activeadmin-settings

IN DEVELOPMENT

TODO: use yaml file only for settings synchronisation, all settings should be stored in db with all those default values and other meta.

Easy to use general purpose settings backend for activeadmin.

Installation

Add to Gemfile:

gem "activeadmin-settings"

Run installer:

$ rails g activeadmin_settings:install

Add i18n configuration to config/application.rb file:

config.i18n.default_locale = :en
config.i18n.available_locales = [:en, :ru]

ActiveRecord

gem "aws-s3"
gem "fog"
gem "mini_magick"
gem "carrierwave"

gem "bson_ext"
gem "devise"
gem "activeadmin-settings"

Run migrations:

$ rake activeadmin_settings:install:migrations
$ rake db:migrate

Mongoid 2.x

If you're using mongoid 2.x the gem expects to see activeadmin-mongoid and carrierwave-mongoid (for image uploading feature) in Gemfile. Here is a working example:

gem "aws-s3"
gem "fog"
gem "mini_magick"
gem "carrierwave-mongoid"

gem "bson_ext"
gem "mongoid"
gem "mongoid-globalize"
gem "devise"
gem "activeadmin-mongoid"
gem "activeadmin-settings"

Mongoid 3.x

Here is an example of Gemfile with a support of 3.x version:

# Mongoid 3.x
gem 'moped',    git: 'git://github.com/mongoid/moped.git'
gem 'mongoid',  '~> 3.0.5'

# Assets
gem 'aws-s3'
gem 'fog'
gem 'mini_magick'
gem 'carrierwave-mongoid',  git:      'git://github.com/jnicklas/carrierwave-mongoid.git',
                            branch:   'mongoid-3.0',
                            require:  'carrierwave/mongoid'

# Activeadmin
gem 'devise',               '>= 2.1.2'
gem 'activeadmin-mongoid',  git: 'git://github.com/elia/activeadmin-mongoid.git'
gem "mongoid-globalize"
gem 'activeadmin-settings'

Configuration

After installation you should find a new Settings menu in the admin. If no configuration found in config/activeadmin_settings.yml only Admins tab is shown. Admin tab implements basic functionality of editing User objects.

To add some settings go to config/activeadmin_settings.yml. Settings are splitted into groups, each setting name concidered to be uniq, e.g.:

SEO:
  Website Keywords:
    description:    These keywords are included in homepage header meta tag
    default_value:  lorem ipsum simply dummy text printing

  Website Description:
    type:           text
    description:    Website description is used as value for header meta tag on homepage
    default_value:  Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.

There are a few types of settings:

• string (default) - a regular text input
• link - text input with a format: (TITLE) URL
• text - textarea input
• html - textarea with redactor.js
• file - input for file upload

Some examples:

Types Examples:
  Logo Image:
    type:           file
    description:    Please make sure logo image size is 287x140 pixels
    default_value:  home/home-logo.jpg

  CEO Message:
    type:           html
    description:    This text is used for the "CEO Message" page
    default_value:  >
                      <p><strong>Lorem Ipsum</strong> is simply dummy text of the printing and typesetting industry.</p>
                      <p>Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.</p>

  Facebook Link:
    type:           link
    description:    Company facebook page link
    default_value:  (Facebook) https://www.facebook.com/

Localization Example:
  Welcome title:
    type:           string
    description:    Localized welcome title
    default_value: 
      en: English default title
      ru: Russian default title
      de: German default title

Settings could be integrated into templates as well as models or controllers code using settings_value helper. For example:

• <%= settings_value("CEO Message") %> - provides html
• <%= settings_value("CEO Message", :de) %> - provides localized html for German language
• <%= image_tag setting_value("Logo Image") %> - provides an image url: <img src="/production-assets-path/home/home-logo.jpg" />
• <%= settings_value("Facebook Link") %> - provides link: <a href="https://www.facebook.com/" title="Facebook">Facebook</a>

If setting value is null or an empty string default setting value is used which is defined in config/activeadmin_settings.yml. If locale is not specified, default is used.

FUTURE FEATURES

I'm going to add types:

• Boolean - checkbox or dropdown with two values
• Dropdown - dropdown with options
• List - list bases selection
