rails active admin setup

 

What is the active admin ?

   Active Admin is a framework for creating administration style interfaces. It     abstracts common business application patterns to make it simple for developers to  implement beautiful and elegant interfaces with very little effort.


For this tutorial, I set up Two models.


rails generate scaffold Post title:string description:string 
 rails generate scaffold Comment content:text post:references
Migrate the database:

 $ rails db:migrate

The models have the following associations.

app/models/post.rb

class Post < ActiveRecord::Base
  has_many :comments
end

app/models/comment.rb

class Comment < ActiveRecord::Base
  belongs_to :post
end

Active Admin is a Ruby on Rails plugin for generating administration style interfaces. To set it up in your Rails project, you'll need to follow these steps:


Add the Devise gem to your Gem file:


 gem 'devise','~>4.8', '=> 4.8.1'

Add the Active Admin gem to your Gem file:



 gem 'activeadmin'


Run this commend to install the gem.

$ bundle install


Run the generator to create the required files:



 $ rails generate active_admin:install

Migrate the database:


 $ rails db:migrate

Visit  http://localhost:3000/admin and log in using:


  • User: admin@example.com
  • Password: password


    •    You`re on your brand new Active Admin dashboard


      To register your first model , and this comment in the terminal. 

       
     $ rails generate active_admin:resource [Post]
    rails generate active_admin:resource [Comment]
     
    This creates a file at app/admin/post.rb and app/admin/comment.rb for configuring the resource. Refresh your web
    browser to see the interface.
