rails active_storage:install IS NOT WORKING

Question

I have updated my rails api application from 5.1 to 5.2. I am using rails api only. I am trying to use the active storage. I think the problem is due to the line config.api_only = true in config/application.rb.

I did lot of google but did not find any thing how to use active storage in rails api.

Here is my Gemfile:

source 'https://rubygems.org'

ruby '2.5.1'

git_source(:github) do |repo_name|
  repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
  "https://github.com/#{repo_name}.git"
end

gem 'rails', '~> 5.2.0'
gem 'pg', '>= 0.18', '< 2.0'
gem 'puma', '~> 3.7'
gem 'rack-cors'

# Auth
gem 'bcrypt'
gem 'jwt'

#Media file upload
gem 'activestorage'

# gem 'devise', '4.4.3'
# gem 'devise-jwt', '~> 0.5.6'
gem 'active_model_serializers', '~> 0.10.0', require: true

# backgroud jobs
gem 'sidekiq'

# fast boot
gem 'bootsnap', require: false

group :development, :test do
  gem 'rspec-rails', '~> 3.7'
  gem 'brakeman'
  gem 'rubocop'
  gem 'byebug', platforms: [:mri, :mingw, :x64_mingw]
end

group :development do
  gem 'foreman'
  gem 'listen', '>= 3.0.5', '< 3.2'
  gem 'spring'
  gem 'pry'
  gem 'spring-watcher-listen', '~> 2.0.0'
  gem 'annotate'
end

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

Here is my config/application.rb

require_relative 'boot'

require "rails"
# Pick the frameworks you want:
require "active_model/railtie"
require "active_job/railtie"
require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "action_view/railtie"
require "action_cable/engine"
require "active_storage"
# require "sprockets/railtie"
require "rails/test_unit/railtie"

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module CelebrationBackend
  class Application < Rails::Application
    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 5.1

    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration should go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded.

    # Only loads a smaller set of middleware suitable for API only apps.
    # Middleware like session, flash, cookies can be added back manually.
    # Skip views, helpers and assets when generating a new resource.
    config.api_only = true

    config.active_job.queue_adapter = :sidekiq
    config.autoload_paths << Rails.root.join('lib')
  end
end

While running the rails activestorage:install in to console. I am getting the following error:

I am not getting the exact thing what I am doing wrong.

Answer 1

The current rails official documents talks about the new application. But if you're upgrading a pre 5.2 app, you have to add or uncomment the field in application.rb

require "active_storage/engine"

For the new application, this will be already added.

Answer 2

Your problem is here:

require "active_storage"

You need to require the engine:

require "active_storage/engine"

Answer 3

Try running command in the project root

bin/rails activestorage:install

or

rake active_storage:install
