Process in background not working

[JamesAndresCM]

Hi i'm trying to upload images in rails api, but this doesn't work

Uploader :

class ImgUploader < CarrierWave::Uploader::Base
  include ::CarrierWave::Backgrounder::Delay
  ...

Model :

class Character < ApplicationRecord
  mount_base64_uploader :img, ImgUploader
  process_in_background :img
  store_in_background :img
 ...

Response:

 Character Create (1.1ms)  INSERT INTO "characters" ("name", "bio", "img", "release", "created_at", "updated_at", "category_id", "img_processing", "img_tmp") VALUES ($1, $2, $3, $4, $5, $6, $7, $8, $9) RETURNING "id"  [["name", "Ioioioioijejid"], ["bio", "Iojdeidjeiod"], ["img", nil], ["release", "2019-01-31"], ["created_at", "2019-01-30 18:25:17.863165"], ["updated_at", "2019-01-30 18:25:17.863165"], ["category_id", 2], ["img_processing", true], ["img_tmp", "1548872717-95937-0001-2213/file.png"]]

Img not update from img_tmp

You should only be using either #process_in_background or #store_in_background. I would only recommend #store_in_background in the case where you have a shared tmp directory across your workers and web servers. I am actually going to remove it because it is confusing and not very useful.
