Rails + Sidekiq not recognizing class

Question

I have a CsvImport service object in my app/services and I'm trying to call one of the class methods from within a Worker.

class InventoryUploadWorker
  include Sidekiq::Worker

  def perform(file_path, company_id)
    CsvImport.csv_import(file_path, Company.find(company_id))
  end
end

But it seems that the worker doesn't know what the class is, I've attempted require 'csv_import' to no avail.

Heres where it breaks:

WARN: ArgumentError: undefined class/module CsvImport

The method being called in csv_import.rb

class CsvImport
require "benchmark"
require 'csv'


def self.csv_import(filename, company)
    time = Benchmark.measure do
        File.open(filename) do |file|
            headers = file.first
            file.lazy.each_slice(150) do |lines|
                Part.transaction do 
                    inventory = []
                    insert_to_parts_db = []
                    rows = CSV.parse(lines.join, write_headers: true, headers: headers)
                    rows.map do |row|
                        part_match = Part.find_by(part_num: row['part_num'])
                        new_part = build_new_part(row['part_num'], row['description']) unless part_match
                        quantity = row['quantity'].to_i
                        row.delete('quantity')
                        row["condition"] = match_condition(row)
                        quantity.times do 
                            part = InventoryPart.new(
                                part_num: row["part_num"], 
                                description: row["description"], 
                                condition: row["condition"],
                                serial_num: row["serial_num"],
                                company_id: company.id,
                                part_id: part_match ? part_match.id : new_part.id
                                )           
                            inventory << part                   
                        end
                    end
                    InventoryPart.import inventory
                end
            end
        end         
    end
    puts time
end

Answer 1

your requires are inside the class. Put them outside the class so they're required right away when the file is loaded, not when the class is loaded.

Instead of

class CsvImport
require "benchmark"
require 'csv'
...

Do this

require "benchmark"
require 'csv'
class CsvImport
  ...

Answer 2

Try to add to application.rb

config.autoload_paths += Dir["#{config.root}/app/services"]
