Create action balance on dashboard

[Maria Serrano Cáceres]

I don't understand very good yet how it works rails_admin gem for create a new action.

I want create a action "balance" in root.

I have created a file with name "rails_admin_balance.rb" lib folder like:

    require 'rails_admin/config/actions'

    require 'rails_admin/config/actions/base'

    module RailsAdminBalance

    end

    module RailsAdmin

      module Config

        module Actions

          class Balance < RailsAdmin::Config::Actions::Base

           RailsAdmin::Config::Actions.register(self)

            register_instance_option :object_level do

              true

            end

            register_instance_option :link_icon do

             'icon-eye-open'

            end

            register_instance_option :root? do

              true

            end

          end

        end

      end

    end

I have created a new file on /views/rails_admin/main/balance.html.erb

inside my rails_admin.rb file I have

config.actions do

    dashboard                     # mandatory

    # collection actions 

    index                         # mandatory

    new

    export

    history_index

    bulk_delete

    # member actions

    show

    edit

    delete

    history_show

    show_in_app

    balance 

  end

When I try run rails server I get this error:

Exiting

/home/ubuntu/Desktop/myapp/config/initializers/rails_admin.rb:33:in `block (2 levels) in <top (required)>': undefined method `balance' for RailsAdmin::Config::Actions:Module (NoMethodError)....

Where have I the error?

What am I doing bad?

Thank you very much!

I was trying to do the same and i cant, what i did was create a new custom action like a plugin:
