Ruby/Rails - Remove ActiveAdmin from my application

Question

I had a good time playing with Active Admin the administrative framework within my application. http://activeadmin.info/

When I installed it I ran

rails g active_admin:install
rake db:migrate
rails g active_admin:resource product

and it generated alot of migrations and code within my application.

My question if I would like to go back and have everything that active_admin put into my application taken out, how would i do so?

Is there one 'rails active_admin:uninstall' command to get rid of everything or do I have to manually create migrations to delete all the tables and search through my code to see what it added?

Do you use version control? – Andrew Grimm Jun 23 '17 at 04:19 — Andrew Grimm, Jun 23 '17 at 04:19

If you run the following code it should destroy active admin:

rails destroy active_admin:install
rails destroy active_admin:resource product

You don't even need the second line it seems. – David Tuite Dec 13 '11 at 07:22

Also, keep in mid that if you set up an `AdminUser` model when you added ActiveAdmin, this will destroy it, along with any methods you added to it. – David Tuite Dec 13 '11 at 07:35

Beware that some trash code will be left in 'routes.rb' and 'schema.rb'. Do a search for 'admin' and comment the unnecessary code, or it may cause errors later. – chech Jun 05 '13 at 15:28

do i need to rollback the migration – lngs Sep 30 '13 at 12:02
Also remove `gem 'activeadmin'` from your gem file or it will install again next time you bundle = ] – rii Aug 18 '15 at 04:08

Run this in terminal

rails destroy active_admin:install

Remove gem 'activeadmin' from your gemfile.

Delete the asset files from js and css folders if any remain

Delete any of these lines in Routes.rb

  devise_for :admin_users, ActiveAdmin::Devise.config
  ActiveAdmin.routes(self)
  ActiveAdmin.routes(self)

Then create a new migration with:

  drop_table :active_admin_comments

You may also need:

  drop_table :admin_notes

Or rollback the migrations by finding the relevant files MoveAdminNotesToComments and CreateAdminNotes in your db/migrate folder

rake db:migrate:down VERSION=the_version_number
rake db:migrate:down VERSION=the_version_number

The new drop migration is much cleaner than the rollback one, but thanks for making this good answer, everything is in here ;) – gfd Feb 06 '15 at 21:16

For everyone ease, I did : `rails generate migration drop_active_admin_comments` modified the migration like this: `` class DropActiveAdminComments < ActiveRecord::Migration def up drop_table :active_admin_comments end def down raise ActiveRecord::IrreversibleMigration end end `` `` bundle exec rake db:migrate `` the table and indexes are gone ;) – gfd Feb 06 '15 at 21:30
Ok, I just don't know how to format a comment with code in it... so I've finally been rejected the right to reedit my previous comment :/ – gfd Feb 06 '15 at 21:37

Oh and don't forget to remove the `gem 'active_admin' ` entry in your Gemfile once the `rails destroy active_admin:install` is done ;) – gfd Feb 06 '15 at 21:39
Yes. Thank you I have done this now. It works. Destroyed the active_admin and reinstalled the latest version. Rails and Windows 7 dont like eachother much :D – zer02 May 16 '15 at 17:46

You also need to delete all the active admin related js and css files in your assets folder after running rails destroy active_admin:install
