the same one defined in my config initializer. Somehow I think this is a different object now. I have tried looking at their documentation for more information but I am lost as to what this is?

Answer 1

If you want to use the client that is defined in the initializer you would need to make it global by changing it to $client. Currently you have it setup as a local variable.
