How can I don't keep changing Active Storage attachments URLs?

Question

Every time I retrieve an ActiveStorage attachment URL (using object.attachment.service_url), is a new one. Is there a way to use always the same one?

EDIT

storage.yml file

amazon:
  service: S3
  access_key_id: <%= ENV['AWS_KEY'] %>
  secret_access_key: <%= ENV['AWS_SECRET'] %>
  region: 'sa-east-1'
  bucket: 'production-bucket'

test:
  service: S3
  access_key_id: <%= ENV['AWS_KEY'] %>
  secret_access_key: <%= ENV['AWS_SECRET'] %>
  region: 'sa-east-1'
  bucket: 'staging-bucket'

local:
  service: Disk
  root: <%= Rails.root.join("storage") %>

Maybe this line can help you

Rails.application.routes.url_helpers.rails_blob_path(Object.attachement, only_path:true)

You can add this method to your model

def attachment_url
    if self.attachment.attached?
      Rails.application.routes.url_helpers.rails_blob_path(self.attachement, only_path:true)
    else
      nil
    end
  end

And call it from anywhere.

If your model has many attachments

def attachment_url(item_attached)
    if item_attached.attached?
      Rails.application.routes.url_helpers.rails_blob_path(item_attached, only_path:true)
    else
      nil
    end
  end

Object.attachement_url(Object.image)
