Sidekiq - Sinatra - Can't read from my ActiveRecord Objects - ruby

Question

For some reason, my sidekiq worker can't read from my ActiveRecord models. Here is my worker class. It fails on line where its trying to read from my User object: name = User.find_by(id: user_id).first_name.
require 'gcm'
module Socio
class RequestNotificationWorker
include Sidekiq::Worker
sidekiq_options retry: false
def perform(target_token, key)
begin
gcm = GCM.new(key)
registration_ids= [target_token]
options = {notification: {title: "Connection request!", body: "You have a new Socio request.",
sound: "default", badge: 1, type: "1"},
collapse_key: "New Connections", content_available: true, priority: "high"}
gcm.send(registration_ids, options)
{success: true}
rescue => e
{success: false, error: e.to_s}
end
end
end
class ConfirmNotificationWorker
include Sidekiq::Worker
sidekiq_options retry: false
def perform(target_token, key)
begin
gcm = GCM.new(key)
name = User.find_by(id: #user_id).first_name
registration_ids= [target_token]
options = {notification: {title: "Connection Confirmed!", body: "#{name} has accepted your Socio request.",
sound: "default", badge: 1, type: "2"},
collapse_key: "New Connections", content_available: true, priority: "high"}
gcm.send(registration_ids, options)
{success: true}.to_json
rescue => e
{success: false, error: e.to_s}
end
end
end
end
Also here is my procfile:
web: bundle exec thin start -p $PORT
worker: bundle exec sidekiq -c 5 -v -r ./app/sidekiq.rb
And here is the error message:
Failed uninitialized constant Socio::ConfirmNotificationWorker::User
I tried different require and include commands, but couldn't get it to work.

Answer 1

Somewhere inside app/sidekiq.rb you need to require activerecord and user.rb. If you show us your sidekiq.rb it will help.

Answer 2

This is because app/sidekiq is not initializing your application - you have probably all relevant require statements in the main application file (app.rb). Compare app/sidekiq.rb with app.rb file (and possible other files in the tree) and add relevant require instructions in the first one.
You can also start the console session (for example using Pry: pry -r ./app/sidekiq.rb or built-in irb: irb -r ./app/sidekiq.rb) with app/sidekiq and check if all needed classes are there or even better: write specs to check if it works fine.
