  ## == Devise ==
  config.authenticate_with do
    default_locale =  :np

    # Set locale per request
    I18n.locale = params[:locale] || default_locale

    if current_user.blank? || (current_user.has_role?('super_admin') == false)
        flash[:error] = 'You are not authorized to access this resource.'
      redirect_to '/'
    end
  end

  config.current_user_method(&:current_user)

Copy yml file to your project

copy .rvm/gems/ruby-2.6.3/gems/rails_admin-1.4.2/config/locales/rails_admin.en.yml or https://raw.githubusercontent.com/sferik/railsadmin/master/config/locales/railsadmin.en.yml

to /config/locale/rails_admin.np.yml or rails_admin.[:locale].yml

Convert the file to your locale.

You might encounter a msg in view translation missing for np.datetime.distance_in_words.x_days
