= AdMob Ruby on Rails integration code (for Rails 3 & Ruby 1.9)

* http://www.admob.com

== DESCRIPTION:

Enables easy integration of AdMob services (ads and/or analytics) into a RoR mobile site.

== SYNOPSIS:

=== Setting up

* Get a publisher_id and/or analytics_id from http://www.admob.com and/or http://analytics.admob.com
* Add <tt>require "admob"</tt> to app/controllers/application.rb, or to any specific controller as needed.
* Provide some or all default settings in your environment.rb . e.g. :
    require 'admob'
    AdMob::config do |c|
      c.publisher_id = 'YOUR_PUBLISHER_ID'
      c.analytics_id = 'YOUR_ANALYTICS_ID'
      c.timeout = 1
      c.encoding = 'UTF-8'
      c.raise_exceptions = false
      c.cookie_domain = 'example.com' # you can override this setting in AdMob::set_cookie()
      c.cookie_path = '/' # you can override this setting in AdMob::set_cookie()
    end
* In a view, where you want an ad, place an ad request.
* Note: You must provide your publisher_id and/or analytics_id in the default setting, or when you make the ad request (see below).

=== Using Cookies

* AdMob now uses cookies to enhance ad targeting and analytics data.
* The easiest way to enable AdMob cookies on your website is to add the following code snippet to your ActionController::Base class (usually in app/controllers/application.rb)
* This will cause AdMob::set_cookie() to be executed on every request (the function will return immediately if a cookie does not need to be set)

    require 'admob'
    class ApplicationController < ActionController::Base
    
      ## begin AdMob cookie snippet ##
      before_filter :admob_set_cookie
      
      def admob_set_cookie
        AdMob::set_cookie(request, cookies)
      end
      ## end AdMob cookie snippet ##
      
    end
  
=== Configuring Cookies (IMPORTANT if your site uses multiple subdomains)

* By default, the domain of the cookie is for the host that set it. This means that cookies set from a.example.com are not visible from b.example.com
* To allow AdMob cookies to be visible everywhere on your site, you need to set a default cookie domain in environment.rb
* The default cookie domain should be the root domain of your mobile site (e.g. "example.com", "example.co.uk") 

    require 'admob'
    AdMob::config do |c|
      c.cookie_domain = 'example.com' # if your main domain is www.example.com
      c.cookie_domain = 'example.co.uk' # if your main domain is www.example.co.uk
    end

=== Sample requests

==== If you've configured a default publisher and/or analytics id

 <%= AdMob::request(request, session[:session_id]) %>

==== If you didn't configure a default publisher_id or want to override the configured default publisher_id

 <%= AdMob::request(request, session[:session_id], :publisher_id => "YOUR_PUBLISHER_ID") %>

==== Request a test ad (happens by default when in test or development mode)

 <%= AdMob::request(request, session[:session_id], :test => true) %>

==== Request an ad, providing demographic info and keywords

 <%= AdMob::request(request, session[:session_id], :publisher_id => "YOUR_PUBLISHER_ID", :dob => "19800229", :gender => "male", :postal_code => "90210", :keywords => 'ruby gem admob') %>

==== Make an analytics request only

 <%= AdMob::request(request, session[:session_id], :ad_request => false) %>

See the documentation for #AdMob::request for a list of all params that can be set for a request.
