Ruby on Rails ActiveAdmin step by step setup and configuration

Integrating ActiveAdmin into a Ruby on Rails project is a straightforward process that involves a few simple steps. First, you need to add the ActiveAdmin gem to your Gemfile and run the bundle install command to install it. Here's an example of how to add the gem to your Gemfile:

gem 'activeadmin'

Next, you need to run the ActiveAdmin generator to create the necessary files and directories. You can do this by running the following command:

rails generate active_admin:install

This will create several files and directories, including an initializer file, a stylesheet, and a JavaScript file. It will also create an admin directory where you can define your ActiveAdmin resources.

# app/admin/products.rb

ActiveAdmin.register Product do
  permit_params :name, :description, :price
end

This will create a basic administration interface for your Product model, allowing you to manage its attributes and view its data. You can customize this interface by adding filters, custom actions, and other features as needed.
