V3.0.0.alpha : running in production is breaking

[RocKhalil]

For some reason, customizing actions ( or even including them ) in initializers/rails_admin.rb is breaking;

def add_action_custom_key(action, &block)
  action.instance_eval(&block) if block
  @@actions ||= []
  if action.custom_key.in?(@@actions.collect(&:custom_key))
    raise "Action #{action.custom_key} already exists. Please change its custom key."
  else
    @@actions << action
  end
end

Thrown error:

add_action_custom_key: Action dashboard already exists. Please change its custom key. (RuntimeError)

How does you config/initializers/rails_admin.rb look like?

RailsAdmin.config do |config|
  ### Popular gems integration

  ## == Devise ==
  config.authenticate_with do
    warden.authenticate! scope: :user
  end
  config.current_user_method(&:current_user)

  ## == Cancan ==
  # config.authorize_with :cancan

  config.parent_controller = '::ApplicationController'

  ## == Pundit ==
  # config.authorize_with :pundit

  ## == PaperTrail ==
  # config.audit_with :paper_trail, 'User', 'PaperTrail::Version' # PaperTrail >= 3.0.0

  ### More at https://github.com/sferik/rails_admin/wiki/Base-configuration

  ## == Gravatar integration ==
  ## To disable Gravatar integration in Navigation Bar set to false
  # config.show_gravatar = true

  config.actions do
    dashboard do
      statistics false # to disable the models load
    end

    index # mandatory

    new do
      except [
        UserAction,
        SystemLog,
        Song, SongAction, SongStat, SongStatsExternal
      ]
    end

    export

    bulk_delete do
      except [
        User,
        UserAction,
        SystemLog,
        SongAction, SongStat, SongStatsExternal
      ]
    end

    show

    edit do
      except [
        UserAction,
        SystemLog,
        SongAction, SongStat, SongStatsExternal
      ]
    end

    delete do
      except [
        User,
        UserAction,
        SystemLog,
        SongAction, SongStat, SongStatsExternal
      ]
    end

    show_in_app
    ## With an audit adapter, you can add:
    # history_index
    # history_show

    I18n.load_path += Dir["#{Rails.root}/lib/rails_admin/locales/*.yml"]
    Dir["#{Rails.root}/lib/rails_admin/actions/*.rb"].map { |f| [f, require(f)] }
    Dir["#{Rails.root}/lib/rails_admin/configuration/*.rb"].map { |f| [f, require(f)] }

    %i[approved live expired not_a_fit].each do |status|
      eval(''"
        song_status_update_#{status} do
          only [Song]
        end
      "'')
    end

    %i[claimed released].each do |status|
      eval(''"
        song_match_status_update_#{status} do
          only [SongMatch]
        end
      "'')
    end
  end
end

This works fine with Version 2.X

Hmm I can't reproduce locally...
Could you provide the full stack trace of this error?

add_action_custom_key: Action dashboard already exists. Please change its custom key. (RuntimeError)

[RocKhalil]

Did you try to run it with RAILS_ENV=production ? it's working on dev environment but not on production

[RocKhalil]

Basically, the add_action_custom_key error shows for dashboard, new, index etc... ( the main actions used by rails admin )

[mshibuya]

Thanks, I could reproduce. This issue should be related to this change, I'll investigate...

Pushed a fix in a branch, could you try it by putting

gem 'rails_admin', github: 'railsadminteam/rails_admin', branch: 'fix-initialization'

into your Gemfile?

[RocKhalil]

Works perfectly !
Thanks for the quick fix
