My project uses Rails 5.2, Ruby 2.4.1p111.
Rails 5.2 comes with active_record "pre-installed", rails active_storage:install that generated the Migrations, then rails db:migrate All right, in the model Category.Rb I put has_one_attached :image.
However has_one_attached is not recognized.
In my config/application.Rb I have require 'rails/all' which imports the active_record together.
config/Storage.yml looks like this
test:
service: Disk
root: <%= Rails.root.join("tmp/storage") %>
local:
service: Disk
root: <%= Rails.root.join("storage") %>
Does anyone have any idea what it might be?
That’s the mistake that returns to me:

I have the same problem: Active Storage + rails_admin. After much research and little success, I decided to create a defect in Github: https://github.com/sferik/rails_admin/issues/3025 Still no answer, we will follow.
