I used the rails admin gem to add admin to my website. It was easy! I added gem 'rails_admin', '~> 2.0' to my Gemfile and ran bundle install in my terminal. Then, I updated my users table to have a boolean for admin, below is a sample users schema:
create_table "users", force: :cascade do |t|
t.string "username"
t.text "email"
t.datetime "created_at", precision: 6, null: false
t.datetime "updated_at", precision: 6, null: false
t.string "password_digest"
t.boolean "admin", default: false
t.string "encrypted_password", limit: 128
t.string "confirmation_token", limit: 128
t.string "remember_token", limit: 128
t.index ["email"], name: "index_users_on_email"
t.index ["remember_token"], name: "index_users_on_remember_token"
end
Then I ran rails g rails_admin:install and rails db:migrate.
I went over to http://localhost:3000/admin in my browser and I was able to see my admin dashboard.
One problem though, ANYONE WHO IS ANYONE COULD SEE MY ADMIN DASHBOARD.
So when I ran rails g rails_admin:install it gave me the rails admin file in config/initializers/rails_admin.rb
I wanted to only allow users that had admin privileges to be able to see the admin dashboard. I ran into a few issues while trying to add cancancan so I added it manually in the config/initializers/rails_admin.rb file:
RailsAdmin.config do |config|
### Popular gems integration
# config.authorize_with :cancancan
config.parent_controller = "::ApplicationController"
config.authorize_with do
if !current_user || !current_user.admin?
redirect_to(main_app.root_path, alert: "You are not permitted to view this page")
end
end
config.actions do
dashboard # mandatory
index # mandatory
new
export
bulk_delete
show
edit
delete
show_in_app
end
end
The above will redirect anyone back to the main root page, if they are not admin.
I plan to use cancancan in my next project with the devise gem but for now this simple fix worked well.
Thanks for reading!
Sincerely,
Brittany

Day 68! Impressive:) By the way, I am very curious as to how to create those DEV series liquid tag within the article like yours, what's the syntax that you use to include that?
Hi Liu! Thank you ☺️ I created a series within Dev.to. When you create a series it automatically makes the liquid tags. Check this article out and let me know if you need any help :)
