This plugin is no longer supported.

Greate rails_admin gem does not work with another great gem - acts_as_taggable_on, because rails_admin knows nothing about the virtual attributes *_list (tag_list, skill_list etc.), which created by acts_as_taggable_on for display and edit tags.

This problem is solved with rails_admin_tag_list gem.

In your Gemfile:

gem 'rails_admin'
gem 'rails_admin_tag_list'

and run:

$ bundle install

Check acts_as_taggable_on docs in order to install it properly.

rails_admin_tag_list by default does the following:

1. Register new field type TagList for rails_admin
2. Finds acts_as_taggable_on virtual attributes (*_list - tag_list, skill_list etc.) and adds them to RailsAdmin.config

There is your model:

class Player < ActiveRecord::Base
  acts_as_taggable
  acts_as_taggable_on :skills
end

Note that tag_list (skill_list, etc.) attribute should be available for mass-assignment by rails_admin users.

Since Rails 3.2.3 config.active_record.whitelist_attributes option is true by default; this means that you should put tag_list (skill_list, etc.) attribute in the white list, like in example above:

attr_accessible :tag_list, :skill_list

edit field view

In addition to default field view (named form_tag_list) this gem provides two custom views tag_list_with_suggestions and tag_list_with_autocomplete. To enable any of them specify partial name:

RailsAdmin.config do |config|
  config.model Player do
    edit do
      fields_of_type :tag_list do
        partial 'tag_list_with_suggestions'

        # the option sets max count of suggestions (default is 100); set -1 to abolish the limit
        ratl_max_suggestions -1
      end
    end
  end
end

You can do with tag_list fields whatever what allows to do rails_admin:

rename label

RailsAdmin.config do |config|
  config.model Player do
    edit do
      field :tag_list do
        label "Tags"
      end
      field :skill_list
    end
  end
end

hide all tag_list fields

RailsAdmin.config do |config|
  config.model Player do
    edit do
      fields_of_type :tag_list do
        hide
      end
    end
  end
end

reassing partial

RailsAdmin.config do |config|
  config.model Player do
    edit do
      fields_of_type :tag_list do
        partial 'awesome_tag_list'
      end
    end
  end
end

Create you custom partial and put it to app/views/rails_admin/main/ in your own project folder. Check an example
