# Use Avo in an api_only Rails app

You might have an api-only Rails app where you'd like to use Avo. In my early explorations I found that it needs the ::ActionDispatch::Flash middleware for it to properly work.

So, add it in your application.rb file.


















 



require_relative "boot"

require "rails/all"

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

module RailApi
  class Application < Rails::Application
    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 7.0

    # 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.middleware.use ::ActionDispatch::Flash
  end
end
