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 AdminUser 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.

All of the settings may be cplitted to groupes by adding optional param group, e.g.:

Site Wide:
  Title:
    type:           text
    description:    Website Title
    group:          Slider
  Image1:
    type:           file
    group:          Slider
  Copyright:
    type:           text
    description:    eg. (c) 2015
    group:          Footer
  FooterLogo:
    type:           file
    group:          Footer

As result we'll see:

ActiveadminSettings Group Example

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
