How create a new rails app with activeadmin v4

[inyerade]

Hi, I need some help to create a new app with activeadmin version 4. I do not know what step I miss.

INSTALLATION

1. create ralis app

    rails _7.1.3.2_ new aa_tailwind_rails --database=sqlite3 --css=tailwind --js=importmap

2. Add AA and devise in Gemfile

    ...
    gem "activeadmin", "4.0.0.beta7"
    gem "devise"
   ...

3. run command to install

    bundle install
    rails g active_admin:install User
    rails db:migrate
    rails db:seed

4. Create page outside activeadmin (/admin) to check tailwind works

In routes.rb add get "dashboard", to: "application#dashboard"

create file in app/views/shared/dashboard.html.erb with:

<h1 class="text-3xl font-bold underline">
    Hello world!
</h1>

Add dhasboard in application_controller.rb

class ApplicationController < ActionController::Base
    def dashboard
        render "shared/dashboard"
    end
end

5. Run server

rails server

RESULT

Outside activeadmin result (OK)

Activeadmin result (NOT OK)

Can anyone help?

@inyerade I believe the problem is the --css=tailwind flag which actually uses the tailwindcss-rails gem which we don't support currently. That may change in the future as authors of that gem are looking into engine support. In the UPGRADING guide it's mentioned that the expectation is to use cssbundling-rails instead. If you still prefer to use tailwindcss-rails, there is a helpful discussion on how to do that that you can try. Thank you.

thanks @javierjulio for the clarification. I read both link and I do not understand very well the processI think I will stay to version 3 for a while.
