Adding ActiveAdmin to a Rails 7 Application.

To add the ActiveAdmin gem to a Rails 7 application, follow these steps:

Add the ActiveAdmin gem to your Gemfile and run bundle install to install it.

gem 'activeadmin', github: 'activeadmin'

Run the ActiveAdmin installer to create the necessary configuration files and directories.

rails generate active_admin:install

Run the migrations to create the ActiveAdmin database tables.

rails db:migrate

Restart your Rails server to pick up the changes.

Now that ActiveAdmin is installed, you can create resources to manage your data. To do this, run the following command, replacing Product with the name of your model:

rails generate active_admin:resource Product

This will create a new file at app/admin/product.rb, which defines the ActiveAdmin resource for the Product model. You can edit this file to customize the way the resource is displayed and managed in the ActiveAdmin dashboard.

To access the ActiveAdmin dashboard, navigate to http://localhost:3000/admin in your web browser. You should see the login page, where you can enter the default username ([email protected]) and password (password) to log in.

Once you're logged in, you can click on the Products link in the menu to view and manage the Product resource. You can use the various controls on the page to create, edit, and delete records, as well as search and filter the data.

That's it! You should now have a working ActiveAdmin installation for your Rails 7 application. You can continue to customize the configuration and add more resources as needed to manage your data.
