Steps required to get FlexiAdmin working with a Rails app:

Gemfile

1. add gem 'flexi_admin', git: 'https://github.com/landovsky/flexi_admin.git', branch: 'main' to the Gemfile

Stylesheets

2. add @import "flexi_admin.scss"; to the app/assets/stylesheets/application.scss file

JavaScript

3. add import "flexi_admin"; to the app/javascript/application.js file

• can't get stylesheets to load from gem, so adding to host app:

// Production
// @import "flexi_admin.scss";
// Local dev
// @import "../../flexi_admin/app/assets/stylesheets/flexi_admin";

• add modals controller:

# frozen_string_literal: true

class ModalsController < AdminController
  include FlexiAdmin::Controllers::ModalsController
end

  resources :modals, only: [] do
    get :show, on: :collection
  end
